What to do if ABB DC Drives line fuse blows?
If the line fuse blows or the circuit breaker trips, it may be due to an incorrect rating of the installed fuse or circuit breaker. Refer to Table 1-4 for the correct rating. Also, inspect the wiring for any looseness or damage.
What to do if ABB DC Drives motor runs then stops?
If the motor runs and then stops after a short time, or if the drive trips due to overload (TCL Fault), you must manually restart the drive by disconnecting and reconnecting the AC power. Additionally, reduce the load on the motor.
What to do if ABB DC Drives motor is not running?
If the motor is not running but the Power On LED is illuminated, check the following: - Ensure the Start-Stop switch is in the START position if this mode is used. - Verify that the Main Speed Potentiometer is not set to zero; adjust it to the desired speed. - Confirm that the Main Speed Potentiometer, signal input, and motor connections are properly connected.
What to do if ABB Baldor BC201 DC Drives logic control board fuse blows?
If the Logic Control Board fuse, F1, blows, inspect the signal or control wiring for shorts or grounds. Verify that the Start/Stop switch, Enable switch, and Speed Adjust pot are operating correctly and are not shorted or grounded.
Why is S CL LED indicator illuminated on ABB Baldor BC201 DC Drives?
The S CL LED indicator illuminates for several reasons: - The motor might be overloaded. Check the motor amps with a DC ammeter in series with the armature. If it is a shunt type motor, the field may be open or not receiving the correct voltage. - The motor may have internal shorts or grounds, potentially indicating a defect. - The CL trimpot may be set too low; check its position. - Rapid acceleration changes can trigger the LED. Verify the potentiometer setting.
How to fix ABB Baldor BC201 running at high speed?
If the motor runs at high speed and does not respond to the main adjust speed pot or reference signal, check the field wiring. If you are using tachometer feedback, check the tachometer signal.
Why is power ON LED indicator not illuminated on ABB DC Drives?
If the Power ON LED indicator is not illuminated, ensure that the AC Line connections have been properly made and the wiring is correct. Also, check the AC Line fuse.
