Chapter 2 Installation and Wiring
2.11 Control circuit wiring section
■ 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.
(Wiring example)
• [] it means factory default settings.
■
Terminal’s default function ([symbol: setting No.])
[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].
[FW:001]Forward rotation and [RV:002]Reverse rotation
Forward Reverse Description
OFF OFF No command
ON OFF Forward rotation command operation
OFF ON Reverse rotation command operation
ON ON No command (inconsistent logic)
[CF1:003]Multispeed-1 and [CF2:004]Multispeed-2 commands

Description
OFF
OFF The set frequency source is enabled.
ON
OFF The frequency source of [Ab-11] is enabled.
OFF ON The frequency source of [Ab-12] is enabled.
ON ON The frequency source of [Ab-13] is enabled.
*) Setting CF3 and 4 allows you to set up to 16-speed.
[USP:034]Unattended start protection
• In a [USP]ON state, if an operation command has been input
before the power supply is ON, Trip[Er013] is issued.

Input
terminal
Terminal functions are selectable according to the
parameter settings for each terminal.
Switching SW6 to SRC or SINK allows you to select SINK or
Source logic.
Voltage between each input and
COM terminals
• ON voltage Min.DC18V
• OFF voltage Max.DC3V
• Max. allowable voltage DC27V
• Load current 5.6mA(at DC27V)

A Pulse input-A
This is a terminal for pulse input. A and B terminals can be
used also as an input terminal.
Terminal functions are selectable according to the
parameter settings for each terminal.
The maximum input pulse rate is 32kpps.
