page 283.
0032 EFB 2
(FF93)
0307 bit 1
0033 EFB 3
(FF94)
0307 bit 2
0034 MOTOR PHASE
(FF56)
0306 bit 14
Motor circuit fault due
to missing motor
phase or motor
thermistor relay (used
in motor temperature
measurement) fault.
Check motor and motor cable.
Check motor thermistor relay (if used).
0035 OUTP WIRING
(FF95)
0306 bit 15
(programmable fault
function 3023)
Incorrect input power
and motor cable
connection (ie input
power cable is
connected to drive
motor connection).
The fault can be
erroneously declared if
the input power is a
delta grounded system
and the motor cable
capacitance is large.
This fault can be
disabled using
parameter 3023
WIRING FAULT.
Check input power connections.
Check fault function parameters.

CURVE
(FF6B)
0307 bit 4
Condition defined by
3701 USER LOAD C
MODE has been valid
longer than the time
set by 3703 USER
LOAD C TIME.
See parameter Group 37: User load
curve.
0039 UNKNOWN
EXTENSION
(7086)
0307 bit 5
Option module not
supported by the drive
firmware is connected
to the drive.
Check connections.
0040 INLET VERY LOW
(8A81)
0307 bit 6
