7.2 Motion Command Details
7.2.3 Zero Point Return (ZRET)
7-36
Related Parameters
Parameter Name Setting
Fixed Parameter
No. 1, Bit 5
Deceleration LS
Inversion Selection
Set whether or not to invert the polarity of DI_5 signal used as DEC2 signal.
0: Do not invert
1: Invert
However, the deceleration limit signal for zero point return (OW
05, bit
8) will not be inverted even if this bit is set to 1 (invert).
Fixed Parameter
No. 21, Bit 0
Deceleration LS Signal
Selection
Select the signal to be used as DEC2.
0: Setting parameter OW
05, bit 8
1: DI_5
OW 03,
Bits 0 to 3
Speed Unit Selection
Select the setting unit for OL 10 (Speed Reference Setting), OL 3E
(Approach Speed), and OL 40 (Creep Rate.)
0: Reference unit/s
1: 10
n reference units/min
2: Percentage of rated speed (1 = 0.01%)
3: Percentage of rated speed (1 = 0.0001%)
OW 05, Bit 8
Zero Point Return
Deceleration LS Signal
(DEC2)
Used to input DEC2 signal from the ladder program when the bit 0 of fixed
parameter No.21 is 0.
0: OFF
1: ON
OL 10
Speed Reference
Setting Set the speed to use when starting a zero point return.
Only a positive value can be set; a negative value will result in an error.
OW 18 Override
This parameter allows the Zero Point Return speed to be changed without
changing the Speed Reference (OL
10). Set the speed as a percentage of
the Speed Reference Setting. This setting can be changed during operation.
Setting range: 0 to 32767 (0% to 327.67%)
Setting unit: 1 = 0.01% (Example) Setting for 50%: 5000
OW 3C
Zero Point Return
Method
6: DEC2 + Phase-C Signal Method
OL 3E Approach Speed
Set the approach speed.
Only a positive value can be set; 0 or a negative value will result in an error.
OL 40 Creep Rate
Set the creep speed.
Only a positive value can be set; 0 or a negative value will result in an error.
OL 42
Zero Point Return Travel
Distance
Set the travel distance from the point where the ZERO signal is detected
after passing the DEC2 signal.
If the sign is positive, travel will be toward the zero point return direction; if
the sign is negative, travel will be away from the zero point return direction.
