1-1 Excessive voltage
between artificial neutral
point of the power supply
and PE or the center of the
intermediate circuit
(approx. 190 VDC) and PE
Voltage > 100 V
Short circuit between
IC and PE:
➔ Check connection of inter-
mediate circuit voltage
+380 VDC and 0 VDC to
PE
• CPS3
➔ Check CPS3
– Replace
• System cable ➔ Replace the system cable
• TSE/TUSE
➔ Replace the TSE/TUSE
• Motor
➔ Replace the motor or
DGD-IS
1-2 Excessive current or
short circuit in the
intermediate circuit
Current > 250 A
Check the system cable
between the +380 VDC and 0 V
wires for short circuiting
• System cable short circuit
➔ Replace the cable
• Short circuit TSE/TUSE
➔ Replace the TSE/TUSE
1-3 Temperature of the
cooling element is too high
Temperature of CPS3,
cooling element is > 90 °C
Constant overload CPS3 Excessive number of DGD-IS.
➔ Reduce the number of
PDB-CPS…
Ambient temperature
PDB-CPS… > 40 °C
➔ Improve the ambient condi-
tions
PDB-CPS… is exposed to
other heat sources, i.e. sunlight
➔ Improve the ambient condi-
tions, attach covers if nec-
essary
Heat dissipation from the
PDB-CPS… is inadequate due
to external conditions
➔ Ensure that air can circulate
through the cooling fins
1-4 I²t Error in intermediate
circuit
The intermediate circuit is over-
loaded.
Excessive number of DGD-IS.
➔ Reduce the number of
PDB-CPS…
1-6 The intermediate circuit
voltage is too high
Intermediate circuit voltage
480 VDC
May also occur momentarily
Braking chopper is defective ➔ Replace the CPS3
Excessive number of DGD-IS is
causing the braking chopper to
overload
➔ Reduce the number of
PDB-CPS…
Intermediate circuit capacitors
no longer have sufficient
capacity
Life span exceeded
➔ Replace CPS3
1-7 Intermediate circuit voltage
is too low
Intermediate circuit voltage
<250 VDC
Mains supply is not powerful
enough
Check the mains supply
➔ More powerful mains supply
required
Relay to the switch-on current
limiter is defective and perma-
nently open
➔ Replace the CPS3
Excessive number of DGD-IS.
The voltage drops during
fastening
➔ Reduce the number of
PDB-CPS…
