Encoder Output Pulse - Mitsubishi Electric MELSERVO-J3 Series Instruction Manual

6. PARAMETERS

6.1.13 Encoder output pulse

No. Symbol
PA15 *ENR Encoder output pulse
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.
(1) For output pulse designation
Set " 0 " (initial value) in parameter No.PC19.
Set the number of pulses per servo motor revolution.
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.
A B-phase output pulses
(2) For output division ratio setting
Set " 1 " in parameter No.PC19.
The number of pulses per servo motor revolution is divided by the set value.
Resolution per servo motor revolution
Output pulse
For instance, set "8" to Parameter No.PA15, the actually output A/B-phase pulses are as indicated below.
