Incredible Network Communications Capabilities
Countless benefits are offered by PowerFlex 70 drives, which are interoperable with a variety of communication adapters. With adapter routing, one can connect a PC to one drive and communicate with all other Allen-Bradley drives on the same network without going via a network scanner. Users have total control over every configuration of the network. When AutoBaud is available, connections are established more quickly. (Unconnected Messaging) enables direct disc interaction without passing via the network scanner for other network devices (like PanelView). When changing a drive, ADR ("Automatic Device Replacement"), which configures a scanner to automatically identify any new drive and download the necessary parameter settings, saves time and effort. Adapters may be configured to communicate user-customizable logic control and speed reference values, as well as to carry out fault-based actions including ramp-to-stop, hold the last state, and coast-to-stop. Additionally, dependent on whether the network had a significant issue (such as a broken cable) or was idle, other measures may be taken (PLC set to "Program"). Depending on the state of a master drive or (consumer), peer control enables one or more slave drives or (consumers) to operate (producer). Additionally, it may considerably lessen network traffic.
Environmental Consideration
The PowerFlex 70 drive can operate at an altitude of up to 1000 m without any derating. Without derating, the maximum temperature of the surrounding atmosphere ranges from 0 to 50 degrees Celsius. However, the temperature ranges from 0 to 40 and 0 to 65 degrees Celsius for the chassis (heatsink) and control, respectively. The temperature range for storage is -40 to 70 degrees Celsius. No volatile or corrosive gases, fumes, or dust should be present around the PowerFlex 70 AC drive. The drive must be stored in a corrosive-free environment if it isn’t fitted for a long time. The drive's permissible relative humidity ranges from 5 to 95 percent.
Programming Parameters

Installation Considerations
Installations of the PowerFlex 70 frequently include adding input fuses or a circuit breaker. Electrical codes and/or national and local industrial safety regulations may place further limits on these systems.
There are a variety of cable types allowed for drive installations. If it is kept away from crucial circuits, the unshielded cable is adequate for many systems. For every 10 meters of length, allow 0.3 meters of space. Wherever possible, long parallel runs should be avoided.
Power Wiring
The PowerFlex 70 includes multiple safety measures to facilitate installation. Ground fault protection enables dependable operation both during startup and operation. Overload-protected electronic motors have a longer motor lifespan. Alternatively, if the drive is linked to a resistive grounded system, an ungrounded system, a B-phase grounded system, or an impedance grounded system, these devices must be unplugged. If the driving power source is a regenerative unit or DC supplied by an active converter, these devices should also be unplugged. Thanks to 6 kV transient protection, the 380–480V system voltages are more durable.
