Parameter Name Setting Contents
OW††3C Home Return Type 6: DEC2 + Phase-C Pulse Method
OL††10 Speed Reference
Sets the speed to use when starting a zero point return.
Only a positive value can be set.
An error will occur if a negative value is set.
OL††3E Approach Speed
Sets the approach speed shown in the preceding diagram.
Only a positive value can be set.
An error will occur if a negative value is set.
OL††40 Creep Speed
Sets the creep speed shown in the preceding diagram.
Only a positive value can be set.
An error will occur if a negative value is set.
OL††42 Home Offset
Sets the home offset distance shown in the preceding diagram.
If the sign is positive, travel will be in the same direction as the zero
point return direction.
if the sign is negative, travel will be in the direction opposite of the zero
point return direction.
Fixed parameter 21,
bit 0
Deceleration Limit Switch
Signal
It is possible to select the signal to use for DEC2.
0: Use setting parameter OW††05, bit 8.
1: Use the DI_5 signal.
Fixed parameter 1, bit
5
Deceleration Limit Switch
Inversion
It is possible to set whether or not to invert the polarity of the DI_5
signal, which is used for DEC2. (The status of OW††05, bit 8 cannot
be inverted.)
0: Do not invert.
1: Invert.
OW††05, bit 8
Deceleration Limit Switch
Signal for Zero Point
Return (DEC2)
When fixed parameter 21, bit 0 is set to 0, the DEC2 signal is input from
the ladder program.
0: OFF
1: ON
OW††03, bits 0 to 3 Speed Units
Sets the units for the Speed Reference (OL††10), Approach Speed
(OL††3E), and Creep Speed (OL††40).
0: Reference unit/s
1: 10
n reference unit/min.
2: 0.01%
3: 0.0001%
OL††18 Speed Override
This parameter allows the Zero Point Return speed to be changed
without changing the Speed Reference (OL††10). This setting can be
changed during operation.
This parameter has no effect on the Approach Speed (OL††3E) or
Creep Speed (OL††40).
Setting range: 0 to 32768 (0% to 327.67%)
Setting units: 1 = 0.01%
Example: Setting for 50% = 5000
