4. PARAMETERS
4.1.13 Encoder output pulses
No. Symbol
PA15 *ENR Encoder output pulses
PA16 *ENR2 Encoder output pulse electronic gear
Used to set the encoder pulses (A-phase, B-phase) output by the servo amplifier.
Set the value 4 times greater than the A-phase or B-phase pulses.
You can use parameter No. PC13 to choose the output pulse setting or output division ratio setting.
The number of A/B-phase pulses actually output is 1/4 of the preset number of pulses.
The maximum output frequency is 4.6Mpps (after multiplied by 4). Use this parameter within this range.
(1) For output pulse designation
Set parameter No. PC13 to "
Set the number of pulses per servo motor revolution.
Output pulse = set value [pulses/rev]
For instance, when parameter No. PA15 is set to "5600", the A/B-phase pulses actually output are as
indicated below.
