Input terminals
• All COMs have the same electric potential.
• Change SW5 to external power source (EX) to connect
the power source between Input terminals 1 to 9, A or
B, and COM.
• Sink or source logic of the input terminal is switched by
SW6.

[RS:028]Reset
• Reset at every trip.
[SCHG:015]Command source change
• Change to the main speed command [AA101](OFF) or
sub-speed command[AA102](ON).
[JG:029]Jogging
• Run at a frequency of [AG-20] upon receipt of the operation
command by [JG]ON.
[FRS:032]Free-run stop
• [FRS]ON sets the motor in a free-run state.
[2CH:031]Two-step acceleration/deceleration
• [2CH]ON enables acceleration/deceleration
time-2[AC124][AC126].
[EXT:033]External trip
• [EXT]ON issues Trip[Er012].

parameter settings for each terminal.
terminal
Switching SW6 to SRC or SINK allows you to select SINK or
Source logic.
This is a terminal for pulse input. A and B terminals can be
Pulse input-A
used also as an input terminal.
Terminal functions are selectable according to the
parameter settings for each terminal.
Pulse input-B
The maximum input pulse rate is 32kpps.
This is a common terminal for digital input terminals

(1,2,3,4,5,6,7,8,9,A and B). Three COM terminals are
(common)
available.
