If the torque offset parameter is specified, be sure to specify the
following parameter also.

TCPCLR(#1) The function for setting a value for canceling the torque offset at an
emergency stop in the velocity loop integrator is:
0: Disabled
1: Enabled
<7> Compensate for dynamic friction.
(i) Method of canceling a dynamic friction in proportion to
velocity
Measure an estimated disturbance value at a constant
velocity. Then, by assuming this measured value as a
dynamic friction, set the proportional coefficient for a
velocity and dynamic friction compensation value.

If the measurement velocity is too high, lower the measurement
velocity, and measure the estimated disturbance value. By
proportional calculation, obtain the estimated disturbance value at the
above measurement velocity.
