Motor Field Connections; Internal/External Supply (Frames 2, 3, 4 & 5) - Parker 590+ DRV Product Manual

AT ZERO SPEED – When the drive speed feedback drops below the zero speed threshold, terminal B5 will output 24 VDC.
DRIVE HEALTY – When there are no software or hardware alarms and terminal C3 (RUN) is ON or when C3 is OFF, terminal B6 will output 24
VDC. This is the unlatched health signal in the drive.
DRIVE READY – When there are no software or hardware alarms and terminal C3 (RUN) is ON, terminal B7 will output 24 VDC
Jog (C4)
JOG
This is a one-button function for positioning the motor at a pre-determined speed.
Ramp Hold (C7)
DIGIN 2
When 24 VDC is connected to C7, the ramp speed setpoint (terminal A4) is held at its last value. When the 24 VDC is removed, the ramp continues to
the setpoint from terminal A4.
Technology Box Option (H1 - H6)
When the option is fitted to the drive, it provides terminal block H which allows drives to be connected together to form a network.
Refer to the appropriate Technical Manual supplied with the Technology Box.

Motor Field Connections

The FIELD CONTROL function block controls the motor field. The FLD CTRL MODE parameter allows you to select either Voltage or Current
Control mode.
• In Voltage Control mode, the FLD.VOLTS RATIO parameter is used to scale the motor field output voltage as a percentage of the input supply
voltage.
• In Current Control mode, the SETPOINT parameter is used to set an absolute motor field output current, expressed as a percentage of the calibrated
field current (IF CAL).
Internal/External Supply (Frames 2, 3, 4 & 5)
NOTE
The Frame 1 unit uses only an internal motor field supply. The Frame 7 unit uses only an external motor field supply. For information about
the following terminal/power boards refer to Appendix E: "Technical Specifications" - Power Board Types, and Terminal Information
(Power Board).
The internal motor field is more widely used, however, there is provision on the unit for an external motor field supply to be connected (perhaps for
where the field voltage is greater than the input voltage and therefore not attainable, or where the motor field is switched separately for convenience).
DC590+ DRV Series DC Digital Drive
WARNING
Isolate the drive before converting to internal/external supply.
