(Example) Rotate the motor by 60 degrees with an overall reduction ratio of 18/365
* You can set any value by setting any value for the numerator and denominator. However, the motor action will not
follow the extreme setting of the ratio. It is recommended to set within a range from 1/50 to 20.
Relationship between motor speed
and input pulse frequency
Pulley ratio: 18/60
Gear ratio: 12/73
Overall reduction: 18/365
Set the parameter so that motor
turns 60Åãwith 10000 pulses when
a command is entered from the
controller to the amplifier.
<Notes>
Default: The motor output shaft turns one revolution with 10000 pulses.
