If you assign the [SET] or [SET3] functions to an intelligent input terminal, you can select 
between two or three sets of motor parameters. You may assign one or both of these functions. 
These second and third parameters store alternate sets of motor characteristics. When terminal 
[SET] or [SET3] is turned ON, the inverter will use the second or third set of parameters 
accordingly, generating the frequency output to the motor. When changing the state of the 
[SET] or [SET3] input terminal, the change will not take effect until the inverter is stopped.

When you turn ON the [SET] or [SET3] input, the inverter operates per the second or third set 
of parameters, respectively. When the terminal is turned OFF, the output function returns to the 
original settings (first set of motor parameters). Refer to 

 for details.

SET

Set 2nd Motor

ON

causes the inverter to use the 2nd set of 
motor parameters for generating the 
frequency output to motor

OFF

causes the inverter to default to the 1st 
(main) set of motor parameters for gener-
ating the frequency output to motor

17

SET3

Set 3rd Motor

ON

causes the inverter to use the 3rd set of 
motor parameters for generating the 
frequency output to motor

OFF

causes the inverter to default to the 1st 
(main) set of motor parameters for gener-
ating the frequency output to motor

C001, C002, C003, C004, 
C005, C006, C007, C008

(none)

Notes: 
• If the terminal state is changed while the 

inverter is running, the inverter continues 
using the current set of parameters until the 
inverter is stopped.

• If both SET and SET3 are ON at the same 

time, SET prevails and the 2nd motor param-
eters are in effect.
