Connect the
motor
armature to
terminals A+
and A-.
The motor armature is connected to busbar terminals
A+ and A-. If a DC contactor is used the poles should
be interposed between the controller terminals and the
motor terminals.
Note:
When the controller is operating in a
regenerating mode for extended periods
acting as a load generator for another
machine, it is advisable to fit additional
protection in the armature circuit. A DC
fuse or a high speed circuit breaker will
provide this protection, if in doubt consult
the Parker SSD Drives Engineering
Department.
