Fault word according to the VIK-NAMUR definition (MELD_NAMUR)
Bit Significance
P no.
0
1 = Control Unit signals a fault
p2051[5] = r3113
1
1 = line fault: Phase failure or inadmissible voltage
2
1 = DC link overvoltage
3
1 = Power Module fault, e.g. overcurrent or overtemperature
4
1 = converter overtemperature
5
1 = ground fault/phase fault in the motor cable or in the motor
6
1 = motor overload
7
1 = communication error to the higher-level control system
8
1 = fault in a safety-relevant monitoring channel
10 1 = fault in the internal converter communication
11 1 = line fault
15 1 = other fault

grams
0
0 = OFF1
The motor brakes with the ramp-down time
p1121 of the ramp-function generator. The con‐
verter switches off the motor at standstill.
p0840[0] =
r2090.0
0 → 1 = ON
The converter goes into the "ready" state. If, in
addition, bit 3 = 1, the converter switches on the
motor.
1
0 = OFF2
Switch off the motor immediately, the motor
then coasts down to a standstill.
p0844[0] =
r2090.1
1 = No OFF2
The motor can be switched on (ON command).
2
0 = Quick stop (OFF3)
Fast stopping
The motor brakes with the OFF3 ramp-down
time p1135 down to standstill.
p0848[0] =
r2090.2
1 = No quick stop (OFF3)
The motor can be switched on (ON command).
3
0 = Inhibit operation
Immediately switch-off motor (cancel pulses). p0852[0] =
r2090.3
1 = Enable operation
Switch-on motor (pulses can be enabled).
4
0 = Disable RFG
The converter immediately sets its ramp-func‐
tion generator output to 0.
p1140[0] =
r2090.4
1 = Do not disable RFG
The ramp-function generator can be enabled.
