3010 !! Inverter fault !! Current asymmetry W IF>C-asymmetry W - This fault can occur only at inverters with several converter systems con-
nected in parallel, if the current of one system is so asymmetric in phase
W, that the system becomes overloaded. Check whether the motor supply
lines are set up symmetrically and if all motor connections are put on cor-
rectly and reliably tightened. In case you find no discrepancies please
inform our service station.
3011 !! Inverter fault !! Commun.uP->DSP IF>Comm.uP->DSP - Communication C161 (processor) to DSP (Digital Signal Processor) inter-
fered. Contact our service station; if necessary, replace the defective
PCBs.
3012 !! Inverter fault !! Reset uP-Program Reset uP-Prog. - Fault in the C161-program (e.g. stack overflow, wrong access to address
etc.) Contact our service station; if necessary, replace the defective PCBs.
3013 !! Inverter fault !! Reset uP-Commun. Reset uP-Comm. - Fault in the communication with processor C161 (reset by DSP) Contact
our service station; if necessary, replace the defective PCBs.
3014 !! Inverter fault !! Reset uP-Watchdog Reset uP-W-D. - Fault in the C161-program with release of Watchdog. Contact our service
station; if necessary, replace the defective PCBs.
3015 !! Inverter fault !! Reset uP-Interrupt Reset uP-Int. - Fault in the C161-program owing to faulty interrupt-release. Contact our
service station; if necessary, replace the defective PCBs.
3016 !! Inverter fault !! Commun.DSP->uP IF>Comm.DSP->uP - Communication DSP (Digital Signal Processor) to C161 (processor) inter-
fered. Contact our service station; if necessary, replace the defective
PCBs.
3017 !! Inverter fault !! Current transformer IF>CurrentTransf. - Hall-sensors –T1, 2, 3 defective. Recheck the plug at the sensors for dis-
connection. If necessary, contact our service station.
3018 !! Inverter fault !! Power unit unknown IF>Pow.Sec. unkn. - Coding of power section is
unknown, (control electronics, plug connections,
wrong wiring, existent type of device not supported by this software); Con-
tact our service station.
3019 !! Inverter fault !! Wrong power unit IF>Pow.Sec. wrong - Coding of power section is not correct, (control electronics, plug connec-
tions, wrong wiring, existent type of device not fitting the originally parame-
terized control electronics); contact our service station.
3020 !! Inverter fault !! Temperature inside IF>Temp.inside low Fault temperature sensor for inverter interior. KTY82-110, -R2 on PCB –
Control electronics has a short or a disconnection.
Recheck sensor –A1-R2, replace it if necessary.
3021 !! Inverter fault !! Temp.Sensor Cool.1 IF>TmpSens.Cool.1 low Fault in temperature sensor for dissipator 1. With compact devices: ther-
mistor –B1 to input of PCB Driver –A12- X15:1-2 has a short or a discon-
nection. With cabinet mount devices: thermistor –B1 to input of PCB
Signals –A13- X51:1-2 has a short or a disconnection.
Recheck sensor B1, replace it if necessary.
