| 12/13/2002 | The AC drive repeatedly displays an OV (Overvoltage) fault when the inverter is stopping. What causes this? | |
| 12/13/2002 | The J7 drive will only allow the parameter to viewed but not changed.
What must be done to change parameter values in the J7/305 AC drive? | |
| 01/16/2003 | C21 unit is connected and runs in Hand and Auto fine. But, the input circuit breaker is tripping while attempting to run in Bypass mode. Why? | |
| 07/13/2004 | The E7L will not run the motor in Hand or Auto mode.
--OTHER SYMPTOMS:
1. Drive LED flashes.
2. Stop LED is lit.
3. Contol Power LED is lit.
4. No Ready LED.
What can cause this? | |
| 07/13/2004 | The V7 Drive Jog Reference (S7) command is given. Why doesn't the motor move? | |
| 07/13/2004 | The GPD 515/G5 displays a parameter, but does not let me change it. Why? | |
| 07/13/2004 | On the GPD 515/G5, If Terminal 1 to 11 are closed, but the GPD515/G5 inverter still does not run. What is wrong? | |
| 07/13/2004 | What is the purpose of a softcharge resistor and contactor in a GPD506 / P5 drive? | |
| 07/13/2004 | Serial communication is lost intermittently between the building automation system (BAS) and a Lonworks board on the GPD506 / P5 drive. What might be causing this? | |
| 07/13/2004 | The P5/GPD506 inverter is displaying an "OH2" fault that will not clear. The heat sink fan(s) is running, and the drive is cool. Why won't it clear? | |
| 11/29/2005 | The P5/506 bypass panel "Fault" light is ON, but no fault code is shown on the keypad display. What's wrong? | |
| 07/15/2004 | C21 unit is connected and runs in Hand and Auto fine. But, the input circuit breaker is tripping while attempting to run in Bypass mode. Why? | |
| 07/13/2004 | A Siemens Apogee FLN option board is installed on GPD506 bypass drive so a run command can be initiated through network communications. After a safety circuit fault has been reset, the drive will not run again even though it has been commanded to. Why is this happening? | |
| 06/08/2007 | The Drive Wizard .PARMS file was edited with another program (ie. Microsoft Word, Notepad) and saved. When reopened with DriveWizard, an error code of "File Error" was displayed on-screen. What is the problem and how can this be corrected? | |
| 07/13/2004 | When entering Motor Rated Current (parameter E2-01) into an E7 drive, an OPE02 fault appears on the display. What can cause this, and how is the fault cleared?
| |
| 07/13/2004 | When the E7 drive trips out on a fault it must be manually reset. Can the E7 be set to restart automatically after a fault? | |
