(Note 1) The setting (non-voltage/voltage, instantaneous unit time) of each channel should be performed
using the engineering tool. For the setting method, see
“
Chapter 7 Registering MCS
Configuration
”
of the
“
Engineering Tool Instruction Manual
”
(6F8C0696).
(Note 2) The pulse width must be at least
1 V for the pulse threshold set voltage.
