Troubleshooting and fault elimination
Cause
Mains voltage > 460V or 550V (500V variant) Reduce mains voltage with a preconnected
Angle difference between set and actual
position is larger than the following error limit
set under C255
Drive cannot follow the digital frequency (I
limit)
Angle controller limit reached
Drive cannot follow the digital frequency (I
limit)
A fault in the program sequence was detected Send controller with data (on diskette) to
After switching on, a change in the software
version has been detected.
Automatic loading of factory setting.
Fault when reading a parameter set
CAUTION:
The factory setting is loaded automatically
Short circuit or interruption of tacho cable
Resolver cable interrupted
interrupted at X5
Input X5 PIN 8 not assigned
interrupted at X9
Input X9 PIN 8 not assigned
Interruption of the master current selection,
I < 2mA

Tacho, resolver or fieldbus connection are
interchanged
Overload / short-circuit terminal 20
–15 V supply defective
Remedy
transformer or
use a controller with a higher mains
connection voltage.
Extend following limit with C255
Switch-off monitoring if required (C119/C120)

Set the required parameters and save settings
under C003.
Check tacho cables for short-circuit or
interruption and remove fault
Check resolver cable for open circuit
Check resolver
Acknowledge fault by mains switching
Check cable for open circuit
Assign input X5 PIN 8 with encoder potential
or switch off monitoring (C119 / C120)
Assign input X9 PIN 8 with encoder potential
or switch off monitoring (C119 / C120)
Remove interruption of the set-value cable or
select master selection 0...20 mA under C034
