5.3 Diagnostics
5.3.1 Malfunctions and warnings in DriveManager 5
The parameters P-0031 ErrorStack and P-0033ActualError contain additional
information on an error or warning that has occurred. You can obtain this information via
the "Device state monitor" in DriveManager 5.
NOTE:
You will nd more detailed information in the Operation Manual ServoOne DC
Axis Controller.
If the brake chopper is operated (DC link voltage ≥820V) the power converted in the
braking resistor is integrated.
P=
(820 V)
2
If the brake chopper is not operated, the power is integrated using the value congured
in the parameters for the brake chopper rated power (MON_BrcPnom).
On reaching the shut-off threshold MON_BrcQmax a device error (ErrID=>24,
Location=>01) is triggered and the operation of the brake chopper inhibited.
NOTE:
Any pre-heating of the braking resistor is not taken into account!
5.2.10 Switching on mains supply voltage
NOTE:
Prior to switching on, check the wiring for correct phase angle.
9.
The mains can now be switched on using the main switch. Once the precharging
of the DC link has been completed, the indication on the display in the supply unit
changes from the value 1 to the value 2.
5.2.11 Switching on regulation
10.
After precharging the DC link, the regulation can be enabled by activating the
input ENPO (X4/10). The supply unit now synchronises the regulation with the
mains voltage. The display indicates the value4 during this phase. After successful
synchronisation, the regulation becomes active and the stipulated setpoint for the
DC link voltage is set. The display indicates the value5.
The actual DC link voltage measured is indicated via the parameter P-0332 in the
area "Parameterlist > PSUstatus > Actual values > DCVoltage" in the parameter
tree. If, on average, this value corresponds to the stipulated setpoint, the supply
unit has been successfully placed in operation.
