Two-step Infinitely Variable Speed Control (EP-2) (S4-1 = ON)

The TMU VFD features Two-step Infinitely Variable Speed Control and Decelerate to Stop using dynamic

braking.

y S1 input is RUN Forward. Frequency output increases to frequency set by DIP switch S2. Operation

continues at this frequency (minimum speed).

y S2 input is RUN Reverse. Frequency output increases to frequency set by DIP switch S2. Operation

continues at this frequency (minimum speed).

y AP input is acceleration. Frequency (speed) output increases. The longer this contact is closed, the

higher the speed output becomes. Limited only by the setting if DIP switch S2.

y During running S1 input and S2 input are Hold speed. Frequency output remains constant.

y Upon removal of S1 input and S2 input (RUN Forward/Reverse), the stopping method is Decelerate to

STOP. Output frequency decreases and the inverter decelerates to zero. Then the brake sets.

4.2.3 Motor Parameters

The motor parameters are selected by setting switches S4-2, S4-3 and S4-4. The motor parameters must

correspond to the motor type being used. The motor parameters are selected as follows:
