Chapter 5 Trial Operation and TuningASDA-A2R Series
5-4 Revision December, 2014
Warning of negative limit error:
Please check if any of the digital input DI1~DI8 is set to negative limit (NL) and that DI
is ON.
Corrective action:
If not desire to set negative limit (NL) as one of the digital input, make sure no
digital input is set to negative limit (NL) among DI1~DI8. (That is to say none of the
parameters, P2-10~P2-15 is set to 22.)
If the signal of negative limit (NL) is needed, make sure one of the digital input,
DI1~DI8, is set to negative limit (NL) and that DI has to be ON.
5) When the screen displays
Warning of positive limit error:
Please check if any of the digital input DI1~DI8 is set positive limit (PL) and that DI is
ON.
Corrective action:
If not desire to set positive limit (PL) as one of the digital input, make sure no
digital input is set to positive limit (PL) among DI1~DI8. (That is to say none of the
parameters, P2-10~P2-17 is set to 23.)
If the signal of positive limit (PL) is needed, make sure one of the digital input,
DI1~DI8, is set to positive limit (PL) and that DI has to be ON.
6) When the screen displays
Warning of overcurrent:
Corrective action:
Check the connection between the motor and servo drive.
Check if the conducting wire is short circuited.
Exclude short circuit and avoid metal conductors being exposed.
7) When the screen displays
Warning of under voltage:
Corrective action:
Check if the wiring of main circuit input voltage is correct.
Use voltmeter to measure if the main circuit voltage is normal.
Use voltmeter to measure if the power system complies with the specification.
Note: During the process of power on or servo on, if an alarm occurs or shows any
abnormal display, please contact the distributors.
