BAMOBIL D3.2
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.
