Digital Brushless AC S ervo D rive system - Ref.1609 ACSD-69/80
Function Time constant of the torque compensation. Before applying
it, it is filtered with a low-pass filter to improve the friction
behavior in velocity direction changes.
The constant friction suddenly changes when changing the
sign of the reference speed. The filters “smoothes” the
compensation torque preventing jerks in the system when
reversing the moving direction and better modeling the
behavior of friction.
Valid values 0.0 (by default), ..., 2 000.0 ms.
TP14 USER, RW S34676 TorqueCompensationTimeConstant
NOTE. With TP14=0, all the friction compensations are
canceled.
