Detail Drive Configuration and Operation

Motor Sim Mode

When the motor simulation mode is selected the precharge requirements are
ignored and the precharge done condition is not needed for running the drive.

External Power Supply

If the drive is used with an external power supply, the user should not request a
precharge until the drive incoming power is available. If the user does request a
precharge without incoming drive power a precharge timeout fault will occur (if
configured for a fault).

Note: The default for parameter 838 [DigIn 1 Sel] has changed from the value of
14 “PreChrg/Disc” to 0 (none) in firmware release version 1.17 and later.

Preset Speeds

There are no “Preset Speed” parameters. However, the Speed Reference
parameters can be used as set speeds. See the

Speed Reference

for more

information.

Process PI Loop

The drive has a process PI loop that can be used to trim speed, torque, or some
other function.
