You can select any of the ten operations to define home.
• Proximity reverse turn/home proximity input OFF
• Proximity reverse turn/home proximity input ON
• Home proximity input OFF
• Home proximity input ON
• Limit input OFF
• Proximity reverse turn/home input mask distance
• Limit inputs only
• Proximity reverse turn/holding time
• No home proximity input/holding home input
• Zero position preset
For details, refer to the NJ-series Motion Control Instructions Reference Manual (Cat. No. W508).
• You can set the stopping method when the limit input in the motion direction turns ON during homing.
• The stopping method depends on the limit input stop method.
• The limit input setting in the direction of motion is enabled. It is also enabled during motion at homing
velocity or homing approach velocity.
• If you set reversing in the limit input settings, an error stop will occur if the limit input signal in the
home input detection direction turns ON at homing approach velocity. However, this does not apply in
operation modes in which the home proximity signal is not used.
• An error will occur and operation will stop if you set reversing for the limit input operations in both
directions and the home input signal cannot be detected after moving from the limit input position
opposite to the home input detection direction to the other limit input position.
Homing Holding Time Set the holding time when you set the Homing Operation Mode to the
proximity reverse turn and holding time specification. (Unit: ms)
Homing Compensation Value Set the homing compensation value that is applied after the home is
defined. (Unit: command units)
Homing Compensation Velocity Set the velocity to use for homing compensation (command units/s).
