Over voltage:
The main circuit voltage has exceeded its maximum allowable value or input power is error (Incorrect
power input).
Corrective Actions:
Use voltmeter to check whether the input voltage falls within the rated input voltage.
Use voltmeter to check whether the input voltage is within the specified limit.
2) When display shows:
Encoder error:
Check if the wiring is correct. Check if the encoder wiring of servo motor is loose or not.
Corrective Actions:
Check if the user performs wiring recommended in the user manual.
Examine the encoder connector
Inspect whether wire is loose or not.
Check if the encoder is damaged.
3) When display shows:
Emergency stop activated:
Please check if any of digital inputs DI1~DI8 signal is set to “Emergency Stop” (EMGS).
Corrective Actions:
If it is no need to use “Emergency Stop (EMGS)” as input signal, it only needs to confirm that if all
of the digital inputs DI1~DI8 are not set to “Emergency Stop (EMGS)”. (The setting value of
parameter P2-10 to P2-17 is not set to 21.)
If it is necessary to use “Emergency Stop (EMGS)” as input signal, it only needs to confirm that
which of digital inputs DI1~DI8 is set to “Emergency Stop (EMGS)” and check if the digital input
signal is ON (It should be ON).
