DC590+ Series DC Digital Drive
Power Connections continued
Motor Field
F-
F+
Connect the
motor field (-)
to terminal F-,
and connect
field (+) to
terminal F+.
Frame 3: Terminals F- & F+ = D3 & D4
Connect the cable screen to the independent earth/ground point.
If the motor has no field connections, is a permanent magnet motor,
or if the field is derived externally, you must either:
disable the FIELD ENABLE parameter (Tag No. 170)
later during Set-up (disables the Field Fail alarm automatically)
or
disable the Field Fail alarm
Motor Thermistor
Th1
Th2
Connect the
motor
thermistor to
terminals Th1
and Th2
or
link terminals
if sensors are
not fitted.
Frames 3, 6 & H: Terminals Th1 & Th2 = THERM1 & THERM 2
Terminals Th1 and Th2 must be linked if motor sensors are not fitted.
(Thermistor terminals for Frames 3, 6 & H are on the Control Door Board).
We recommend that you protect the dc motor against overtemperature by the use of temperature sensitive resistors
or switches in the field and interpole windings of the machine. When the motor is fitted with over-temperature
sensing devices, such as thermostats or PTC thermistors, these should be connected (in series) between terminals
TH1 and TH2.
• Thermistors must have a combined working resistance of 750 or less, rising to 4k at over-temperature.
These thermistors are classified by IEC34-II as Mark A.
• Temperature switches must be normally closed, and open at rated temperature.
The over temperature alarm will activate at 3k. It is latched in software and must be reset by re-starting the Drive.
NOTE The motor temperature alarm (THERMOSTAT) cannot be inhibited in software.
