Defines the offset for the external PID controller output.
When PID controller is activated, controller output starts
from the offset value. When PID controller is deactivated,
controller output is reset to the offset value.
Parameter 4230 TRIM MODE
Value in percent
Activates the trim function and selects between the direct
and proportional trimming. With trimming it is possible to
combine a corrective factor to the drive reference. See
section Reference trimming
No trim function selected
Active. The trimming factor is proportional to the rpm/Hz
reference before trimming (REF1).
Active. The trimming factor is relative to a fixed maximum
limit used in the reference control loop (maximum speed,
frequency or torque).
Defines the multiplier for the trimming function. See section
Reference trimming on page 129.
Selects the trim reference. See section
on page 129.
