15. Deceleration time
This setting specifies the time to decrease the pulse frequency.
Set the time between 10 and 10,000 ms in increments of 1 ms. The first digit of the setting is handled as zero. For example, if
144 is entered, the set value is handled as 140 ms.
16. Trigger to start monitoring origin input
Specifies the timing to start the origin signal monitor.
Timing
Proximity signal OFF→ON
Proximity signal ON→OFF
17. Reversible control enable
Selects the reversible control method from the following reversible control modes when ZRN mode 1 is selected for 9. Zero
return method. (This is an example when ZRN1 is used with the All-in-One CPU module.)
Reversible Control Enable
Reversible control disabled
Reversible control Single-pulse
output
Reversible control Dual-pulse
output
The outputs used on the FC6A Series MICROSmart vary based on the instruction used, the combination of the pulse output
mode and reversible control, and the model used.
Command
Reversible control disabled
ZRN1 Reversible control Single-pulse output mode
Reversible control Dual-pulse output mode
Reversible control disabled
ZRN2 Reversible control Single-pulse output mode
Reversible control Dual-pulse output mode
Reversible control disabled
ZRN3 Reversible control Single-pulse output mode
Reversible control Dual-pulse output mode
Reversible control disabled
ZRN4 Reversible control Single-pulse output mode
Reversible control Dual-pulse output mode
Note: The outputs (pulse output and reversible control output) used by ZRN instruction cannot be used by other instructions simultaneously.
18. Control direction
When reversible control is enabled, store 0 in this data register for forward operation and store 1 in this data register for reverse
operation.
18-42
After the proximity signal changes from off to on, the change from off to on in the origin signal is monitored.
After the proximity signal changes from off to on and then next changes from on to off, the change from off
to on in the origin signal is monitored.
Select this option when using pulse output in a single
direction. Pulse A and pulse B can be used independently.
Pulse A is used as pulse output. Pulse B on/off is used as
reversible control.
Pulse A is used as forward pulse (CW) output.Pulse B is
used as reverse pulse (CCW) output.
