ZRN (Zero Return)
ZRN Mode 0
The zero return is performed by monitoring only the proximity signal specified by S3.
ZRN Mode 1
The zero return is performed by monitoring the proximity signal (decrease frequency trigger) specified by S3 and the origin
signal (stop trigger) specified by S4.
After stopping pulse output with the origin signal, the complete signal specified by D2 can be output.
For ZRN mode 1, the timing to start monitoring the origin signal can be selected from the following two types.
Start monitoring the origin signal with the rise in the proximity signal
The ZRN instruction outputs pulses while monitoring multiple
signals to perform a zero return.
When the input is on, pulses are output according to the frequency
change settings stored in the control register specified by S1.
The pulse control information (output on/output complete/error) is
stored in the internal relays specified by D2 as the operation status.
When the initialization input specified by S2 is turned on, the
initial values configured in the WindLDR
ZRN (Zero Return)
dialog box are stored in the control registers.
The zero return method an be selected a
ZRN mode 0
or
ZRN
mode 1
.

(1) When a rise in the proximity signal is detected, the frequency
changes from the initial pulse frequency to the creep pulse
frequency.
(2) When a fall in the proximity signal is detected, pulse output stops.
(1) The rise in the proximity signal is detected, the frequency starts
being decreased, and at the same time the origin signal starts
being monitored.
(2) The rise in the origin signal is detected and pulse output is stopped.
(3) When pulse output stops, the complete signal turns on at the
same time.
(4) The on period for the complete signal is one scan or longer but
less than two scans.
