Name
Set whether or not to inverse the polarity of DI_5 signal used as DEC2 sig-
nal.
0: Do not invert
1: Invert
However, the deceleration limit signal for zero point return (OW05, bit
8) will not be invert even if this bit is set to 1 (invert).
Select the signal to be used as DEC2.
0: Setting parameter OW05, bit 8
1: DI_5
Select the setting unit for OL10 (Speed Reference Setting), OL3E
(Approach Speed), and OL40 (Creep Rate.)

reference units/min
2: Percentage of rated speed (1 = 0.01%)
3: Percentage of rated speed (1 = 0.0001%)
Used to input DEC2 signal from the ladder program when the bit 0 of fixed
parameter No.21 is 0.
0: OFF
1: ON
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.
This parameter allows the Zero Point Return speed to be changed without
changing the Speed Reference Setting (OL10). Set the speed as a per-
centage 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
4: DEC2 + ZERO Signal Method
Set the approach speed.
Only a positive value can be set; 0 or a negative value will result in an error.
Set the creep speed.
Only a positive value can be set; 0 or a negative value will result in an error.
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.
