Motor velocity feedback value
Viscous friction compensation value
The actual compensation value of viscous friction can be calculated as follows:
Viscous friction compensation torque = rated torque of motor × [friction torque viscosity coefficient value]/1000 × actual
speed of motor/rated speed of motor

How to use
1.
Byte2 of the parameter [torque control switch] is used to control the enabling of static balance torque compensation.
When it is set to 0x00, compensation is disabled; when set to 0x01, manual static balance torque compensation is enabled;
when set to 0x02, automatic static balance torque compensation is enabled.
2.
When manual static balance torque compensation is selected, the user shall set the appropriate [manual static balance
torque compensation value] (0x20DA) before the servo is ON according to the actual working conditions.
3.
When automatic static balance torque compensation is selected, the servo drive will automatically calculate the
compensation value, and the user can adjust the compensation value by using the parameter [Auto Static Balance Torque
Compensation Factor] (0x21DA) according to the compensation effect.
When the [static balance torque compensation] function is used, the motor brake control mode shall be
set to [Drive automatic control] or [Mixed control] through the parameter [Motor Brake Control
Setting] (0x2151).
The automatic static balance torque compensation mode is not applicable in some scenarios, such as free
stop during motor movement.
