Servo Controller (1394) Product Selection Guide
Servo Controllers are an essential part of a servo system. The 1394 Servo controllers are not only modular but also multi-axis mobility controller drive technologies. Motors, a monitoring network, and a servo controller are the three major parts of a servo system. The 1394 Servo controller has an operational frequency of fifty (50) to sixty (60) hertz, as well as a rated AC input voltage range of 324 to 528 Volts AC. The 1394 Servo Controllers have a module-to-module connection system, IGBT power conversion, and 3-phase input power. An ambient temperature range of 0 to 65 degrees Celsius is recommended where the controllers are to be mounted. At 1000 meters above sea level, the controllers may be used without suffering any degradation. Corrosive elements should not be present in the installation environment.
Increased feedback controllers and absolute multi-turn encoders are both included in these Servo Controllers. 1394 Servo Controllers can synchronize complicated motion applications. The 1394 controllers also offer Remote I/O, enabling 1394 devices to talk to positional controllers, as well as various RIO devices that are compatible with Allen-Bradley products. The droop control function, a speed control mode utilized in an AC system, is a feature of the 1394 servo controllers. The 1394 controllers include LED signals that light up when a malfunction occurs. When errors happen, a restore button is provided to restart the controllers. On the outside of 1394 controllers, there is one LED for the system module and one LED for each axis module.
Advantages of the 1394 Servo Controller That Make it Stand Out
Affordability of the Controller
The Allen-Bradley 1394 servo controller’s distinctive integral design provides the best multi-axis motion alternative: a much more affordable solution that is simple to deploy, connect, and use.
Simple Networking and Connections
These servo controllers often use the SERCOS fiber-optic network to communicate, and it is incorporated into the ControlLogix systems. There is a 1394 configuration to suit various requirements, whether the application needs the connection with Logix that a SERCOS interface mobility module offers, the simple networking that connects PLC and SLC systems to the 1394 action monitor, or a standalone 1394 servo drive.
Compact Design
Also included in the design of 1394 products is a slide-and-lock attachment that gets rid of as many as 100 separate wire endpoints amongst modules. An application-specific fit is made possible by the autonomous choice of the network power source plus axis drive energy rating. The system power generator's improved structure offers greater reliability with fewer components. Furthermore, flexible module arrangement is also available.
Major Features of the 1394 Servo Controller
With a regular selection of hardware, the 1394 Servo Controller accommodates Standard GMC, Turbo GMC, and Analog Servo arrangements. Various system inertias are supported by a digitally controlled velocity and current loop adjustment. It contains two programmable analog test outputs (GMC and Analog Servo system modules) that may be connected to important system variables for troubleshooting. Diagnostic tools, such as a current analyzer, overheat monitoring, and a response signal check, are provided by all systems. For encoder emulation, there is an encoder signal output (A QUAD B). It has processing capability with DSP assistance. On many of the system modules as well as axis modules, there are improved grounding terminations.
IGBT technology is available for effective, silent operation. It has ground fault protection, phase loss, and transient (MOV) voltage. There is a 200W shunt resistor built into it. A 1400W external shunt kit is readily accessible. A continuous torque range of 0.7 to 53.0 N-m is produced at 7.5, 4.5, and 3.0 amperes of continuous current at 50°C. Furthermore, this device has a 35-ampere and 23.3-ampere continuous current rating at 40°C. For most applications, direct line operation without an isolation transformer or inductors is sufficient. Advanced safety measures include soft current limiting that allows for safe operation.
For easy removal, as well as simple swapping during troubleshooting and diagnosis, there are system and axis modules. Axis modules come in standard widths of 50 mm and 75 mm. For simple installation and maintenance, contact-type terminal blocks and mass termination plugs are employed.
Bus bars and wire harnesses are not necessary since it connects modules using a slide-and-lock mechanism. The 1394 controller's advanced communications and I/O capabilities aid in integrating it with common plant floor networks.
System Overview of the 1394 Servo Controller

CNC System 9/440
This small 1394 system module's design allows the 9/440 to provide the usability and technical skills of a 9/Series CNC. Encoder feedback, resolver, E-STOP text and status, spindle outputs, and resolver termination points are all provided by the 9/440 CNC System Module.
Components of the 1394 System
One (1) system module, two (2) to four (4) axis modules, one (1) to four (4) servo motors, and one (1) to four (4) power and feedback connections make up the 1394 system. Along with the equipment listed above, there are two types of three-phase input devices: contactors and fuses with a 24-volt logic power, and a system module.
For 5 and 10-kilowatt systems with regenerative loads greater than 200 watts, an interior shunt resistor and an exterior shunt resistor kit are offered. The majority of 5 and 10-kilowatt systems won't need shunt resistor kits. An extra shunt module is required for all 22 kW 1394-based devices. Both 1394 and 8520-series products are included in this.
