Table 5.1: Solution for the most frequent problems
1. Check all power and control connections
1. Check if the parameter values are correct for the
application
1. Check whether the inverter is disabled due to a fault
condition
1. Decrease the motor overload
2. Increase P136, P137 (V/f)
1. Stop the inverter, turn off the power supply, check and
tighten all the power connections
2. Check all the internal connections of the inverter
1. Identify the cause of the oscillation. If the cause is electrical
noise, use shielded cables or separate them from the
power or command wiring
2. Interconnect the GND of the analog reference to the
grounding connection of the inverter
1. Check whether the values of P133 (minimum speed) and
P134 (maximum speed) are properly set for the used
motor and application
1. Check whether the used motor matches the application
1. Rated values must be within the limits specified below:
200 / 240 V power supply: Min: 170 V - Max: 264 V
110 / 127 V power supply: Min: 93 V - Max: 140 V
1. Replace the fuses
