Running friction compensation parameters
When the motor runs stably, the output torque is used for material tension and
consumed by rotation friction. If the rotation friction consumes large output torque,
compensation for the output torque is required.
Para. Name De

Value Range
Description
B1‑07
Friction force
compensation
coefficient
0.0% 0.0% to 50.0%
In tension control mode, the AC
drive automatically sets the target
torque according to the tension
reference and roll diameter. The
target torque is increased
(winding)/decreased (unwinding)
according to B1‑07 to offset the
effect of friction on material
tension.
This parameter corresponds to the
percentage of the rated torque of
the AC drive.
B1‑17
Friction force
compensation
correction
coefficient
0.0% ‑50.0% to
+50.0%
In most scenarios, friction may vary
with running frequency. Using B1‑
07 may not achieve ideal friction
compensation effect. To achieve
better effect, use B1‑07 together
with B1‑18. See B1‑18 for details.
This parameter corresponds to the
percentage of the rated torque of
the AC drive.