System Module
The system module holds the system management PCB and converts 360 to 480 VAC. Moreover, this is to convert 50 or 60-hertz inputs to a voltage range of 530 to 680 VAC. They are available with ratings of 5, 10, and 22 kilowatts at 460 volts. An exterior shunt module is required for the 22-kilowatt system module. The AC-related current inputs of the 1394x-SJT05, 1394x-SJT10, and 1394x-SJT22 are 6.5 amperes, 13.0 amperes, and 28.6 amperes, respectively. The efficiency of the 1394x-SJT22 is around 98 percent while the 1394x-SJT05 and 1394x-SJT10 have an efficiency of 99 percent. The line loss for all three of the modules is 20 milliseconds. The inductance rating of the 1394x-SJT05 is 1000 µH, the 1394x-SJT10 is 750 µH, and the 1394x-SJT22 is 500 µH. The peak power output of the 1394x-SJT05 is 28 kW, the 1394x-SJT10 is 28 kW, and the 1394x-SJT22 is 136 kW. The Electronic Cam Profile Points of all three is 13000 Master/slave. These modules transform the DC power provided into a variable AC voltage with steady output currents (RMS) of 35.0 amperes, 23.3 amperes, 7.5 amperes, 4.5 amperes, and 3.0 amperes. Depending on the servo motor's present needs, the user must choose an appropriate axis module.
External Shunt Module
With the smart power 22-kilowatt system module, there are shunt modules with a continuous power output of 3600 watts, 1800 watts, 900 watts, and 300 watts. There are also modules of 160,000-watt peak output. The Bulletin 1394 system's extra regenerative power is dissipated via the shunt module. Every 22-kilowatt compact power system module must be connected to one shunt module. Each package, which comes in two sizes, includes a fuse and a terminal block. A 230/115V AC cooling fan is provided in the 3600W package. All the 1394 shunt modules have a resistance of 4 ohms. Additionally, all the shunt modules possess agency certifications, such as UL-listed, CE-marked, and CUL-listed.
Circuit Breakers
Circuit breakers, as well as fuses, provide some benefits for the drive system but do not satisfy safety needs completely. Circuit breakers are unable to handle a large inrush current. There is a need to safeguard the 1394 system with the help of a device that possesses a short circuit interrupt current rating of up to 100000 amperes. Supplementary circuit safety equipment, such as the 1492 series, may be utilized as the sole 1394 branch circuit safety equipment if an upstream circuit safety device is rated for the overload current and short circuit ratings. The fully rated instrument let-through must be below or equivalent to the 10 kiloamperes of the 1492's interrupt rating.
Motors (1326 AB)
These highly efficient, medium-inertia, 3-phase servo motors have a unique casing that shortens the length of the motor. They come with steady torque levels ranging from 2.3 to 53.0 N-m. When utilized in conjunction with an oil seal kit, an IP65 protective rating is normal.
Motors (1326 AS)
Neodymium boron iron permanent magnet rotors, which provide small inertia and maximum acceleration, are a hallmark of this family of highly efficient servo motors. They come with continuous torque levels ranging from 0.49 to 49.3 N-m. For a shaft oil seal, an IP65 safety rating becomes necessary for these motors.
Motors (1326 AH)
UL-recognized AC brushless servo motors make up this series of hazardous-duty motors. The motor has a rectangular frame that is entirely enclosed and non-ventilated. It also has a magnet rotor and static winding. High performance is also guaranteed via the use of permanent earth magnets, as well as ever-lasting ball bearings. The continuous torque ratings of these products range from 2.97 to 16.9 N-m.

Four analog outputs, four drive-enabled outputs, and four drive-fault inputs are all offered with the 1394-DIM. The 1394 drive interface module enables any exterior drive with quadrature encoder output. A maximum of four drives may be supported by each 1394-DIM. The 1394x-SJTxx-A is incompatible with the 1394 drive interface module. The impedance of this module is 220 ohms. It has an approximate weight of 3 kilograms. The relative humidity suitable for this module is 5 to 95 percent. The resolution of the module is 12 bits.
Human Interface Module
The 1201-series HIM and SCANport interface of the 1394 analog-servo controller allows for simple setting up and programming. The fundamental operating procedures and protocols of this interface are identical to those employed with different drives. The Human Interface Module serves three basic purposes, which include giving the user a way to program the drive, observe operational conditions, and regulate drive functionalities. There are three different Human Interface modules, which include the 201-HA1, 1201-HA2, and 1201-HAP.
Environmental Regulations
1394 servo controllers must be placed in a clean, dry environment. The surrounding area should have temperatures ranging from 0 degrees Celsius and 50 degrees Celsius to not damage the product. Additionally, the humidity range suitable for 1394 servo controllers with no condensation is 5% to 95%. These products operate at elevations of up to 1000 meters.
