Overview
The voltage protection function is deployed on 1FE 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 residual motor energy is converted to heat via the short
circuit in the VPM and motor.
■
Integration
The VPM can be operated in conjunction with SINAMICS S120,
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). Shielded
6FX8 motor feeder cables must be used when a VPM is installed.
Requirements for operation of 1FE/2SP1 motors
with SINAMICS S120:
•
SINAMICS S120
•
SINUMERIK 840D sl, SW version 1.3 and higher
