: Disabled ... Only frequency commands are governed by the preset-speed command (#1 to #15) entered.

: Enabled ... 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-command.

If you selected “enabled”,the motor runs operation mode setting directions as below

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.1) (+) + (+) = 

By entering , you can activate the reverse run function and the acceleration/deceleration time #2 function at the same time.

Ex.2) (+) + (+) + (+)= 

By entering , you can activate the forward run function and the acceleration/deceleration time #4 function at the same time.

(Selecting both of acc/dec switching #1 and acc/dec switching #2 means selection of acceleration/deceleration time #4. This manner is common to V/f pattern and torque limit.)
