Panasonic A4P Series Home Sensor + Z Phase based on the front end, Positive direction Home sensor

Homing Operation

Home Sensor + Z Phase (based on the front end)

Example: Z phase count = 3 at an operation in a positive direction

		Direction of homing

(1) A starting point is between the ￿		L-SPD	H-SPD
home sensor and negative ￿
direction limit sensor (also on ￿
the negative direction limit sensor)
(2) A starting point is on ￿		L-SPD

	H-SPD	H-SPD
(3) A starting point is between the ￿		L-SPD

and home sensor		H-SPD
(4) A starting point is on the ￿		L-SPD

		H-SPD

Detect the home sensor (at the front end) in a direction of homing by 16.Pr30 (Homing speed (high)), get out of the home sensor area once and detect the home sensor (at the front end) by 16.Pr31 (Homing speed (low)) again. After that, count the Z phase specified times by 16.Pr3B (Homing Z-phase count setting) and define that point as a home position.

• Parameters related to this operation

Parameter number		Description￿
￿	30￿	Specify the high speed for the homing operation (0 to 6000 r/min).￿
￿
	31￿	Specify the low speed for the homing operation (0 to 6000 r/min).￿
￿	32￿	Specify the offset operation speed if the home offset operation is performed (0 to 6000 r/min). For the home
￿	￿	offset operation, refer to page 124.￿
￿	33￿	Specify the acceleration for the homing operation in a range between 0 to 3000 r/min.￿
16.Pr**￿	34￿	Specify the deceleration for the homing operation in a range between 3000 to 0 r/min.￿
￿
	35￿	Specify an operating direction for the homing. (0: positive direction, 1: negative direction)￿
￿
	36￿	Specify a type of homing. ([0]: Home sensor + Z phase (based on the front end))￿
￿	37￿	Specify whether or not to perform the home offset operation. (0: Not perform, 1: Perform) For the home offset
￿	￿	operation, refer to page 124.￿
￿	3B￿	Specify the Z phase that an operation stops. ([3] (the 3rd Z phase) in this example)￿
32.Pr**	01	Specify the home offset (–2147483647 to 2147483647 pulses). ￿
		If the home offset is not required, specify “0”.

Caution

1)If any of the set values of the parameters below is “0”, an operation trips due to homing error protection (error code No. 68) and stops according to an operation at alarm occurrence.
