6.4.3 I/O Allocation
Double pulse input driver (CW pulse input and CCW pulse input method)
Two output contact are used as a pulse output for “CW, CCW”.
TheI/O allocation of pulseoutput terminal and home inputis determined by thechannel
used. (See the table of specifications on page 6 - 6.)
Set the control code for F171 (SPDH) instruction to “CW/CCW”.

Single pulse input driver (pulse input and directional switching input method)
One output point is used as a pulse output and the other output is used as a direction
output.
The I/O allocation of pulse output terminal, direction output terminal, and home input
is determined by the channel used. (See the table of specifications on page 6 - 6.)
Near home input is substituted by allocating the desired contact and turning on and off
the specified bit of special data register DT90052.
Up to two driver systems can be connected.
