Fatal Warning Diagnostic Messages (E8xxx)
E8025 Overvoltage in power section
Supported by Firmware Variant:
FWA-INDRV*-
MPH02
VRS-MS
FWA-INDRV*-
MPB02
VRS-MS
FWA-INDRV*-
MPD02
VRS-MS
Supported by Supply Unit:
HMV01
The DC bus voltage is monitored. When the allowed maximum value is
exceeded, the fatal warning E8025 is generated.
Note:
The controller switches the motor to torque-free state in the
case of overvoltage. If the DC bus voltage falls below the
allowed maximum value again, the motor is switched on again.
Note:
Only for HMV: If the warning E8025 persists for more than
2 seconds, the error
F2817 Overvoltage in power section
is
generated.
Cause
Remedy
Energy regenerated to DC bus by mechanical
machine system during braking process was so high
that supply unit couldn
’
t dissipate it during
regeneration time. This caused DC bus voltage to
rise to inadmissible value
Reduce regenerative power by lower acceleration
values
–
or
–
Correct drive dimensioning
–
or
–
Dimension supply unit sufficiently with regard to braking
energy requirements; if dimensioning of available
braking resistor is insufficient, use additional braking
resistor, if necessary
Mains supply voltage (alternating input voltage) too
high
Check mains supply voltage (alternating
voltage/3-phase)
No braking resistor connected or connection or cable
defective
Connect braking resistor or check connection
