Operating the Drive 4-13
DC590+ Series DC Digital Drive
Step 9.2 Externally Supplied Field: (not available on Frame 1 units)
Refer to Chapter 3: “Installing the Drive” - Motor Field Options for conversion details.
• Check the voltage applied (externally fused) to terminals FL1 and FL2.
• Check the phasing of voltage applied to FL1 and FL2:
¾ FL1 must be connected directly or indirectly to the Red phase on main power terminal L1.
¾ FL2 must be connected directly or indirectly to the Yellow phase on main power terminal L2.
• The FIELD ENABLE should be set to ENABLE.
• With the FIELD ENABLE parameter in view, press the (DOWN) key. The display changes to FLD CTRL
MODE. Press the M key. Is this set to VOLTAGE CONTROL or CURRENT CONTROL?
¾ If set to VOLTAGE CONTROL, check the value of the FLD. VOLTS RATIO parameter. Set this to 65% to
obtain 300V fields from 460V supplies.
¾ If set to CURRENT CONTROL, check the field current calibration set-up, refer back to “Calibration”.
Check that 3-phase is applied to terminals L1, L2 and L3.
Step 10: Check the Keypad
Check that the HEALTH and RUN Keypad LEDs are now illuminated, also either the FWD or REV LED.
Step 11: Check the STANDSTILL LOGIC parameter
If the STANDSTILL LOGIC parameter in the STANDSTILL menu at level 2 is ENABLED, temporarily set it to
DISABLED.
Caution
During the following set-up instructions, be ready to STOP the drive should the motor try to overspeed.
If 5% speed (approximately) is exceeded and the motor continues to accelerate a reversed connection is implied, decrease the MAIN CURR.LIMIT
parameter to zero. Open the main contactor and disconnect all supplies. Reverse the motor connections.
