• Motor Does Not Start

(No output voltage to motor)

1. Check power circuit.

- Check supply voltage.
- Check all fuses and disconnects.

2. Check the motor –

Verify that it is connected properly.

3. Check control input signals.

- Verify that START signal is present.
- Verify that the contact closure signal is present at TB3-8.
- Verify that either the RUN FORWARD or RUN REVERSE signal

is active, but NOT both.

4. Check P46 - [Input Mode].

- If P46 - [Input Mode] is set to 2, only the program keypad

module Start button will start the motor.

5. Cycle power or use P56 - [Reset Functions] if you changed

P46 - [Input Mode].

• Drive Started but Motor NOT Rotating

(P01 - [Output Frequency] displays “0.0”)

1. Check the motor –

Verify that it is connected properly.

2. Check frequency source P06 - [Frequency Command].

- Verify that a frequency signal is present at terminal block

TB3. Either a –10 to +10V or 4-20 mA signal.

- Verify that Preset Frequencies are set properly.

3. Check control input signals.

- Verify that SW1, SW2 and SW3 are correct. (Refer to the

chart in the User Manual at the end of Chapter 5).

4. Check parameter settings.

- Verify that P59 - [Frequency Select] is showing the desired

frequency source.

- Verify that P58 - [Internal Frequency] is the desired value.

5. Cycle power or use P56 - [Reset Functions] if you changed

P46 - [Input Mode].

• Motor Not Accelerating Properly

1. Check the motor –

Verify that it is connected properly and that

no mechanical problems exist.

2. Check parameter settings.

- Verify that P30 - [Accel Time 1] or P69 - [Accel Time 2]

(whichever is current used) is set properly.

- Verify that P43 - [Current Limit] is set properly.
- Verify that P38 - [Boost Select] is set properly.

• Can Not Operate in “RUN FWD/RUN REV” Mode

1. Verify that P46 - [Input Mode] is set to 1.

2.

Verify that the contact closure signal is present at TB3-8

.

3. Verify that P73 - [Reverse Disable] and P74 - [Analog

Select] are not set to 1.

4. Verify that power has been cycled for above change to take

effect.

5. Verify that both RUN FORWARD and RUN REVERSE switches

are NOT closed simultaneously.

6. Cycle power or use P56 - [Reset Functions] if you changed

P46 - [Input Mode].
