9.4 Pulse Output Function
Double pulse input driver (CW pulse input and CCW pulse input)
Since a double pulse input is used, switching must be performed by an external relay.
One output contact is used as a pulse output for relay switching.
The pulse output terminal and home input I/O allocation is determined by the channel
used. For detailed information
section 9.2.1
Set the control code for instruction F168 to “No directional output.”

* X2 or other desired input can be specified for the near home input.
** Y4 or other desired output can be specified for the relay switching. At this time, the relay
must be switched earlier by the amount of its operation time.
Caution when using a double pulse input driver
When using the FP0 pulse outputs Y0 and Y1 for direct connection to the CW input and
CCW input of a driver, the counter elapsed values for the separate channels (ch0 and
ch1) increase and decrease in response to the individual outputs. The elapsed values
can thus be sent to the program as necessary.
