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].

Fault Codes
Fault
No. Fault Indication and Corrective Action
03 Power Loss Fault
Monitor incoming AC line for low voltage or line power
interruption.
04 ➊ UnderVoltage Fault
Monitor incoming AC line for low voltage or line power
interruption.
05 ➊ OverVoltage Fault
Bus overvoltage caused by motor regeneration. Monitor
incoming AC line for excessive voltage. Extend the decel
time or install dynamic brake module or external capacitor module.
06 ➊ Motor Stall Fault
Longer acceleration time or a reduced load required.
07 ➊ Motor Overload Fault
Reduce motor load until drive output current does not
exceed the current set by P42 - [Motor Overload
Current]. Reduce P38 - [Boost Select].
08 ➊ Over Temperature Fault
Clear blocked or dirty heat sink fins. Check ambient temperature. Check for blocked or non-operating fan.
11 Operator Error
Clear fault. Do not remove keypad under power.
12 ➊ Overcurrent FauIt
Check short circuit at the drive output or excessive load
conditions at the motor.
13 ➊ Software Overcurrent Fault
A longer acceleration time, reduced load, or removal of
motor shaft blockage is required.
