Can not modify the settings

The Clean Power VFD is in RUN mode.

Stop the Clean Power VFD to download the changed parameters from SmartD app on you smartphone.

The access parameters are incorrect.

Check your ID and password.

The motor does not run

The frequency setpoint is not set correctly.

Check the selection of the frequency setpoint.

The frequency selected setpoint is too low.

Check that the values of the selected frequency setpoint is above the minimum frequency.

The RUN/STOP I/O's are not wired accordingly to their preset functions.

Check the I/O's wiring and their preset functions.

Power is not supplied to R/L1 , S/L2 , T/L3

Check the terminal connections R/L1 , S/L2, T/L3 and U/T1, V/T2, W/T3.

Power supply is not correct

Check for decreased input voltage, input phase loss, and proper wiring.

Motor is not connected properly

Check the wiring between the Clean Power VFD and the motor.

Two-wire or three-wire type connection is wrong.

Check the connection.

The I/O's defined as RUN command is off.

Turn on the RUN I/O.

Both the forward and reverse rotation start signals are activated simultaneously.

Turn ON either forward or reverse rotation start signal

The motor is mechanically locked.

Unlock the motor or lower the load.

The emergency STO1 or STO2 is activated

Check the STO1 and STO2 wiring. Fix the Emergency signal that may have activate STO1 or STO2.Check the +24V on STO1 and STO2.

The source/Sink (PNP/NPN) selection is not consistent with the wiring of the I/O's.

Check the wiring mode selection setting.

The motor rotates in the opposite direction of the command.

The wiring for the motor output cable is incorrect.

Check if the cable on the output is wired with the correct sequence to the phase (U/V/W) of the motor.

The signal connection between the control circuit terminal (forward/reverse rotation) of the Clean Power VFD and the forward/reverse rotation signal on the control panel side is incorrect.

Check the forward/reverse rotation wiring.

The motor rotates in one direction only.

The single rotation direction has been selected in the Clean Power VFD settings.

Change to 2 directions rotation in the settings. Upload the new setting in the Clean Power VFD.

The reverse and/or forward input is not wired consistent with the I/O's setting.

Check the forward/reverse rotation wiring.

The motor is overheating

The load is too high.

Reduce the load.

Increase acceleration/deceleration time.

Check the motor parameters and set the correct values.

Replace the motor and the Clean Power VFD by models with appropriate capacity for the load.

The ambient temperature of the motor is too high.

Lower the environment temperature of the motor to operate within the motor manufacturer's specifications.

The motor fan has stopped or the fan is obstructed by foreign object.

Check the motor fan and remove any foreign object.

The motor does not accelerate or stops during acceleration

The load is too high.

Reduce the load.

Replace the motor and the Clean Power VFD by models with appropriate capacity for the load.

Increase the acceleration time.

The frequency setpoint is too low.

Set an appropriate value.

The acceleration time is too long.

Decrease the acceleration time.

Starting torque is too low.

Increase the starting boost torque value.

Motor speed varies during operation.

There is a high variance in load

Replace the motor and the Clean Power VFD by models with appropriate capacity for the load.

The input voltage varies.

Check your input power lines.

The motor vibrates and does not rotate normally.

The voltage between phases is not balanced.

Check the input and output voltage balance.

Check the motor's insulation.
