alarm?
Condition: the time sequence is wrong when the absolute position is read by DI/O.
Cause:
Time sequence is wrong.
1.
Reading timeout.
2.
Correct the time sequence for reading the data with DI/O:
1.
DI.ABSQ switches to off after DO.ABSR is off.
(a)
DI.ABSQ switches to on after DO.ABSR is on.
(b)
Check the duration from when DO.ABSR switches on to the time when
2.
DI.ABSQ switches on and see if this duration is over 200 ms. The correct
procedure should be: when DO.ABSR switches on and after the bit data of
absolute position is ready, read DO.ABSD within 200 ms, switch DI.ABSQ on,
and then inform the servo drive that data reading is complete.
Cycle power on the servo drive.
Incremental motor does not support the absolute function.
Check whether your servo motor has an incremental or absolute encoder.
1.
Check the setting of P2.069 and correctly set the value. Set P2.069.X to 0 if
2.
desiring to operate the absolute motor as an incremental motor.
Set P2.069.X to 0 and then cycle power on the servo drive.
