Wire Connection and Optional Devices
Input terminals
・
All COM terminals are at the same potential.
・
When connecting a power supply between 1-9, A,
B and COM, switch SW5 to the external power
supply (EX).
・
You can switch between the sink/source logic of
input terminals by using SW6.
(Wiring example)
・
[ ] indicates the factory default setting.
Initial terminal function
[RS] Reset
・
Resets when trip occurs.
[SCHG] Switch of frequency command
・
Switches between the main speed command
[AA111](OFF) and auxiliary speed command
[AA112](ON).
[JG] Jogging
・
When operation command is input with [JG]ON,
operation is performed at the frequency set for
[AG-22].
[FRS] Free-run stop
・
The motor performs free-run when [FRS] is ON.
[2CH] 2-stage acceleration/deceleration
・
When [2CH] is ON, the acceleration/deceleration
time 2[AC124]and [AC126] are enabled.
[EXT] External trip
・
When [EXT] is ON, trip [E012] is issued.
[FW] normal rotation and [RV] reverse rotation

Description
OFF OFF
The set frequency command is enabled
ON OFF
[Ab-11] frequency command is enabled
OFF ON
[Ab-12] frequency command is enabled
ON ON
[Ab-13] frequency command is enabled
*) By configuring CF3 and 4, you can configure up
to 15th speed.
[USP] Prevention of power restoration restarting
・
When [USP] is ON, upon power-on, trip [E013] is
issued if the operation command is issued.
