4 Types and functions of operations
4.1 Return-to-home operation
(common to the controller and driver modes)
This operation is performed to detect the home used in positioning operation. Return-to-home operation is
performed in one of three modes: sensor-less mode, 2-sensor mode and 3-sensor mode. Settings relating to
return-to-home operation are performed using the home parameters.
Note •
Performing the return-to-home operation in the absolute mode will write data to the
EEPROM. The EEPROM can be rewritten approx. 100,000 times.
•
When performing return-to-home operation with any
EZC
Ⅱ series or
EZA
series model,
do not change the return direction (from the motor side).
Sensor-less mode
This mode is available only when the controller is used in combination with an
EZS
Ⅱ
series,
EZC
Ⅱ
series
and
EZA
series actuator.
In the sensor-less mode, the table will move to the mechanical hard stop position.
Push-motion 1: Sensor-less return-to-home operation is performed at the starting speed of return (HVs).
Push-motion 2 (high speed): Sensor-less return-to-home operation is performed at the operating speed of
return (HVr).
