8.2 Motion Parameters
8-9
[ f ] Gear Ratio
[ g ] Infinite Axis Reset Position
[ h ] Encoder Settings
No. 8
Gear Ratio [MOTOR]
Setting Range Setting Unit Default Value
1 to 65535 rev (revolutions) 1
No. 9
Gear Ratio [LOAD]
Setting Range Setting Unit Default Value
1 to 65535 rev (revolutions) 1
Set the gear ratio between the motor and the load.
The following two values are set for a configuration in which the load shaft will turn n times in response to m turns of the motor
shaft.
• Gear ratio at Servomotor: m
• Gear ratio at load: n
The setting of this parameter is disabled if the Command Unit (Reference Unit) is set to pulse in fixed parameter 4.
No. 10
Maximum Value of Rotary Counter (POSMAX)
Setting Range Setting Unit Default Value
1 to 2 31 −1 Reference Unit 360000
Set the reset position when an infinite length axis is set.
Enabled when bit 0 of the Function Selection 1 (fixed parameter 1) is set to infinite axis.
No. 34
Rated Speed
Setting Range Setting Unit Default Value
1 to 32000 min -1 3000
Set the rated motor speed in 1 min −1 units.
No. 36
Encoder Resolution
Setting Range Setting Unit Default Value
1 to 2 31 −1 pulse 65536
Set the number of feedback pulses per motor rotation.
No. 42
Feedback Speed Moving Average Time Constant
Setting Range Setting Unit Default Value
0 to 32 ms 10
The Feedback Speed (monitoring parameter IL††40) is the value obtained by calculating the moving average for the time
constant from the feedback position for every scan.
