Input Terminals (On Right-hand Side)
No external power supply is required because a built-in power supply is provided.
Terminal
symbol
Name and description
Interface
SF
Forward/Stop
When the terminal is ON, the motor rotates in
the forward direction. When the terminal is OFF,
the motor stops.
SR
Reverse/Stop
When the terminal is ON, the motor reverses.
When the terminal is OFF, the motor stops.
24 VDC, 8 mA
S1
Multi-function input (see note 1)
(See note 3)
SC
Sequence input common
Input terminal common to SF, SR, and S1
FS
Frequency reference power supply
Output voltage: 12 VDC
Permissible amperage: 20 mA
FR
Frequency reference input (see note 2)
0 to 10 VDC is input.
Input impedance
FC
Frequency reference common
Input impedance
Note 1. Constant No. 06 (n06) is used to set this function. This constant is factory-set to
“fault reset.”
Note 2. FR can be switched to an amperage input terminal (4 to 20 mA) by setting the
internal DIP switch and constant No. 02 (operation mode selection). For details,
refer to 7-2 Frequency Reference by Amperage Input.
Note 3. The circuit for a 400-VAC-class Inverter is as shown below.
