Motor Start/Stop Precautions
ATTENTION: A contactor or other device that routinely disconnects and reapplies the AC line to the
drive to start and stop the motor can cause drive hardware damage. The drive is designed to use
Control input signals that will start and stop the motor. If used, the input device must not exceed one
Operation per minute or drive damage can occur.
Attention: The drive start/stop control circuitry includes solid-state components. If hazards due
to accidental contact with moving machinery or unintentional flow of liquid, gas or solids exist, an
Additional hardwired stop circuit may be required to remove the AC line to the drive. When the AC
Line is removed, there will be a loss of any inherent regenerative braking effect that might be present
- the motor will coast to a stop. An auxiliary braking method may be required.
I/O Wiring Recommendations
Important points to remember about I/O wiring:
•Always use copper wire.
•Wire with an insulation rating of 600V or greater is recommended.
•Control and signal wires should be separated from power wires by at least 0.3 meters (1 foot).
Important:I/O terminals labeled “Common” are not referenced to the safety ground (PE) terminal and are
designed to greatly reduce common mode interference.
ATTENTION: Driving the 4-20mA analog input from a voltage source could cause component
damage. Verify proper configuration prior to applying input signals.
