structure
4.01
Current magnitude
{di08, 0.43}
Bit SP
Coding
Range ± DRIVE_CURRENT_MAX A
Update rate 4 ms write
The current feedback signal is derived from internal current transformers. It is used for current control and indication of the armature current, and to
initiate motor protection.
4.02 Filtered current magnitude
Bit SP
Coding
Range ± DRIVE_CURRENT_MAX A
Update rate 4 ms write
The value of the current magnitude parameter filtered over the last 6 mains cycles.
4.03

Torque demand

{di07, 0.42}
Bit SP FI
Coding
Range ±TORQUE_PROD_CURRENT_MAX %
Update rate 4 ms write
The torque demand can be derived from the speed controller and/or the torque reference and offset. The units of the torque demand are % of rated
torque.
4.04

Current demand

Bit SP
Coding
Range ±TORQUE_PROD_CURRENT_MAX %
Update rate 4 ms write
The current demand is derived from the torque demand. Provided the motor is not in current limit, the torque and current demands are the same and
the drive is not operating in the field weakening region.
4.05

Motoring current limit

Bit SP
Coding
Range 0 to MOTOR1_CURRENT_LIMIT_MAX %
Default 150.0
Second motor
Pr 21.27
parameter
Update rate Background read
The motoring current limit applies in either direction of rotation when the machine is producing motoring torque.
4.06

Regen current limit

Bit SP
Coding
Range 0 to MOTOR1_CURRENT_LIMIT_MAX %
Default 150.0
Second motor
Pr 21.28
parameter
Update rate Background read
The regen current limit applies in either direction when the machine is producing regenerating torque.
