Possible faults and solutions of Rockwell AB inverter
Common faults of AB frequency converters
Cause: No output voltage was sent to the motor.
Remedy: Check the power supply circuit, such as the power supply voltage, all fuses and circuit breakers, check the electric ticket, check whether the motor is properly connected, the control input signal, and the start signal is present. Whether I / O terminal 01 is activated, check whether P036 matches the configuration. Check if A095 is not prohibited from turning.
Common faults of AB inverters 2. AB inverters cannot start from the start or operation input sent by the terminal block connection cable
The drive is faulty. The remedy for this kind of cause is mainly to clear the fault. Press the stop button, re-point, and set A100 as option 1 "Clear the fault". If A051-A052 is set to option 7 "Clear fault", re-input the digital input signal.
Programming is incorrect. The remedy is to check the parameter settings. Inverter repair
Input wiring is incorrect. Remedy: Correct wiring and / or installation of jumpers.
Common faults of AB inverter III. AB inverter cannot be started from the integrated keyboard
The integrated keyboard is not enabled. Set parameter P036 to option 0, set parameters A051 to A052 to option 5, and activate the input.
The "Stop" input signal of I / O terminal 01 does not exist. Wire and / or install jumpers properly.
Common faults of AB inverters 4. AB inverters do not respond to speed commands
No speed is given in the speed command source. Check parameter D012 to see if the control signal source is correct. If it is an analog input, check the wiring and use a meter to check whether the signal exists. Check parameter D002 and check if the command is correct.
An incorrect reference signal source was selected via a remote device or digital input. Check parameter D012, check parameter D014 to see if the input selects AC power. Check the settings of A051-A052. Check the source of the speed reference in P038. Reprogram if necessary.
Common faults of AB frequency converters 5. AB frequency converter motor and / or frequency converter cannot accelerate to the command speed
Causes and measures:
The acceleration time is too long. Reprogram parameter P039 or A067.
The extra load or too short acceleration time causes the frequency converter to reach the current limit, thereby slowing down or stopping acceleration. Compare D003 and A089 to remove extra load or reprogram parameter P039 or A067. Check if | A084 is set incorrectly.
The speed command source or value is not the expected value. Check whether the speed commands of D002 and D012 are appropriate.
The output of the frequency converter is prevented from exceeding the limit value by programming. Check P035 to ensure that the speed is not limited by programming.
Common faults of AB inverters
Causes and measures:
Motor input data is incorrect. Enter the motor nameplate data into P031, P032, and P033 correctly. Enable A097 and use A084 to reduce the boost voltage.
AB inverter common faults VII: AB inverter cannot make the motor run in reverse
Digital input is not selected for reverse control. Check digital input X. Select the correct input and program for the reverse run mode.
Digital input wiring is incorrect. Check the input wiring.
The wiring of the reverse motor is not properly phased. Swap the two wires of the motor.
Reverse is prohibited. Check A095.
