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).
