Note 1. Depending on the parameter settings, various functions can be selected for multi-function in-
puts and multi-function contacts outputs.
Note 2. Functions in parentheses are default settings.
H Selecting Input Method
• Switches SW7 and SW8, both of which are located above the control circuit terminals, are used for
input method selection.
Remove the front cover and optional cover to use these switches.
