Installation manual of system “bp408” - Commissioning 101
NOTE!
 The electromagnetic holding brake must be switched on and off immediately
via the relay MB. This is the only way to ensure that the inverter can start and
stop smoothly.
 The main contactors to the motor must be switched on and off instantaneously
with the relay RB. This is the only way to ensure that smooth start and stop
are possible.
 If, in the event of a fault, the collective fault relay is triggers on the inverter, the
control system must ensure that the mechanical brake and the main
contactors to the motor are switched off immediately. The collective fault signal
output of the inverter is connected to terminal 34 of the control system.
 With the mains contactor of the inverter, the mains contactor in the control
system must be closed or opened immediately. Only then is it possible to
monitor the brake chopper for overtemperature and to disconnect the inverter
from the mains, if necessary.
8.9.1 Cut-off points for the high drive speed
The braking distance can be found in the diagram. The values indicated are only
valid if the factory setting for the rounding remains unchanged. In addition, it is
assumed that the control system forwards the cut-off points to the inverter
immediately.
The values shown here are guidelines and should be adapted to personal on-site
preferences.
NOTE!
The cut-off point should – if possible – be set to a greater value than the determined
braking distance in order to have a free space for optimising the driving behaviour.
