(2) Number of virtual pulses per servo motor revolution
Parameter
Initial value Setting range Unit
No. Symbol Name
PA05 *FBP Number of virtual pulses per revolution 100 0, 100 to 500 × 100 pulse/rev
CAUTION
When this parameter is changed, turn off and on the power before starting the
operation. Otherwise, the set value will not be validated, causing an unexpected
operation.
POINT
This parameter is made valid when power is switched off, then on after
setting.
Set the number of virtual pulses necessary to rotate the servo motor one turn.
When parameter No. PA05 is set to "100 (10000[pulse/rev])" (initial value), the number of pulses necessary
to rotate the servo motor one turn is 10000 pulses. When parameter No. PA05 is set to "0", the number of
pulses necessary to rotate the servo motor one turn equals to the encoder resolution of the servo motor.
Parameter No. PA05 setting Description
0 Servo motor encoder resolution [pulse/rev]
100 to 500 Number of virtual pulses necessary to rotate the servo motor one turn [× 100 pulse/rev]
