3.5 Full Load Operation Issues
When having issues running the car with a full weight capacity loaded in, a zero-speed test can help
isolate the issue. Set the inspection speed to 0 FPM and command a run - observe for a rollback in either
direction.
Follow these steps to resolve the full load operation issues:
Geared Machines:
Set the motor RPM close to the synchronous speed (no slip).
Magnetek:
- Adjust (A0) -> Motor (A5) -> Rated Motor Speed -> set the RPM close to the synchronous
speed.
Example: if the synchronous speed of the motor is 1800, setting the Motor RPM parameter to
1800 will result in Setup Fault 1. Any value less than 1800 (factoring in some slip) will work.
Observe the motor current under Power Data (D2). Note down the motor current before and
after making the RPM adjustments.
KEB:
- Basic Setup -> Contract Speed (US06) -> set the RPM close to the synchronous speed.
Gearless Machines:
Check if the encoder is functioning correctly. Re-align the encoder (See the Drive Specific Manual for
detailed instructions). If the encoder is functioning well, follow these steps:
Magnetek:
- Adjust (A0) -> Drive (A1) -> Response -> increase the value from the default (10).
- Adjust (A0) -> Drive (A1) -> Speed Dev Time -> decrease the value from the default (0.5).
- (Only if faulty with speed deviation)
- Adjust (A0) -> Drive (A1) -> Speed Dev Fault Level -> decrease the value from the default (25).
KEB:
- Control Setting -> Pre-torque (LC05, LC10) & Acceleration (LC03, LC08, LC11)-> increase
gains for the Pre-torque and Acceleration.
