L2002 Inverter

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 “Configuring the Inverter for Multiple Motors” on page 4–58 for details.

•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.
