Parameter Details
Set the external encoder phase-Z regeneration width with time.
You can output the phase-Z signal at least for the period of time that has been set if the phase-Z
signal width is too short for detection due to the travel distance from the external encoder.
Select the regeneration method of pulse outputs A and B when a 90
° phase difference output type
external encoder is used.
Explanation of Set Values
*1. Through outputs are always made for phase Z without signal regeneration.
*2.
If the signal regeneration setting is selected, the duties of A and B are regenerated on the amplifier side
and disturbance of waveforms can be suppressed. Take note, however, that this causes delays in phase Z.
Set the compensation gain for the disturbance torque.
Set the filter time constant for disturbance torque compensation.
After the cause of a warning is cleared, the warning state is held for the number of seconds set
with Warning Latch Hold Time Selection (Pn627).
When 0 is set, the warning state is held even after the cause of the warning is cleared.

The warning state is held even after the cause of the warning is cleared.
To clear the warning state, execute the alarm clear.
1 to 10
The warning state is held for the set number of seconds after the cause of the warning is
cleared.
For example, when 3 is set, the warning state is held for 3 seconds after the cause of the
warning is cleared.
