Anyone have a list of AC Tech drive faults? I have a tattered manual, just looking for a better version of the drive faults. i think AC Tech faults are similar on the different drives.
List if AC Tech FaultsThis is a list of some of the AC Tech warnings and status messages. I am working on a list of faults or alarms for troubleshooting and diagnostic purposes. I'm not sure on the scope of which drives these messages applied to, but I believe they match up with many from their catalog.Status Messages (Warnings):
- br: DC-injection brake active Cause: DC-injection brake activated Remedy: Deactivate DC-injection brake, deactivate digital input
- bF: Drive ID warning Cause: The Drive ID (P502) stored on the EPM does not match the drive model. Remedy: Verify motor data (P302. . .P306) and perform Auto Calibration
- CAL: Motor Auto-calibration active Cause: Refer to P300, P399 Remedy: Motor Auto-calibration is being performed
- cE: An EPM that contains valid data from a previous software version has been installed Cause: An attempt was made to change parameter settings Remedy: Parameter settings can only be changed after the EPM data is converted to the current version
- CL: Current Limit (P171) reached Cause: Motor overload Remedy: Icrease P1 71, Verify drive/motor are proper size for application
- dEC: Decel Override Cause: The drive has stopped decelerating to avoid tripping into HF fault
Remedy: If drive trips into HF fault: Increase P1 05, P1 26, or Install Dynamic Braking option
- Err: Error Cause: Invalid data was entered, or an invalid command was attempted Remedy:
- FCL: Fast Current Limit Cause: Overload Remedy: Verify drive/motor are proper size for application
- FSt: Flying Restart Attempt after Fault Cause: P110 = 5,6 Remedy: P110 = 5,6
- OE: OEM Settings Operation warning Cause: An attempt was made to change parameter settings while the drive is operating in OEM Settings mode. Remedy: In OEM Settings mode (P199 = 1), making changes to parameters is not permitted.
- OF: OEM Defaults data warning Cause: An attempt was made to use (or reset to) the OEM default settings (P1 99 = 1 or 2) using an EPM without valid OEM data. Remedy: Install an EPM containing valid OEM Defaults data
- LC: Fault Lockout Cause: Remedy:
- PdEf: PID Deceleration Status Cause: PID setpoint has finished its ramp but the drive is still decelerating to a stop. Remedy: ??
- PId: PID Mode Active Cause: Drive has been put into PID Mode. Remedy: Refer to P200
- SLP: Sleep Mode is active Cause: Refer to P240...P242 Remedy:
- SP: Start Pending Cause: The drive has tripped into a fault and will automatically restart (P110 = 3.. .6) Remedy: To disable Auto-Restart, set P1 10 = 0...2
- SPd: PID Mode disabled. Cause: Drive has been taken out of PID Mode. Refer to P200. Remedy:
- StoP: Output frequency = 0 Hz (outputs U, V, W inhibited) Cause: Stop has been commanded from the keypad, terminal strip, or network Remedy: Apply Start command (Start Control source depends on P100)
Thanks, this is sort of what I was looking for. i would really like to see a list of the F codes that they use.
F_dbF, F_F2, F_F3, F_F4, F_F5, etc.
