226
Causes
MFDI terminal DI3 caused an external fault through
an external device.
The wiring is incorrect.
External Fault [H1-03 = 20 to 2B] is set to MFDI
terminal DI3, but the terminal is not in use.
Causes
MFDI terminal DI4 caused an external fault through
an external device.
The wiring is incorrect.
External Fault [H1-04 = 20 to 2B] is set to MFDI
terminal DI4, but the terminal is not in use.
Causes
MFDI terminal DI5 caused an external fault through
an external device.
The wiring is incorrect.
External Fault [H1-05 = 20 to 2B] is set to MFDI
terminal DI5, but the terminal is not in use.
Causes
MFDI terminal DI6 caused an external fault through
an external device.
The wiring is incorrect.
External Fault [H1-06 = 20 to 2B] is set to MFDI
terminal DI6, but the terminal is not in use.
Causes
MFDI terminal DI7 caused an external fault through
an external device.
The wiring is incorrect.
External Fault [H1-07 = 20 to 2B] is set to MFDI
terminal DI7, but the terminal is not in use.
Causes
There was a problem with the EEPROM hardware.
Electrical interference corrupted the data while it
was writing to the EEPROM of the drive.
Causes
The FbH detection level is set incorrectly.
There is a problem with the PID feedback wiring.
The feedback sensor is not operating correctly.
Possible Solutions
1. Find the device that caused the external fault and remove the
cause.
2. Clear the external fault input in the MFDI.
Correctly connect the signal line to MFDI terminal DI3.
Correctly set the MFDI.

cause.
2. Clear the external fault input in the MFDI.
Correctly connect the signal line to MFDI terminal DI7.
Correctly set the MFDI.
Possible Solutions
• Re-energize the drive.
• If the fault stays, replace the control board or the drive.
Contact the manufacturer or your nearest sales representative
to replace the board.
• Push ENTER Key.
• Set the parameters again.
Possible Solutions
Adjust b5-36 [PID HiHi Limit Level] and b5-37 [PID HiHi
Time].
Correct errors with the PID control wiring.
Examine the sensors on the control device side.
