3-8 Installing the Converter
590D DC Digital Converter - HA467078
Auxiliary Supply (D7, D8)
Connect the auxiliary or control supply (single phase 50/60Hz)
to terminals D7 (Neutral) and D8 (Line) with suitable external
fuse protection. The steady state current absorbed by the
controller is nominal, the external fuse is determined chiefly by considering the contactor
holding VA and the controller cooling fans.
Field (D3, D4)
Connect the motor field (-) to terminal D3 and field (+)
to terminal D4. If the motor has no field connections, is
a permanent magnet motor, or if the field is derived
externally, you must inhibit the FIELD ENABLE
parameter.
Motor Armature (A+, 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.
