Operation Functions

The following five operation functions are provided.
• Homing
Homing is used to define the machine origin when the power supply is turned ON to equip-
ment that uses an incremental encoder.
Homing is not required for equipment that uses an absolute encoder because the positional
relationship between the origin of the absolute encoder and the machine origin is set in a
parameter.
• Positioning with a Program Table
You can register (program) positioning patterns in a table in advance and then use specifica-
tions from the host controller to specify the operation pattern to perform operation.
• Registration
If a trigger signal (/RGRT) is input from an external device during positioning, the motor will be
moved for the registration distance (RDST) that is registered in the program table.
• Constant Speed Operations with a Jog Speed Table
This function supports constant-speed operation at preset jog speeds.
• ZONE Outputs
This function outputs a zone number to indicate when the motor is within a preset zone. The
lower three programmable outputs are assigned.
