HV100 Series High Performance Current Vector Inverter

9.2 Exception handling
See table 9-2 for the common abnormal phenomena and countermeasures of inverter in operation:
Abnormal phenomena
Possible causes and countermeasures
The
motor
does
not
rotate
Keyboard does
not display
Check whether there is a power outage, whether the input power supply is out of
phase, and whether the input power cord is connected incorrectly
The keyboard is
not
displayed,
but the internal
charging
indicator is on
Check whether there are problems with the wiring and sockets related to the
keyboard, and measure the voltage of each control power supply in order to
confirm whether the switching power supply works normally. If the switching
power supply does not work normally, check whether the inlet (+,-) sockets of the
switching power supply are connected well, whether the starting vibration is
damaged or whether the voltage stabilizing tube is normal.
The motor is
buzzing
The motor load is too heavy, try to reduce the load
No
abnormalities
were found
Check whether it is in tripping state or not reset after tripping, whether it is in
power-off restart state, whether the keyboard has been reset, whether it has
entered program running state, multi-speed running state, specific running state
or non-running state, and try to restore the factory value.
Confirm whether the operation instruction is given
Check whether the operating frequency is set to 0
The motor cannot accelerate
and decelerate smoothly
Inappropriate setting of acceleration and deceleration time, increase acceleration
and deceleration time
If the current limiting value is set too small, increase the limiting value
Over-voltage protection acts during deceleration to increase deceleration time
Improper setting of carrier frequency, overload or oscillation
Overload and insufficient torque. Increase the torque boost value in V/F mode. If
it still cant meet the requirements, you can switch to automatic torque boost
mode. At this time, pay attention to the fact that the motor parameters should be
consistent with the actual values. If it still cant meet the requirements, it is
recommended to switch to advanced V/F control mode. At this time, you should
still pay attention to whether the motor parameters are consistent with the actual
values, and it is best to tune the motor parameters.
The motor power does not match the inverter power. Please set the motor
parameters to actual values
One with more than one motor. Please change the torque lifting mode to manual
lifting mode
Although the motor can
rotate, it can not adjust the
speed
Inappropriate setting of upper and lower frequency limits
The frequency setting is too low, or the frequency gain setting is too small
Check whether the speed regulation mode used is consistent with the set
frequency
Check whether the load is too heavy, over-voltage stall or over-current limit
The speed of the motor
changes during operation
Load fluctuates frequently, so minimize its variation
Inverter is seriously inconsistent with motor rating. Please set the motor
parameters to actual values
Poor contact of frequency setting potentiometer or fluctuation of frequency given
signal. Change to digital frequency giving mode or increase the filtering time
constant of analog input signal
The rotation direction of the
motor is opposite
Adjust the phase sequence of output terminals u, v and W.
Set the running direction (00.18=1) to reverse
Direction uncertainty caused by output phase failure, please check the motor
wiring immediately
