Calibration and Start-Up
DC590+ DRV Series DC Digital Drive
Armature Current Waveform Check
Because there is no field voltage, the drive conducts full load current through the armature during an AUTOTUNE. You can monitor the armature
current waveform with an oscilloscope to verify correct operation of the controller. Attach the oscilloscope leads to the Armature Current test point and
the Sig. Ground test point. Refer to Chapter 7: Test Points for the drive's test point locations. At full rated current, the armature current signal (IA)
should average 1.0 volts since 1.0 volts equals 100% current. There should be six current pulses per mains cycle at all times. The pulses should be
uniformly shaped and evenly spaced, each with a width of 2.8 mS on 60 Hertz supplies, and 3.3 mS on 50 Hertz supplies.
Set Up Field Control
NOTE
If the drive is controlling a permanent magnet motor, set FIELD ENABLE to DISABLED and skip this section.
At this point, the drive/motor combination is operating in field voltage control. This section lists the procedure for setting up for Voltage or Current
control. For best performance, set the field to Current control.
1.
Give a 0% speed demand to the drive.
2.
Start the drive. Measure the field voltage with a DC voltmeter and verify that it matches the motor nameplate rating. Measure the motor field
current with a Hall effect current meter or a current shunt. If the motor field voltage or current is incorrect, follow the steps below to set in the
correct field supply.
WARNING
Failure to set up the field supply correctly can cause dangerous overspeed conditions resulting in serious
equipment damage or injury to personnel. Do not continue the start up procedure until the DC field supply is within
its required rating.
