Why GE DC Drives motor will not brake?
If your GE DC Drives motor won't brake, it could be due to incorrect settings in the brake parameters or excessively short ramp-down times. Check parameter group B-0# DC brake and F-5# Extended Reference.
What to do if the motor is not running on my GE Controller?
If your GE Controller's motor isn't running, start by checking the service switch and motor connection. Ensure line power is applied, especially if you're using a 24 V DC option card. If the keypad stop is active, press [Auto] or [Hand] to start the motor, depending on the operation mode. Also, verify that a valid start signal is applied and that the motor coast signal is not active by applying 24 V on the appropriate terminal or programming it to No operation. Finally, ensure the correct reference signal source is programmed, checking F-02 Operation Method and parameter C-05 Multi-step Frequency 1 - 8 for correct wiring and scaling of terminals and the reference signal.
Why is the display on my GE Controller intermittent?
If you experience intermittent display issues with your GE Controller, it might be due to an overloaded power supply (SMPS) caused by improper control wiring or a fault within the adjustable frequency drive. If the display stays lit briefly, inspect the control wiring for shorts or incorrect connections. If the display continues to cut out, follow the troubleshooting steps for a completely dark display.
What causes a line power current imbalance on a GE Controller?
If the line power current imbalance is greater than 3% on your GE Controller, it could indicate a problem with the line power. Try rotating the input power leads into the adjustable frequency drive one position: A to B, B to C, C to A. Alternatively, the issue might stem from the adjustable frequency drive itself, and rotating the input power leads as described above can help resolve it.
Why is my GE Controller motor running in the wrong direction?
If your GE Controller's motor is running in the wrong direction, the cause may be related to the motor rotation limit, an active reversing signal, or incorrect motor phase connection. Program the correct settings to adjust the motor rotation limit. Deactivate any active reversing signals. Refer to section 3.5 in this manual to check the motor rotation.
Why is the display on my GE af-600 fp intermittent?
An intermittent display on your GE DC Drives could be due to an overloaded power supply (SMPS) caused by improper control wiring or a fault within the drive. If the display stays lit, check the control wiring for shorts or incorrect connections. If the display continues to cut out, follow the procedure for a dark display.
How to troubleshoot motor current imbalance greater than 3% in GE af-600 fp DC Drives?
If the motor current imbalance is greater than 3% in your GE DC Drives, it could be due to a problem with the motor or motor wiring. Check the motor and motor wiring. If the imbalanced leg stays on the same output terminal, it indicates a problem with the drive unit, and you should contact your supplier.
Why GE af-600 fp motor is not reaching maximum speed?
If your GE DC Drives motor isn't reaching its maximum speed, the frequency limits might be set incorrectly. Program the correct limits. Also, the reference input signal may not be scaled correctly; program the correct settings.
How to reduce acoustic noise or vibration from GE Controller?
If you are experiencing acoustic noise or vibration with your GE Controller, like a fan blade making noise at certain frequencies, it could be due to resonances in the motor/fan system. Check if the noise and/or vibration have been reduced to an acceptable limit. You can also turn off overmodulation in F-38 Overmodulation, change the switching pattern and frequency in parameter group 14-0*, or increase Resonance Dampening in H-64 Resonance Dampening.
What causes a GE Controller motor to run rough?
If the motor runs rough on your GE Controller, it might be due to over-magnetization. Check the motor settings in parameter groups P-0# Motor Data, P-3# Adv Motor Data, and H-5# Load Indep. Setting.
