6.1.13 Encoder output pulse
Parameter
No. Symbol Name
Initial
Value
Unit Setting Range
PA15 *ENR Encoder output pulse 4000
pulse/
rev
1 to 65535
POINT
This parameter is made valid when power is switched off, then on after
setting, or when the controller reset has been performed.
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. PC19 to choose the output pulse setting or output division ratio setting.
The number of A/B-phase pulses actually output is 1/4 times greater than the preset number of pulses.
The maximum output frequency is 4.6Mpps (after multiplication by 4). Use this parameter within this range.
