30 POSITIONING PARAMETER
30.2 Details of Parameters
■When set in m
In the positioning operation with transfer distance of 100 [m] and operation speed of 6 [cm/min], pulses are output as follows.
• Number of pulses to be generated = Transfer distance  Transfer distance per rotation  Number of pulses per rotation =
100 [m]  100 [m/REV]  4000 [pulse/REV] = 4000 [pulse]
• Pulse frequency = Operation speed

No. of Pulse per Rotation
Setting method: High Speed I/O Parameter
Set the number of pulses required to rotate a motor once, within 1 to 2147483647. This parameter must be set when the unit
setting is set to [Machine System] or [Multiple System]. When [Motor System] is set, the setting of this parameter is ignored.
Precautions
When the servo amplifier has an electronic gear setting, set this parameter considering the multiplication of the electronic
gear. The relation between the number of pulses per rotation and electronic gear is as follows.
• Number of pulses per rotation = Encoder resolution (positioning feedback pulse)  Electronic gear
For electronic gear, refer to the manual for each servo amplifier.
Movement Amount per Rotation
Setting method: High Speed I/O Parameter
Set the transfer distance of the machine per motor rotation within 1 to 2147483647. This parameter must be set when the unit
setting is set to [Machine System] or [Multiple System]. When [Motor System] is set, the setting of this parameter is ignored.
