SIMOTICS M synchronous motors for SINAMICS S120
VPM Voltage Protection Module

■
Overview
The voltage protection function is deployed on 1FE1 motors and
on the synchronous version of 2SP1 motor spindles with an EMF
of
Û
> 820 V to 2000 V (
U
rms
570 V to 1400 V) in order to limit the
DC link voltage in the drive system in the event of a fault.
If the line voltage fails with the motor operating at maximum
speed, or if the drive system pulses are suppressed as a result
of a line voltage failure, the synchronous motor feeds energy at
high voltage back into the DC link.
The VPM detects that the DC link voltage is too high
(DC > 820 V) and shorts the three motor feeder cables in order
to brake the motor. The power remaining in the motor is con-
verted to heat via the short circuit in the VPM and motor.
■
Integration
The VPM can be operated in conjunction with SINAMICS S120,
and with 1FE motors and with 2SP1 motor spindles.
The VPM must be installed between the motor and drive system
(maximum distance from drive system 1.5 m (4.92 ft)). 6FX8
shielded motor supply cables must be used in combination with
the VPM.
System requirements for operating 1FE motors and 2SP1 motor
spindles with SINAMICS S120:
•
SINAMICS S120
•
SINUMERIK 840D sl from SW version 1.3 and higher
