Diagnose & Remedy
Check connection to analogue input
Disable input for fault trigger
1. Run self test routines
2. Change inverter
1. Change value of P2268
2. Adjust feedback gain
1. Change value of P2267
2. Adjust feedback gain
1. Inverter may run but certain actions will not
function correctly
2. Replace inverter
Check the following:
1. No breakage, seizure or obstruction of drive
train.
2. Proper operation of external speed sensor, if
in use.
3. P0402 (pulse per min at rated speed), P2164
(hysteresis freq. deviation) and P2165 (delay
time for permitted deviation) must have
correct values.
4. P2155 (threshold frequency f1), P2157
(threshold frequency f2), P2159 (threshold
frequency f3), P2174 (upper torque threshold
1), P2175 (lower torque threshold 1), P2176
(delay T_Torque), P2182 (upper torque
threshold 2), P2183 (lower torque threshold
2), P2184 (upper torque threshold 3) and
P2185 (lower torque threshold 3) must have
correct values.
