VFD500 high performance vector control frequency inverter user manual Chapter6 Fault diagnosis and solutions
1:The load is too large or the
motor is blocked.
2:The large inertia load
acceleration and deceleration
time is too short
3:When the VF is controlled, the
torque boost or V/F curve is not
suitable.
4:The motor selection is too
small
5:overload at low speed
operation
6:Improper setting of motor
parameters and motor protection
parameters
1. Reduce the load and
check the motor and
mechanical conditions.
Correctly set the motor
parameters and motor
protection parameters.
2, increase the
acceleration and
deceleration time
3. Adjust the torque boost
or V/F curve
4, select a motor with a
higher power level
5. Perform motor self-
learning in cold state and
reduce carrier frequency
at low speed
6, check the settings of
1: The three-phase power input
is
abnormal.
2: The drive board is faulty.
3: Thelightning proof board is
faulty.
4: The main control board is
faulty.
1:Eliminate external
faults.
2: A sk f o r t e c h nical
support.
3: A sk f o r t e c h nical
support.
4: A sk f o r t e c h nical
support.
1: The cable connecting the
frequency
inverter and the motor is faulty.
2: The frequency inverter's
t h r e e - p h a s e o u t p u t s a r e
unbalanced
when the motor is running.
3: The drive board is faulty.
4: The IGBT module is faulty.
1:Eliminate external
faults.
2: Check whether the
M o t o r t h r e e p h a s e
winding
is normal.
3: A sk f o r t e c h nical
support.
4: A sk f o r t e c h nical
support.
