Parameter Setting and Functions
5.4.4 Backlash Compensation
This parameter can be set to compensate for positioning offset caused by the backlash of gears.
Specify the direction for compensation with the sign and the quantity of the compensation with a numeric
value. If the sign is positive, compensation will be applied for forward positioning. If the sign is negative,
compensation will be applied for reverse positioning. If the setting is changed, the new setting will be enabled
from the next positioning.
When using an incremental encoder, the final direction used in homing generally serves as the reference direc-
tion and backlash compensation is applied in the opposite direction.
When using an absolute encoder, the initial direction of movement generally serves as the reference direction
and backlash compensation is applied in the opposite direction.
Even when compensation is applied, the compensation will not be indicated in the target position monitor or
any other monitor values. Only the actual motor positions will be subject to compensation.
5.4.5 Torque Limit
Only the internal torque limit can be used.
