[16] Creep sensor input polarity (Parameter No.20)
No. Name Symbol Unit Input Range
Default factory
setting
20 Creep sensor input polarity AIOF – 0 to 2
In accordance with
actuator
Even though the movement speed for most of the actuators at the home return is 20mm/s,
there are some actuators with other settings. Refer to the instruction manual of each actuator.
Even though the actuator with long stroke requires time to home-return if the power is shut at a
point far from the home position, the required time can be improved with using the creep
sensor.
The actuator moves at the creep speed (100mm/s or less) until a creep sensor signal is
detected, upon which the actuator will decelerate to the home return speed.
Creep sensor is an option for the line axis type.
This parameter is set properly prior to the shipment according to the specification of the
actuator.
Set Value Description
0 Not to use
1 Input is a contact
2 Input is b contact
