5 Motion Control Parameters
5-8
NJ-series CPU Unit Motion Control User’s Manual (W507)
•
The value set on the Servo Drive’s node address switches is loaded only once when the Servo
Drive’s control power is turned ON. Such changes are enabled only after the power supply is
turned ON again. Do not change the setting on the node address switches after the power
supply has been turned ON.
•
An error occurs if the same node address is used more than once.
•
The value set from the Sysmac Studio will be used for all non-OMRON slaves, regardless of
any setting at the slave.
These parameters set position units.
*1
This is the numerator of the electronic gear ratio (unit conversion formula).
*2
For example, if the encoder resolution is 10,000 pulses/rotation, set 10,000.
*3
This is the denominator of the electronic gear ratio (unit conversion formula).
Positions are generally given in pulses between the MC Function Module and Servo Drives or
encoder input terminals. Use a display unit of millimeters or degrees for motion control instructions
so that you can easily understand the operation.
You can use the Unit of Display parameter and electronic gear (unit conversion formula) settings to
change from a pulse unit to millimeters or degrees.
You can use the Unit of Display parameter to set the unit to display on the Sysmac Studio. The display
shows the position's display unit. The following table describes the units you can set.
