8.16 VPM Voltage Protection Module
The Voltage Protection Module (VPM, voltage limiting module) is used with per-
manent–magnet induction motors with EMF of 580 V
eff
to 1.4 kV
eff
to limit the
DC link voltage at the converter in the event of a fault. If the line voltage fails at
maximum motor speed or if the drive converter pulses are canceled as a result
of the power failure, the synchronous motor regenerates at high voltage back
into the DC link.
The VPM detects a DC link voltage that is too high (>820 V) and short–circuits
the three motor supply cables. The power remaining in the motor is converted to
heat via the short circuit between the VPM and motor cables.
