Troubleshooting 6-3
Possible Problems and Corrective Actions Table 6.B
Problem Corrective Action
The motor does not start — No output voltage to the motor. 1. Check the power circuit.
• Check the supply voltage.
• Check all fuses and disconnects.
2. Check the motor.
• Verify that the motor is connected properly.
3. Check the control input signals.
• Verify that the 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].
The drive is started but the motor is not rotating.
P01 - [Output Frequency] displays 0.0.
1. Check the motor.
• Verify that the motor is connected properly.
2. Check the frequency source P06 - [Frequency Command].
• Verify that a frequency signal is present at terminal block
TB3 — Either a -10 to +10V signal or a 4-20 mA signal.
• Verify that the Preset Frequencies are set properly.
3. Check the control input signals.
• Verify that SW1, SW2 and SW3 are correct. (Refer to the chart
in Chapter 5)
4. Check the following parameter settings.
• Verify that P59 - [Frequency Select] is showing the desired
frequency source.
• Verify that P58 - [Internal Frequency] is set to the desired
frequency.
5. Cycle power or use P56 - [Reset Functions] if you changed
P46 - [Input Mode].
The motor is not accelerating properly. 1. Check the motor.
• Verify that the motor is connected properly.
• Verify that no mechanical problems exist.
2. Check the following parameter settings.
• Verify that P30 - [Accel Time 1] or P69 - [Accel Time 2]
— whichever is currently used — is set properly.
• Verify that P43 - [Current Limit] is set properly.
• Verify that P38 - [Boost Volts] is set properly.
Drive will not operate in the run/forward or run reverse modes. 1. Verify that P46 - [Input Mode] is set to 1.
2. Verify that neither P73 - [Reverse Disable] nor P74 - [Analog
Select] is set to 1.
3. Verify that the power has been cycled for 1and 2 to take effect.
4. Verify that both the Run Forward and Run Reverse switches are
not closed simultaneously.
5. Cycle power or use P56 - [Reset Functions] if you changed
P46 - [Input Mode].
