(11)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.
Used to set the encoder pulses (A-phase, B-phas e) 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 di vision ratio setting.
The number of A/B-phase pulses actually outpu t is 1/4 times greater than the preset number of pulses.
The maximum output frequency is 4.6Mpps (after m ultiplication by 4). Use this parameter within this range.
(a) For output pulse designation
Set " 0" (initial value) in parameter No.PC19.
Set the number of pulses per servo motor revo lution.
Output pulse set value [pulses/rev]
For instance, set "5600" to Parameter No.PA15, the actually output A/B-phase pulses are as indicated
below.
45600A B-phase output pulses 1400[pulse] (b) For output division ratio setting Set " 1" in parameter No.PC19. The number of pulses per servo motor revoluti on is divided by the set value.
Output pulse [pulses/rev]
Resolution per servo motor revolution
Set value
For instance, set "8" to Parameter No.PA15, the actual ly output A/B-phase pulses are as indicated
below.
