CLEAR Signal Output (DSZR/ZRN Instruction)

The DSZR instruction (zero return instruction with DOG search function) and ZRN instruction (zero return
instruction) can stop the workpiece at the origin, and can output the CLEAR signal.
If it is necessary to output the CLEAR signal after zero return, turn on the "CLEAR signal output function
enable" relay. The following table shows the "CLEAR signal output function enable" relay of each pulse
output destination device (Y000, Y001, Y002 and Y003).
Use an FX
device.
1. If it is not necessary to use the CLEAR signal device specification function, or if an FX
below Ver. 2.20 is used:
Pulse output

Y000
Y001
Y002
Y003
*1.
*2.
2. If it is necessary to use the CLEAR signal device specification function:
Turn on "CLEAR signal device specification function enable" relay to specify the CLEAR signal output device
(output Y) for the pulse output destination device using the CLEAR signal device specification register.
Pulse output

*3.
*4.
When using a high-speed output special adapter:
The output devices initially set for the CLEAR signal of the DSZR/ZRN instruction are the same output
devices as the "direction signal / reverse pulse train (rotation direction signals)" of the high-speed output
special adapters. Be sure to specify output numbers of other transistor outputs using the CLEAR signal
device specification function.
