Chapter 4 START UP AND ADJUSTMENT
The 590SP 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 590SP (see Chapter 3). Review Appendix 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 590SP 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 your 590SP, make these motor checks before applying power.
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 requiring a series or parallel connection
depending on the supply and torque requirements.
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 through the armature and field:
Armature resistance = 3
W
or less for motors rated 5 Hp or less.
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.
