5.1.1.1 Description about torque verification and brake slip
After the VFD runs, the VFD output current or torque is checked before the holding 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 torque verification time P90.30 is reached, the torque verification fault "tPF" is reported.
