Chapter Four Troubleshooting and Countermeasures
PV200 inverters supply many kinds of warning information and protection functions, when failure
occurred, function of protection actives, inverters will stop output, fault relay contact of inverter active,
and display the fault code on inverter operation panel. Before asking support, users can self-check
according to this chapter tips, and analyze the fault reasons, get the solutions. If fault still can’t be
solved, please ask for service, contact with agents or directly to ADA.

Troubleshooting
Err01
Acceleration
Overcurrent
1、Inverter output circuit
grounding or shorted
2、Acceleration time is too
short
3、Manually boost the torque or
V/F curve unsuitable
4、Voltage is too low
5、Start the rotating motor
6、Shock load on acceleration
7、Inverter selection is too
small
1、Peripheral
troubleshooting
2、Prolong the acceleration
time
3、Adjust the V/F curve
Or manually-torque-boost
4、The voltage adjusted to a
normal range
5、Select start on
rotational-speed tracking or
waiting for motor stopped
6、Cancel shock-load
7、Select inverter with a
larger power
Err02
Deceleration
Overcurrent
1、Inverter output circuit
grounding or shorted
2、Deceleration time is too
short
3、Voltage is too low
4、Shock load on deceleration
5、No installation of braking
resistor
1、Peripheral
troubleshooting
2、Prolong the deceleration
time
3、The voltage adjusted to a
normal range
4、Cancel shock-load
5、Install braking resistor
Err03
Constant-speed
Overcurrent
1、Inverter output circuit
grounding or shorted
2、Voltage is too low
3、If there is shock-load during
running
4、Inverter selection is too
1、Peripheral
troubleshooting
2、The voltage adjusted to a
normal range
3、Cancel shock-load
4、Select inverter with a
