No. 4
Command Unit
Setting Range Setting Unit Default Value
0 to 3 − 0
Set the units for the reference that is input.
The minimum reference unit is determined by this parameter and the Number of Decimal Places setting (fixed parameter 5). If
pulse is selected, the Electronic Gear Ratio (fixed parameters 8 and 9) will be disabled.
For details, refer to ( 1 ) Reference Unit under 4.5 Example of Setting Motion Parameters for the Machine.
0: pulse (electronic gear disabled)
1: mm
2: deg
3: inch
No. 5
Number of Decimal Places
Setting Range Setting Unit Default Value
0 to 5 − 3
Set the number of digits below the decimal point in the reference unit being input.
The minimum reference unit is determined by this parameter and the Command Unit (fixed parameter 4).
Example: When the Command Unit is set to mm and the Number of Decimal Places is set to 3, a reference unit of 1 will be 0.001
mm.
The setting of this parameter is disabled if the Command Unit is set to pulse in fixed parameter 4.
For details, refer to ( 1 ) Reference Unit under 4.5 Example of Setting Motion Parameters for the Machine.
No. 6
Command Units per Revolution (rotary motor) or
Linear Scale Pitch (linear motor)
Setting Range Setting Unit Default Value
1 to 2 31 −1 Reference unit 10000
When using a rotary motor, specify the amount of travel in the load as the number of reference units for each turn of the load
shaft. When using a linear motor, specify the linear scale pitch in reference units.
For details, refer to ( 1 ) Reference Unit under 4.5 Example of Setting Motion Parameters for the Machine.
No. 8
Gear Ratio [MOTOR]
Setting Range Setting Unit Default Value
1 to 65535 rev (revolutions) 1
These parameters determine the gear ratio between the motor and the load.
Set the following values for a configuration in which the load shaft turns n times in response to m turns of the motor shaft.
• Gear ratio at Servomotor: m
• Gear ratio at load: n
This parameter setting is disabled if the Reference Unit is set to pulse in fixed parameter 4 and a linear motor is selected.
For details, refer to ( 2 ) Electronic Gear under 4.5 Example of Setting Motion Parameters for the Machine.
