Using Intelligent Input Terminals
Set Second Motor and Special-Set Second Motor
If you assign the [SET] or [S-ST] function to an intelligent input terminal, you can select
between two sets of motor parameters. The second parameters store an alternate set of
motor characteristics. Two type of inputs are available:
• Set Second Motor - The inverter can select a different motor only in Stop Mode.
• Special-Set Second Motor - The inverter can select a different motor in either Stop
Mode or Run Mode. The following parameter pairs can be alternately selected during
Run Mode: A020/A220, F002/F202, F003/F203, A042/A242, A043/A243, A061/
A261, A062/A262, A092/A292, A093/A293, A094/A294, A095/A295, A096/A296
When the terminal [SET] or [S-ST] is turned ON, the inverter will use the second set of
parameters to generate the frequency output to the motor. When changing the state of the
[SET] input terminal, the change will not take effect until the inverter is stopped.
When you turn ON the [SET] or [S-ST] input, the inverter operates per the second set of
parameters. When the terminal is turned OFF, the output function returns to the original
settings (first set of motor parameters). Refer to
Motors" on page 4–59

Notes:
•
If the terminal state for [SET] is changed while the
inverter is running, the inverter continues using the
current set of parameters until the inverter is
stopped.
•
You cannot configure the inverter to use [SET] and
[S-ST] terminals at the same time.

to motor. The selection of 1st or 2nd motor is
available only in Stop Mode.
