Solutions To Drive Problems<br />
TROUBLESHOOTING<br />
After you display the fault messages, you are ready to try to remedy<br />
the problems.<br />
An easy-to-use chart will help you quickly locate the possible causes<br />
to the problem. It also lists remedies you should try before you call for<br />
service.<br />
¥ The column labeled ÒMessageÓ lists all of the fault messages that<br />
can be displayed on the keypad.<br />
¥ The column labeled ÒPossible CausesÓ lists all of the things that<br />
might cause the message to appear. You will note that some of<br />
the possible causes are listed for more than one message. This<br />
can occur when a situation, such as a conveyor jamming, causes<br />
several situations, such as motor overload and inverter overload,<br />
to occur simultaneously.<br />
¥ The column labeled ÒSuggested RemediesÓ lists the things you<br />
can try before you call for service. Note that you cannot correct<br />
some of the situations yourself. In these cases, Òcall for serviceÓ is<br />
the only option listed.<br />
¥ If you exhaust all of the solutions and still get fault messages, call<br />
<strong>Cutler</strong>-<strong>Hammer</strong> for service.<br />
Refer to the Toll Free number on the back cover of this manual to<br />

Running In Open Loop Test Mode<br />
You might want to run your drive without a motor connected during<br />
troubleshooting (this is called the OPEN LOOP TEST Mode):<br />
1. Apply power to the drive.<br />
2. Press the Operate button, (the Operate LCD is lights).<br />
3. Jumper terminal 7 to 8 and terminal 7 to 15.<br />
4. Press and hold the Operate button and press the Start button.<br />
5. Release both buttons.<br />
In the OPEN LOOP TEST Mode the keypad LCD displays the output<br />
voltage, speed, and frequency. Load and current values should be<br />
zero. Note that if you try to connect a motor to a drive in the OPEN<br />
LOOP TEST Mode, the drive will trip after 5 seconds and display<br />
ÒMotor Fault.Ó The drive will also trip on Motor Fault if you try to run<br />
with no motor connected in the default CLOSED LOOP Mode.<br />
To return to the default CLOSED LOOP Mode, press the Stop button.<br />
