Example of 7-step speed operation

4)Setting the operation mode

An operation mode can be selected for each preset speed.

￿: Preset speed operation with no mode ········ Only frequency commands are governed by the preset speed command (1 to 15) entered.

￿: Preset speed operation with mode ··············· The direction of rotation, the V/f control mode, the acceleration and deceleration times and the torque limit can be set individually for each preset speed command.

!If you selected “enabled” (￿￿￿￿=￿), the motor runs operation mode setting directions as below without following terminal F, R.

!For the settings marked with +, more than one function can be selected at the same time by entering the sum of the numbers of the desired functions.

Ex.) (+￿) + (+￿) = ￿

By entering “￿”, you can activate the reverse run function and the acceleration/deceleration switching signal 1 function at the same time.
