7.9. Motor troubleshooting
In the following pages, explanations will be provided on the possible causes of each
alarm and malfunction, the investigative methods and taking corrective measures.
7.9.1. Taking Measures at the time of Alarm Occurrence
When an alarm occurs, the 7-segment LED displays an alarm code with blinking. Besides,
it is possible to output the three upper bits (bits 7,6,5) of an alarm code as a general
purpose external output.
When an alarm occurs, in order to resume operation, confirm the contents in 7.9.1.1
Alarm List, rectify the cause first according to the correct measures (7.9.1.2), and ensure
the safety.
7.9.1.1. The List of Alarm and Warning
Indicate alarm and warning. The alarm can be cleared by inputting Alarm Reset (RST).
The alarm “No” in Alarm Clear can not be cleared unless the control power supply is shut
off. The operation at the time of detection “DB” means dynamic brake and “SB” means
deceleration to stop at sequence current limit value. (“-“ is an alarm detected only in
initial processing.) Note that when select dynamic braking as a forced stop function, the
operation at the time of detection certainly becomes dynamic braking.
