Solutions
Contactor open 9 Er.Lv2
1: Instantaneous power failure occurs
on the input power supply
2: The frequency inverter's input
voltage is not within the allowable
range.
3: cut off the power during operation
4:the internal wiring of the inverter is
loose, or the hardware is bad.
1:Check if the input power
supply is abnormal, whether the
input power terminal is loose,
whether the input contactor or
the air switch is abnormal.
2:adjust the voltage to the
normal range
3:Power off after the inverter
stops
4:seeking technical support
5: For the unstable power
supply, if the performance
requirements are low, try to
enable the undervoltage stall
function (P23.00).
Frequency
inverter
overload
10 Er. oL
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 frequency converter selection is
too small
5:overload at low speed operation
1. Reduce the load and check
the motor and mechanical
conditions.
2, increase the acceleration
and deceleration time
3. Adjust the torque boost or
V/F curve
4, select the inverter with a
larger power level
5. Perform motor self-learning
in cold state and reduce carrier
frequency at low speed
Motor
overload
11 Er.oL1
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 related
parameters
Power input
phase loss
12 Er.iLP
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: Ask for technical support.
3: Ask for technical support.
4: Ask for technical support.
