Fatal Warning Diagnostic Messages (E8xxx)
E8025 Overvoltage in power section
Cause
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
Mains supply voltage (alternating input voltage) too
high
No braking resistor connected or connection or cable
defective

Supported by Firmware Variant:
Supported by Supply Unit:
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.
Remedy
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
Check mains supply voltage (alternating
voltage/3-phase)
Connect braking resistor or check connection
