How to Control the Frequency Converter
Either AV:1 or AV:2 controls the drive reference. Only one of them can control the frequency converter at a time and BV:2 decides which one.
1
This value is not directly available in the frequency converter. The value must be calculated as follows: AV#3=(Par. 16 -17)/(Par. 4 -13) x 100%
2
This value is not directly available in the frequency converter. The value must be calculated as follows: AV#4=(Par. 16 -52)/(Par. 20 -14) x 100%

17, 34 Loss of communication with the network.
13, 40, 41, 42, 59 Instantaneous output current has exceeded inverter rated or pro-
grammed value.
11, 29, 65, 69, 74, Heat sink temperature limit has been reached.
244, 245, 247
49, 62 Inverter has exceeded maximum or programmed limit.
5, 7, 64 DC bus voltage has exceeded inverter limit.
1, 6, 8 DC bus voltage is lower than required inverter limit.
16 Inverter output has shorted phase to phase.
14 Inverter output grounding current has exceeded manufacturer limit.
10, 50-58, 222 Motor is overloaded.
9 Timed over current fault.
12 Programmed limit for torque has been exceeded.
142 External fault has been activated in the inverter. This is a hard fault
that must be reset.
– Inverter programming or operational interface malfunction.

ample is a broken belt or coupling.
70, 76, 79, 81, 82, Errors exist in the programmed or operational configuration of the
91 inverter.
60, 90, 192 Required system operational feedback (signal or sensor) is not re-
sponding as expected for correct system operation.
30, 31, 32 One or more of the output phases from the inverter to the motor are
open.
99 Motor is operating in stall region and not able to accelerate.
