No. Data
1894 Feedback pulses from one revolution signal to one revolution signal
Data type : 2-word axis
Unit of data : Detection unit
Valid data range : 0 to 99999999
Set the position feedback pulses between the one revolution signals. The servo software
compares this parameter and the total pulses counter.
3. Alarm

the following alarm is generated.
No. 425
Message SERVO ALARM : n AXIS FEEDBACK ERR
Contents Incorrect position pulses are detected.
This alarm can not be cleared without power off / on.
4. Output Signal
