Settings, Configuration
The required or desired axis-specific settings of the power supply of the
device connected by the module bus have to be made in parameter
P-0-0118, Power supply, configuration.
The following settings or definitions can be made:
• signaling of drive errors inside the drive system and reaction to
signaled errors
• handling of undervoltage as error or warning
• signaling of fatal drive errors to the supply for switching power off (if
necessary with DC bus short circuit)
If an individual threshold value is to be used for monitoring with regard to
undervoltage, enter the desired value in
• P-0-0114, Undervoltage threshold.
Otherwise the undervoltage threshold is 75% of the mains voltage crest
value that was measured when the mains was switched in.
If a converter is to be operated as an inverter at a DC bus, the bit for
power supply has to be set in:
• P-0-0860, Control word of power section.
The "Rel1" contact for the mains contactor control circuit has to be
configured. To do this, the status information "supply ready for operation"
from
• P-0-0861, Status word of power section
has to be assigned to the "Rel1" contact of the control section.
The wiring of the "Rel1" contact has to correspond to the data contained
in the documentation of the converter devices!
In the case of converters, the threshold value for the message "mains
undervoltage" can be set in parameter
• P-0-0810, Minimum mains crest value.
If there isn't any value entered, the default setting remains active (see
Parameter Description for P-0-0810)!
For certain converters of the HCS02.1 type it is possible to determine
whether the internal braking resistor is to be switched off and an
externally connected braking resistor is to be activated. The selection is
made in parameter
• P-0-0860, Control word of power section.
If an external braking resistor is to be used, the data required for control
by the converter have to be entered in parameter
• P-0-0858, Data of external braking resistor.
In the case of converters, the reference values for the switch-on/switch-off
thresholds of the braking resistor can be selected. This is done in
parameter
• P-0-0860, Control word of power section.
In accordance with the setting in parameter P-0-0860, the switch-on
threshold can be dynamically increased depending on the load. The
switch-on threshold currently effective is displayed in
• P-0-0833, Braking resistor threshold.
The current load of the braking resistor is displayed in
• P-0-0844, Braking resistor load.
