Name
Set whether or not to invert the polarity of DI_5 signal used as DEC2 signal.
0: Do not invert
Deceleration LS
1: Invert
Inversion Selection
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).
Select the signal to be used as DEC2.
Deceleration LS Signal
0: Setting parameter OW05, bit 8
Selection
1: DI_5
Select the setting unit for OL10 (Speed Reference Setting), OL3E
(Approach Speed), and OL40 (Creep Rate.)
0: Reference unit/s
Speed Unit Selection
1: 10
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
Zero Point Return
parameter No.21 is 0.
Deceleration LS Signal
0: OFF
(DEC2)
1: ON
Speed Reference
Set the speed to use when starting a zero point return.
Setting
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 (OL10). Set the speed as a percentage of
Override
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
Zero Point Return
6: DEC2 + Phase-C Signal Method
Method
Set the approach speed.
Approach Speed
Only a positive value can be set; 0 or a negative value will result in an error.
Set the creep speed.
Creep Rate
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
Zero Point Return Travel
after passing the DEC2 signal.
Distance
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.
