1336 Adjustable Frequency AC Drive Selection Guide
The 1336 Adjustable Frequency AC Drive is a versatile and digitally programmable device used in industrial applications for controlling three-phase induction motors. Its exceptional output voltage and current waveforms make it a popular choice for industries that require precise control, energy efficiency, and torque control in their processes.
1336 AC drive is a microchip-controlled device with higher efficiency. It is developed for regulating a 3-phase induction motor in sensitive industrial usage. The drive generates a 3-phase, PWM, changeable frequency output to provide variable motor speed. For optimal motor performance, the drive output voltage can be changed to meet the motor characteristics as it varies with output frequency.
Optional devices from a Local/Remote Control Panel can be used. It can also be used from Serial Communication Port to configure the drive.
The Serial Communications Port or Programming and Display Panel can be used to communicate various status and fault conditions, depending on the parameters set. The drive performs self-check and load diagnostics every time it is powered on and continues to monitor for potential fault situations while it is in operation. Real-time preventative maintenance can be carried out by monitoring standards even during operation. In case of a fault, the diagnostic codes provide detailed information about the problem and the situation, enabling quick remedial action to restore process control.
1336 adjustable frequency AC drive is manufactured in this way which can be used with a 3-phase induction motor. It has a constant torque. It can also adjust the speed with 150% overload capability, a can be programmed to handle various devices. 1336 drive provides excellent current waveforms and output voltage but caution should be considered when it is needed to apply any inverter to the motor. It is important to know that cooling may not be operational at slower speeds. Prolonged use of the motor at full load torque and low speed may result in overheating and motor damage.
When armature-powered fans are run at rated reduced airflow, motors may overheat. Motors that operate at a speed of more than 125% of their fundamental speed could need special balancing. For a suitable motor size for the specified application, consult the motor manufacturer.
When connecting the 1336 drive to an existing motor, precautions must be taken to avoid overheating. It is advised to test the complete drive train equipment for different limits caused by the 1336's range. A suitable motor size for the application should be consulted with the motor manufacturer to ensure optimal performance and avoid issues.

Features of 1336 AC Drives
Operating Environment:
1336 Adjustable Frequency AC Drives are designed to operate within a broad range of environmental situations. These drives are rated for operation within temperatures ranging from 0 to +40°C for the open rating (heat sink) and enclosed rating (heat sink), and from 0 to +50°C for the open rating (chassis components) and enclosed rating (chassis components). These drives are also rated for operation inside a relative humidity ranging from 5 to 95%, with non-condensing conditions, across all ratings. 1336 AC drives can operate at a maximum altitude of 3,300 ft. (1,000m) without derating. These drives can endure vibrations up to 0.006 inches (0.152 millimeters) movement and 1G peak, ensuring reliable operation in various applications. In addition, these drives can withstand a peak shock of 15G for 11ms duration (±1.0mS), making them suitable for use in applications with significant mechanical stress.
Storage Environment:
1336 Adjustable Frequency AC Drives have specific storage requirements to maintain their performance and reliability. These drives should be stored within a temperature range of -40 to +85°C, across all ratings. Furthermore, these drives should be stored in a non-condensing environment with relative humidity ranging from 5 to 95%, across all ratings.
Enclosure:
The specifications related to the enclosure indicated by the catalog number are given below.
- (IP00) Open: All Ratings
- (IP20) NEMA Type 1: All Ratings
- (IP56) NEMA Type 4: B003-B030 & C003-C030
- (IP54) NEMA Type 12: B003-B200 & C003-C200
Input Power Conditioning:
1336 Adjustable Frequency AC Drives are manufactured to be directly connected to a correctly rated, 3-phase AC power line. Though, power line conditions can lead to input power element malfunctions. To prevent these issues, a transformer which an isolation type may be mandatory. The need for a transformer is determined by the presence of power factor correction capacitors in the AC line, and the frequency of transient power interruptions or significant voltage spikes. These drives feature an MOV (a short form of metal oxide varistor) circuit that allows for surge suppression, but it is not designed for constant operation. In an improperly grounded distribution network, the phase-to-ground link of the MOV (metal oxide varistor) might become a nonstop current pathway to the ground, leading to potential damage. To prevent this, line-to-ground and line-to-line voltages must not surpass specified MOV ratings.
Essential Control Inputs:
Five control inputs are needed to operate the 1336 drive:
- The start push button on the control panel, the operator-supplied N.O. contact, or a start push button connected to the optional Logic Interface Board or Remote I/O Interface Board are all examples of "True" inputs that can be used to start the drive.
- The stop button on the control panel, a user-supplied kept connection or stop button linked to the optional Logic Interface Board, a stop signal called the Remote I/O Interface Board, or another source can all supply the drive with the stop input, which is a brief false input that stops the drive.
- An enable input that enables the driver to start, run, or jog can be either a sustained closed contact or a kept True input.
- To provide the Speed Reference input, which controls the drive operating frequency, the optional Logic Interface Board can be connected to a speed potentiometer on the Control Panel, a remote speed potentiometer, an analog signal, a pulse train input signal, or one of the preset speed signals.
- The Auxiliary input, which can be a sustained True input or a sustained closed contact that enables the drive to start, run, or jog, is connected to the Main Control Board or the optional Logic Interface Board.
Optional Control Inputs:
Optional control inputs for operating the drive in reverse, jogging at a pre-programmed speed, choosing between two-speed reference sources, and switching between two acceleration/deceleration rates that have been internally programmed are all available. The control panel, the G2 Remote I/O Interface Board, or the L1, L2, or L3 Logic Interface Board are all options for these optional inputs.
In other words, these optional control inputs provide additional ways to control the motor drive beyond the minimum required inputs. They allow the motor to operate in reverse, jog at a specific speed, switch between different speed reference sources, and switch between different acceleration/deceleration rates. These inputs can be connected to different control devices, such as the control panel or logic interface boards.
