5.9.3 Description about torque verification and brake slip
After the VFD runs, the VFD output current or torque is checked before the brake release. If the VFD
output current or torque is greater than the output current or torque setting (P90.12 or P90.15) and
the situation lasts 60ms, torque verification succeeds. If torque verification does not pass after the
