AC Drives

About This Guide

This procedure is a supplement to and to be used in conjunction with the Installation and Operation Manual for the SP500 Manual for the SP500 AC Controller I/M D2–3304–1. The procedure is meant to explain and condense the installation and operation manual to the basic and most used applications.

Hardware

Drive Protection

Input Voltage and Motor wiring should be sized in accordance with NEC/CEC and all other local codes. Input fuses should be provided to meet NEC/CEC and all other local codes. Suggested protection is a fused disconnect as described in Section 3.7 of the I/M.

Wiring

Three–phase incoming AC shall be wired to terminals R, S and T (as shown in figures 1 & 2). Single–phase AC shall be wired to terminals R and S. AC input wiring, motor wiring and control wiring should be run in separate conduits. Drive chassis ground and motor frame ground wires should be tied to earth ground.

Figure 2. Power Term 1SU4XXXX and 1SU5XXX Controllers

Power Off

Record drive and motor nameplate information including RPM, FLA and HP. Check the drive and motor wiring, with an ohmeter on the highest scale, for grounds. The ohmeter should read in the Megaohm range or totally open. Check that the incoming AC power is appropriate for the voltage as stated on the nameplate of the drive.

Power On

With motor not wired to the drive, apply power. Drive will go through its own software self–testing procedure for approximately 5 seconds, and then display on the keypad 0.00. At this point you can press the start key on the keypad.

If FL is displayed on the keypad LEDs, check that there is either a wire or motor thermostat connected between terminals 10, 11 (as shown in figure 3).

Turn off power, allow bus storage capacitors to discharge by letting drive sit without power for 5 minutes or check DC voltage on +/- terminals. Check motor wiring for the appropriate voltage. Wire motor to U, V and W (as per figure 1 and 2.)

Running the Drive

With motor disconnected from the mechanical load, reapply power and run the drive. With the drive in the local mode (from the keypad), remote led off, press start key and observe motor rotation. If motor rotation is incorrect, turn off power and let bus caps discharge as above, change any two motor leads (at U, V and W).

Run motor up and down the speed range by pressing up/down arrow keys. Connect motor to mechanical load and run drive throughout speed range. Check monitor rpm, percentage load and voltage using mode/enter key. Check calculation in software section for function F–14 motor thermal overload.
Quick start–up is complete.

If the application requires remote start/stop or analog speed reference read Section 5.0 Adjusting the Values of Drive Functions and Typical Wiring Diagrams, Section 3.0 Installation and Wiring.

Software

For most local applications default values are acceptable as listed on the attached parameter list.

To Change Parameters

• Press stop/reset key to stop the drive.
• Press mode/enter key, Program LED should light.
• Press up/down arrow key until desired function.
• Press mode/enter button which display value within function.
• Use up/down keys to change parameter content.
• Press mode/enter button.
• Press stop/reset button to exit programming mode.

To View and Clear Error Log

• Press stop/reset key to stop the drive.
• Press mode/enter button to enter program mode.
• Use down arrow key until Err is displayed.
• Press mode/enter keys to scroll through errors.
• Press stop/reset key to clear faults.

Possible Faults

HU D–C high bus voltage condition

LU D–C low bus voltage condition

OL Electronic thermal overload

OH Controller high temperature

OC Overcurrent, short circuit protection

FL External function loss

Important Parameters to Check

F–00 Control source select (0=local, 1=remote control–terminal speed reference, 2=remote start/stop with keypad speed reference, 3=remote tb start/stop with tb multi–speed presets)

F–01 Accel time 0.5-30 seconds

F–02 Decel time 0.5-30 seconds

F–03 Minimum speed

F–04 Maximum speed

F–05 Current Limit

F–08 RPM scaling at abase speed (whatever you want display to read when drive reaches F–07)

F–14 Elect thermal overload = (motor overload fla/drive output fla) x 100

Monitoring Speed, Current, Voltage, Percent Speed Reference

While drive is running press mode/enter key until desired LED is lit. RPM LED displays output speed scaled by whatever is in function F–08. Percentage Load LED displays percentage of controller fl output amps. Voltage LED displays motor output voltage. With F–13 set to on, all these LED’s lit, displays remote reference percentage
