Chassis ground is used to connect the drive chassis to a common ground.
The motor frame must also be connected to the same common ground.
Either earth ground or the ground of the building system must be used.
Refer to the motor manufacturer’s guidelines for additional information.
+ DC, - DC
DC bus terminals are reserved for the 1336 dynamic brake option. Refer to
the 1336 dynamic brake option instructions for installation and connection
details.
M1, M2, M3
Connect the motor leads to these terminals.
!
ATTENTION: A hazard of potential damage to drive output
power components exists if there is insufficient load inductance to
permit the drive short circuit protection function to be effective.
Sufficient load inductance is provided by one of the following:
•
Load reactors of 10mH connected to each motor lead.
•
Motor leads with a minimum length of 40 feet (12.2 meters)
between the drive and the motor.
