10.4.3 I/O Allocation
Double pulse input driver
(CW pulse input and CCW pulse input method)
• Two output contacts are used as a pulse output for “CW, CCW”.
• The I/O allocation of pulse output terminal and home input is determined by the channel used.
• Set the control code for F171 (SPDH) instruction to “CW/CCW”.
* Input such as X100 or X101 on the pulse I/O
cassette can be specified for the near home
* Input such as X200 or X201 on the pulse I/O
cassette can be specified for the near home
Note) If there is no input remained on the pulse I/O cassette, the input of the main unit can be used.
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.
• Near home input is substituted by allocating the desired contact and turning on and off the <bit4> of
special data register DT90052.
• Up to two driver systems can be connected.
* Input such as X100 or X101 on the pulse I/O
cassette can be specified for the near home
input.
* Input such as X200 or X201 on the pulse I/O
cassette can be specified for the near home
input.
