AC Tech Drive Faults

[machine_problems]

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 Faults

This 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.

Pressure cleaning plays a vital role in improving the appearance and appearance of garages and garages. Consistent cleaning washes away grime, dirt, and trash, boosting the overall appearance and safety of these areas. A clean parking area provides a positive impression for visitors and customers, reflecting well on the establishment or business. Additionally, cleaning trash and stains can prevent wear to the surface and increase its durability. Tidy and kept up parking areas are also not as likely to attract pests and vermin. By utilizing power washing, property owners may guarantee that their parking facilities stay welcoming, secure, and in optimal state.  If you are interested, please visit my domestic and corporate high-pressure washing services website to find out more.
