ASDA-A2
The digital inputs (DI6 ~ DI8) of the default value are the signals of negative limit error (NL),
positive limit error (PL), and emergency stop (EMGS), if not using the default setting of DI6 ~
DI8, adjusting the setting of P2-15 ~ P2-17 is a must. Parameters could be set to 0 (disable this
DI function) or modified to another function.
From the last setting, the servo drive status displays parameter P0-02 setting as the motor
speed (07), then the screen display will be:
When the screen displays no text, please check if the power of control circuit is under voltage.
1) When the screen displays:
Warning of overvoltage:
It means the voltage input by the main circuit is higher than the rated voltage or power
input error (incorrect power system).
Corrective action:
 Use the voltmeter to measure if the input voltage from the main circuit is within the
range of rated voltage value.
 Use the voltmeter to measure if the power system complies with the specification.
2) When the screen displays:
Warning of encoder error:
Check if the motor encoder is securely connected or the wiring is correct.
Corrective action:
 Check if the wiring is the same as the instruction of the user manual.
 Check the encoder connector.
 Check if the wiring is loose.
 Check if the encoder is damaged.
