2. Electronic gear function
The function multiplies the input pulse command from the host controller by the predetermined
dividing or multiplying factor and applies the result to the position control section as the positional
command. By using this function, desired motor rotations or movement distance per unit input
command pulse can be set.

4. Motor encoder pulse output
The information on the amount of movement can be sent to the host controller in the form of A and B
phase pulses from the servo driver.

5. Deviation Counter clear
The deviation counter clear input (CL) clears the counts of positional deviation counter at the position
control to 0.

Please refer to chapter 4
6. Position complete output (INP)
The completion of positioning can be verified by the positioning complete output (INP).When the
absolute value of the positional deviation counter at the position control is equal to or below the
positioning complete
Range by the parameter, the output is ON. Presence and absence of positional command can be
specified as one of judgment conditions.

Pr4.33
INP hold time
And the output port should be assigned for “INP”, for details of these parameters, refer to Pr4.10 –
Pr4.15.
7. Command pulse prohibit (INH)
The command pulse input counting process can be forcibly terminated by using the command pulse
inhibit input signal (INH).When INH input is ON ,the servo driver ignores the command
pulse ,disabling pulse counting function.
