Chapter 5. Parameters
P15
Homing signal
Range
Contact A, contact B, Disable
[1],[0],[2]
Unit
RESET
Definition
Contact A: Set the input signal X0.4, X0.5 to NORMAL OPEN with the DOG switch. [1]
Contact B: Set the input signal X0.4, X0.5 to NORMAL CLOSE with the DOG switch. [0]
Disable: You can make this function null and invalid and can use the input signal
X0.4, X0.5 as an user signal. [2]
Description
This is a function to give a homing DOG signal function to the input signal X0.4, X0.5
Unless this function is given, you can use an user signal.
(Note) When using a homing DOG signal as a limit signal, set this value to the same
value set in the relevant limit signal. In this case, you can also use the
input signal X0.4, X0.5 as an user signal.
P16
Homing direction
Range
Minus, Plus
Unit
RESET
Definition
Minus: Homing return in the - direction [0]
Plus: Homing return in the + direction [1]
Description
Indicates the direction to which a homing DOG sensor is attached.
This function is valid when a parameter P15(homing signal) is set.
This function is reflected on the ‘ORG’ command when a PLC exclusive command is
used, and is reflected on the selection of a ‘manual feed axis direction selection
signal in the M80.C~ M80.F contact when a homing return of the contact M is executed.
P17
Homing method
Range
Method 1, method 2 [1],[2]
Unit
RESET
Definition
Method 1: Detect the homing DOG signal and then complete a homing return in the on-
going direction. [1]
Method 2: Detect the homing DOG signal and then complete a homing return in the
opposite direction.[2]
Description
Set a method for a homing return.
This function is valid when a parameter P15(homing signal) is set.
The homing methods differ depending on the types of MCU, whose description is as
follows:
When setting the method 1
MCU-XP2: Reduce the velocity after detecting a homing DOG signal, and then complete
the next homing return away from the homing DOG sensor in the on-going
direction.
MCU-XA2: Reduce the velocity after detecting a homing DOG signal, go away from the
homing DOG sensor, detect the C phase of the motor, and then complete the
homing return.
When setting the method 2
MCU-XP2: Reduce the velocity after detecting a homing DOG signal, and then complete
the next homing return away from the homing DOG sensor in the opposite
direction.
MCU-XA2: Reduce the velocity after detecting a homing DOG signal, go away from the
homing DOG sensor in the opposite direction, detect the C phase of the motor,
and then complete the homing return.
For details, refer to Chapter 3.
(Note) When replacing the homing DOG signal with a limit signal, set it using the
‘method 2’.
