7.10 Precautions for using the user units
(mechanical or composite system of units)
1. User units
Set the units for position and speed using operation parameter 1.
→
For details of operation parameter 1, refer to Subsection 11.1.1
1) System of units
Select the units to use.
The contents of setting are explained in "2) Set values for user units."
- Motor system of units :The position command and speed command are based on the number of
pulses.
- Mechanical system of units :The position command and speed command are based on mm, mdeg,
10
-4
inches and so on.
- Composite system of units :The position command is based the mechanical system, while the speed
command is based on the motor system, or similar composite units are used.
Note
When the system of units is set to "mechanical system of units" or "composite system of units", it is necessary
to set the pulse rate and feed rate.
2) Set values for user units
Set the units for position and speed as user units.
The following settings are offered by combinations of the system of units (b1 and b0) and unit setting (b3
and b2).
The unit for position is multiplied by "1", "10", "100" or "1000" in accordance with the setting of the position
data magnification setting.
→
For position data magnification, refer to "3) Position data magnification"
3) Data magnification
Selects the position data magnification ( 1, 10, 100 or 1000).
Note
The following position data is magnified by the position data magnification setting:
Example:
When target address 1 is "123" and the position data magnification is "x1000", the actual address (or travel
distance) is as follows in accordance with the system of units:
Motor system of units:
123 1000 =123000(PLS)
Mechanical system, Composite system of units: 123 1000 =123000( m, mdeg, 10
