No external power supply is required because a built-in power supply is provided.
Terminal
symbol
Name and description Interface
SF Forward/Stop (see note 3)
The motor will rotate in the forward direction when the
signal on this terminal is turned ON. The motor will stop
rotating when the signal is turned OFF.
S1 to S3
24 V
3.3 K
SR Reverse/Stop (see note 3)
The motor will rotate in the reversed direction when the
signal on this terminal is turned ON. The motor will stop
rotating when the signal is turned OFF.

Note 1. Functions are set with constants n06 to n08. Only n06: S1 is, however, available to the stan-
dard model.
Refer to the following for factory settings:
S1: Fault reset (n06=1)
S2: External fault (input to contact a) (n07=2)
S3: Multi-step speed command (n08=4)
Note 2. The FR terminal will function as a 4- to 20-mA input terminal with the setting of the internal
switch 1 (SW1) and n02 for operation mode selection.
Note 3. The sequential input method will change with the setting of the internal switch 2 (SW2).

Note Constant No. 09 (n09) is used to set the function. This constant is factory set to “during running.”
