Display RemedyCause
OUE Mains overvoltage Mains voltage > 460V or 550V (500V variant) Reduce mains voltage with a preconnected
transformer or
use a controller with a higher mains
connection voltage.
P03 Following error Angle difference between set and actual
position is larger than the following error limit
set under C255
Drive cannot follow the digital frequency (I
max
limit)
Extend following limit with C255
Switch-off monitoring if required (C119/C120)
Enable drive (Ctrl. enable)
Check drive dimensioning
P13 Angle overflow Angle controller limit reached
Drive cannot follow the digital frequency (I
max
limit)
Enable drive
Check drive dimensioning
PER Program interference A fault in the program sequence was detected Send controller with data (on diskette) to
Lenze
PR Parameter reset After switching on, a change in the software
version has been detected.
Automatic loading of factory setting.
Set the required parameters and save settings
under C003.
PR1 ... PR4 Parameter set error Fault when reading a parameter set
CAUTION:
The factory setting is loaded automatically
Set the required parameters and save settings
under C003.
Sd1 Ta c h o f a u l t Short circuit or interruption of tacho cable Check tacho cables for short-circuit or
interruption and remove fault
Sd2 Resolver fault Resolver cable interrupted Check resolver cable for open circuit
Check resolver
Acknowledge fault by mains switching
Sd3 Encoder fault at Dig_In 1 Incremental encoder or digital frequency cable
interrupted at X5
Input X5 PIN 8 not assigned
Check cable for open circuit
Assign input X5 PIN 8 with encoder potential
or switch off monitoring (C119 / C120)
Sd4 Encoder fault at Dig_In 2 Incremental encoder or digital frequency cable
interrupted at X9
Input X9 PIN 8 not assigned
Assign input X9 PIN 8 with encoder potential
or switch off monitoring (C119 / C120)

Tacho, resolver or fieldbus connection are
interchanged
Change tacho, resolver or fieldbus connection
