8 - Troubleshooting & Maintenance

Condition

Check Point

The motor
does
not rotate

1) Main circuit inspection

•

Is the input(line) voltage normal.(If the LED in the drive is lit)

•

Is the motor connected correctly?

2) Input signal inspection

•

Do the operating signal input to the drive.

•

Do the forward and the reverse signal input simultaneously to the drive?

•

Do the command frequency signal input to the drive.

3) Parameter setting inspection

•

Is the reverse prevention (FU1-03) function set?

•

Is the operation mode (FU1-01) set correctly?

•

Is the command frequency set to 0?

4) Load inspection

•

Is the load too large, or is the motor restrained.(mechanical brake)

5) Other

•

Is the alarm displayed on the keypad, or the alarm LED (STOP LED blinks)
lit.

The motor
rotates at
opposite
directions

•

Is the phase sequence of the output terminal U,V,W correct.

•

Is the starting signal (forward/reverse) connected correctly?

The
difference
between the
rotating speed
and the
reference is
too big

•

Is the frequency reference signal correct.(Check the level of the input
signal)

•

Is the following parameter setting is correct.

•

Lower Limit Frequency(FU1-24), Upper Limit Frequency(FU1-25), Analog
Frequency Gain(I/O-1~10)

•

Is the input signal line is influenced by external noise.(Use a shielded wire)

The drive
does not
accelerate or
decelerate
smoothly

•

Is the acceleration/deceleration time is set too short.

•

Is the load too large?

•

Is the Torque Boost (FU1-27, 28) value is too high that the current limit
function and the stall prevention function do not operate.

The motor
current is too
high

•

Is the load too large?

•

Is the Torque Boost Value (manual) too high?

The rotating
speed does
not increase

•

Is the Upper Limit Frequency (FU1-25) value is correct.

•

Is the load too large?

•

Is the Torque Boost (FU1-27, 28) value is too high that the stall prevention
function (FU1-59, 60) does not operate.

The rotating
speed
oscillates
when the
drive is
operating.

1) Load inspection

•

Is the load oscillating?

2) Input signal inspection

•

Is the frequency reference signal oscillating?

3) Other

•

Is the wiring too long when the drive is using V/F control.(over 500m)
