7000-TD002A-EN-P – September 2007
Field Current Command
[Field CurCmd]
Linear Number:
314
Minimum Value:
0.000 pu
Maximum Value: 2.000 pu
Access Level:
Advanced
Read/Write:
Read
Only
This parameter specifies the current command for the synchronous motor field supply. For synchronous
drives, this parameter must be assigned to one of the ACB analog outputs. An analog output of 10.0 V
corresponds to maximum field current, which should be somewhat higher than rated field current. The
scaling of the field current command can be adjusted to match the scaling of the field supply current
reference input using the associated analog output scaling parameter. For induction motors this
parameter is always equal to zero.

Flux Command Limit [Flux Cmd Limit]
Linear Number:
623
Minimum Value:
0.000 pu
Maximum Value: 1.500 pu
Access Level:
Service
Read/Write:
Read
Only
This parameter specifies the maximum value of flux reference which the drive can use. It is a constantly
changing value based on the operating speed of the motor and the input bridge voltage. For most
applications in normal speed range, this value should be greater than
FluxCmd Rated Load
(100). This
parameter is used to prevent the current regulator from hitting advance limits.
PFC Flux Command
[PFC Flux Command]
Linear Number:
304
Minimum Value:
-1.500 pu
Maximum Value: 1.500 pu
Access Level:
Service
Read/Write:
Read
Only
This parameter displays the flux command from the PFC controller needed to optimize the drive input
power factor. The final flux command will be sum of the original flux profile without power factor
compensation and the flux command from the PFC controller. The parameter can have a negative value.
