Command Value Processing in Torque/Force Control

Filtering the Command Value

Additive Current Command

DOK-INDRV*-MP*-02VRS**-FK01-EN-P

• torque/force control with regard to the sum of the command values

preset in parameters S-0-0080, Torque/force command value and

S-0-0081, Additive torque/force command value

• The torque/force command value is generated internally by the velocity

loop. The value of parameter S-0-0081 can be added to this command

value as an additive component.

• limitation of the preset command value to limit value that can be

parameterized

• filtering the command value by means of parameter P-0-0176,

Torque/force command smoothing time constant
