Figure 4-24 Setting the multi-speed function
In the preceding figure, DI7, DI4, DI8, and DI2 are used as the multi-frequency input
terminals, each of which has a bit value. The state combinations of these terminals
correspond to multiple frequencies, When (DI7, DI4, DI8, DI2) = (0, 0, 1, 0), the state
combination value is 2, corresponding to the value set in 12-02. The target running
frequency is automatically calculated by 12-02 x P0-10.
The SSI700 supports a maximum of four DI terminals to be used as the multi-frequency
input terminals. You can also use less than four DI terminals, and the empty bit is
considered to be 0.
4.6.8 Setting the Motor Rotating Direction
After the AC drive restores the default settings, press to drive the motor to rotate. In
this case, the rotating direction is regarded as the forward rotation. If the rotating direction
is reverse to the direction required by the equipment, power off the AC drive and
exchange any two of the output UVW cables (wait until the main capacitor of the AC drive
is completely discharged).
In some applications where both forward rotation and reverse rotation are required,
enable the reverse control (P8-13 = 0, default value) and meanwhile reverse the rotating
direction by setting P0-09 to 1. Then press to make the motor rotate in the reverse
direction, as shown in the following figure.
Figure 4-25 Reversing the motor rotating direction
If the command source is terminal control and reverse rotation is required, use the default
value 0 of P8-13 to enable reverse control.
