PA15 *ENR Encoder output pulses
This parameter is made valid when parameter No.PC03 is set to " 1 (initial
value)".
Set the encoder pulses (A/B-phase) output by the servo amplifier.
Set the encoder pulses output by the servo amplifier by division ratio.
Travel distance [pulse] of the linear encoder is divided by the set value.
Travel distance of linear encoder
Set value
Output pulse [pulse]
The number of A/B-phase pulses actually output is 1/4 times greater than the
preset number of pulses. Also, the maximum output frequency is 4.6Mpps (after
multiplication by 4). Use this parameter within the range.
