Operation Mode Selection 1
Sn-04
(1) 1st digit
(frequency reference selection)
1st digit = 0: Reference input from control circuit terminal 13 or 14 is the master speed frequency
reference.
1st digit = 1: Frequency reference 1 (An-01) is the master speed frequency reference.
Note: For combination of multi-step speed operation, refer to pages 36 and 85.
(2) 2nd digit
(run command selection)
2nd digit = 0: Run command from control circuit terminal is accepted.
2nd digit = 1: Run command from the digital operator is accepted.
Valid run command and frequency references differ as shown in the table below, depending on the
combination of the 1st and 2nd digits.

Valid only when the inverter stops. (FWD run command, REV run command, and DC injection braking command are "open".)
É
FWD/REV run command is not accepted.
Ú
When the STOP key is depressed, processing differs as follows, depending on the setting of the 1st digit of Sn-05.
1st digit = 0:
During running by signals from control circuit terminals, the STOP key from the operator is accepted.
If the STOP key is depressed, the inverter stops according to the setting of 3rd and 4th digits of Sn-04, while the STOP LED indicator blinks.
This stop command is held within the inverter until both the FWD run command and REV run command of control circuit terminals become
"open", or another frequency reference is selected in the multi-step speed command or jog frequency reference section.
1st digit=1: During running by signals from control circuit terminals, the STOP key from the operator is not accepted.
