* This parameter is made valid when the servo amplifier is powered OFF, then ON again after it has been transferred
from the AD75 to the servo amplifier.
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 " 0
H
" (initial value).
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 =
5600
4
= 1400 [pulse]
•
For dividing frequency ratio setting
Set " Pr.133 Option function 6" to " 1
H
".
The number of pulses per servomotor revolution is divided by the setting value.
Output pulses =
Resoution per servomotor revolution
Setting value
[pulse/rev]
(Example) When the setting is 8, the actually output A phase and B phase
pulses are as indicated below.
A phase and B phase output pulses=

= 4096 [pulse]
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.
0 : Invalid
F003
H
: Valid
