1. Check and record nameplate information from the motor for future reference.
2. Verify that the motor wiring agrees with the motor installation drawings, if available. Be sure to check
the motor field wiring. Some motors have two winding fields which require a series or parallel connec-
tion depending on the supply and torque requirements. Verify that the drive field supply output does
not exceed the voltage rating of the motor field. If this voltage exceeds the field rating, supply the field
power externally with the correct AC supply (refer to Figure 3.4 or 3.5 in Chapter 3).
3. Use an ohmmeter to check insulation and continuity on the motor's armature and field. Use the follow-
ing as a guide for measuring continuity and resistance through the armature and field:
Armature resistance < 1
W
(about 3
W
for motors rated under 10 HP).
Field resistance = Motor nameplate field voltage
Motor nameplate field current
Insulation checks help ensure that there are no shorts in the motor. Use an ohmmeter set to its highest
setting and measure the resistance between each conductor and ground. All readings should be greater
than 10 M
W . If available, use a megger to check for insulation faults in the motor armature and field
windings.
Chapter 4 START UP AND ADJUSTMENT
The 590 DRV Digital drive is shipped with a default configuration designed to control a shunt or permanent magnet
field DC motor. You can adjust the drive's parameters or change its configuration to achieve optimum performance
and perform specific control applications.
The drive can be tuned or configured using the drive’s MMI, or by using a computer running the software package
ConfigEd Lite. This chapter guides the user through the start up procedure using the MMI.
Follow these procedures only after installing and wiring your 590 DRV Digital drive (see Chapter 3). Review Appen-
dix B to become familiar with the MMI before proceeding.
When an instruction refers to a MMI procedure, the menu levels are shown as a path with double colons “:: ” delimit-
ing each lower menu level, for example:
SETUP PARAMETERS:: RAMPS:: ACCEL TIME
RECOMMENDED TOOLS
Equipment recommended to set up your 590 DRV Digital drive and tune a motor include:
• IBM compatible PC with Microsoft Windows™ 3.0 or greater to run ConfigEd Lite
• Oscilloscope to monitor armature current waveform and speed feedback
• Voltmeter to monitor motor armature and field voltage and check control signal levels
• Ohmmeter to check signal continuity
• Clamp-on, Hall effect ammeter to measure armature and field currents
• Digital hand tachometer to check line or motor speed
WARNING!
Confirm all wiring connections are correct before attempting start up procedures.
CHECK MOTOR
After wiring and installing the 590 DRV Digital drive, make these motor checks before applying power.
