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.
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
