DRIVE RUN Activation at drive start. Start (drive running) = active. 7
ON Activation at drive power-up. Power-up (drive powered) =
active.

TIMED FUNC 1 Activation by a timed function. Timed function 1 active = PID
control active. See parameter group 36 TIMED
FUNCTIONS.

4229 OFFSET 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 must be set to NOT SEL.
0.0%
0.0…100.0% Value in percent 1 = 0.1%
4230 TRIM MODE 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 on page 129.
NOT SEL
NOT SEL No trim function selected 0
PROPORTION
AL
Active. The trimming factor is proportional to the rpm/Hz
reference before trimming (REF1).
1
DIRECT Active. The trimming factor is relative to a fixed maximum
limit used in the reference control loop (maximum speed,
frequency or torque).
2
4231 TRIM SCALE Defines the multiplier for the trimming function. See section
Reference trimming on page 129.
0.0%
-100.0…100.0% Multiplier 1 = 0.1%
4232 CORRECTION
SRC
Selects the trim reference. See section Reference trimming
on page 129.
