4. Clearing position deviation
Set the function FunIN.35 for a DI to determine whether to clear the position deviation.
Function No.

Position deviation 
cleared
Valid: Clear
Invalid: Not clear
It is recommended that this 
function be allocated to DI8 
or DI9 and the logic of the 
corresponding terminal be set 
to edge valid. If you set the 
logic to level valid, the servo 
drive forcibly changes it to edge 
logic internally.
5. Frequency-division output
This parameter is used to select the pulse output source. The reference pulse synchronous 
output is used in the synchronous control scenario.

The servo drive performs frequency division on the pulses from the encoder based on the 
value of H05-17 and then outputs the processed pulses via the frequency-division output 
terminal. The value of H05-17 corresponds to the pulses from PAO/PBO at each revolution 
(before 4-frequency multiplication). In other words, the nal output pulses of PAO/PBO is four 
times of the setting value of H05-17.
