5.5 Fault Detection
5.5 Fault Detection
When the drive detects a fault, the digital operator displays the fault information,
the fault contact closes, and the motor coasts to a stop. However, a fault that has a
selectable stopping method will operate according to that stopping method.
Investigate the cause of a fault and refer to Table 5.9 for the appropriate action.
To restart, reset the fault with one of the following procedures:
• Set “14: Fault Reset” to a multi-function digital input (H1-01 to H1-06). Then,
close and open the input.
• Press the RESET button of the digital operator.
• Shut off the drive input power and then turn on again.

Option Communication Error
• After establishing initial communication, the connection was lost.
• Only detected when the run command frequency reference is assigned to an
option card.
Cause Possible Solution
No signal is being received from the
PLC.
• Check for faulty wiring.
• Correct the wiring.
• Check for loose wiring and short circuits. Repair as needed.
The communication cable is faulty
or a short circuit exists.
A communications data error
occurred due to noise.
• Check the various options available to minimize the effects of noise.
• Take steps to counteract noise in the control circuit wiring, main circuit lines
and ground wiring.
• Ensure that other equipment such as switches or relays do not cause noise and
use surge suppressors if required.
• Use cables recommended by Yaskawa or another type of shielded line.
Ground the shield on the controller side or on the drive input power side.
• Separate all wiring for communications devices from drive input power lines.
Install a noise filter to the input side of the drive input power.
The option card is damaged.
• Replace the option card if there are no problems with the wiring and the error
continues to occur.
The option card is not properly
connected to the drive.
• The connector pins on the option card are not properly lined up with the
connector pins on the drive.
• Reinstall the option card.
