Electrical Installation
Safety input RFE
(Rotation enable)
Warning!
If the input of the enable or of the rotating field enable are switched off, the
drive is free of torque. The drive could move if there is no mechanical brake or
block provided.
The motor conductors are not dead. Only the rotating field is disabled. Prior to
any work or maintenance on the motor or servo-drive, the servo-drive must be
completely disconnected from the mains power supply.
Operation with RFE input
Two-channel disable of the enable via a safety
switching device.
Enable input FRG/RUN + rotating field enable
input RFE.
Switching-on
Contacts of the safety device closed: enable
FRG/RUN 0.5s after RFE.
Safety switch-off
Contacts of the safety device open:
- there is no FRG/RUN signal in the 1
st
disable
channel to disable the PWM pulses
in the processor,
- there is no RFE signal in the 2
nd
disable
channel to disable the PWM pulses at
the output of the processor.
Restart
Release the safety switching device.
Contacts of the safety device closed.
The motor can only move after a second
disable FRG/RUN (after the rotating field
enable).
Operation without RFE input
The input RFE must be bridged with the logic
voltage.
If the logic voltage corresponds to the supply
voltage, the RFE input is bridged with +24V.
Enable FRG/RUN at least 0.5s after the RFE
signal.
