Pr.138 Encoder output pulses
Set the encoder pulses (A phase, B phase) output by the servo amplifier. Set the
value 4 times smaller than the A phase and B phase pulses.
This parameter cannot be set on the peripheral device.
Set this parameter with a sequence program.
Use " Pr.133 Option function 6" to select the output pulses setting or output
dividing frequency ratio setting.
The number of A phase and B phase pulses actually output is 1/4 times greater
than the preset number of pulses.
The maximum output frequency is 1.3Mpulse (after multiplication by 4). Use this
parameter within this range.
•
For output pulses setting
Set " Pr.133 Option function 6" to "
Set the number of pulses per servomotor revolution.
Output pulses = setting value [pulse/rev]
(Example) When the setting is 5600, the actually output A phase and B phase
pulses are as indicated below.
A phase and B phase output pulses =
•
For dividing frequency ratio setting
Set " Pr.133 Option function 6" to " 1
The number of pulses per servomotor revolution is divided by the setting value.
Resoution per servomotor revolution
Output pulses =
(Example) When the setting is 8, the actually output A phase and B phase
pulses are as indicated below.

Pr.149 Servo parameter transmission setting
Set whether the encoder output pulse function and slight vibration suppression
function of the MR-J2S-B are valid or invalid.
This parameter cannot be set on the peripheral device.
Set this parameter with a sequence program.
