Chapter 5 Trial Run and Tuning Procedure
1) When display shows:
Overvoltage:
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 main circuit 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 (CN2) of servo motor is loose
or incorrect.
Corrective Actions:
Check if the users perform wiring recommended in the user manual.

Examine the encoder connector and cable.

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 does not need to use "Emergency Stop (EMGS)" as input signal, the users only

need 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.)
