Current Draw Down with Multi-Motor Drive Operation
When using a PowerFlex 700S drive to run multiple motors, the drive must be
sized in order to provide the total current required to run the connected motors
plus the current required to line start any disconnected motors. If the total
current rating of the drive is not capable of providing the total current described
above, the motor speed may slow, possibly to zero, and re-accelerate the motors
back to the set speed when line starting a disconnected motor.
DC Bus Overvoltage Fault (Fault 24) for High Horsepower Drives
A DC Bus overvoltage fault may occur for high horsepower drives when
executing a flying start within 2 seconds of a commanded stop with no or light
loads.
Homing to a Switch and Then to a Marker Not Functional with DriveLogix
When using the Homing function with a PowerFlex 700S Phase II drive with
DriveLogix, you can either Home to a Switch or Home to a Marker. However,
you cannot Home to a Switch and a Marker in the same command.
Motion Registration Input Limited to Digital Input 1 or Registration Input 0
The Registration input to the drive is limited to Digital Input 1 and Registration
Input 0. Therefore, the RSLogix™ MAR (Motion Arm Registration) instruction
will not function properly if Registration Input 1 is used.
Operating Mode Configuration Parameters Should Not be Changed
The following parameters should not be changed by a user:
•
510 [FVC Mode Config]
•
511 [FVC2 Mode Config]
•
512 [PMag Mode Config]
•
513 [V/Hz Mode Config]
