Hitachi SJ300 Series Third Motors, Set Second or

4–18

Using Intelligent Input Terminals

Set Second orThird Motors

Operations and Monitoring

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 “Configuring the Inverter for Multiple Motors” on page 4–72 for details.

• If both SET and SET3 are ON at the same time, SET prevails and the 2nd motor parameters are in effect.
