Cyclic set value
transmission to
the fieldbus
The active mains rectifier is able to exchange cyclic data with the master control. If this
data exchange is not within a defined time period, the device will generate the errors „Ac-
tual values are not received in time“ or „No data available at the moment“.
Temperature of
device interior
This monitoring function checks the temperature in the interior of the device.
m
If the temperature is higher than the warning threshold, then the controller generates a
warning.
m
If the temperature is too high, then the pulses are inhibited immediately.
Heat sink
temperature
This monitoring function checks the temperature of the heat sink.
m
If the temperature is higher than the warning threshold, then the controller generates a
warning.
m
If the temperature is too high, then the pulses are inhibited immediately.
Signal bus
At axis units all power units are linked together via a so called „signal bus“. The bus sig-
nals can be polled and set by every client device, including the mains rectifier unit.
The mains active rectifier can report to the axis units via this bus
m
Ready-to-operate for drive
This way, the individual axes can react to this signal.
Signal bus - Mains rectifier unit ready-to-operate
Shows when the mains rectifier unit is in the „ready-to-operate“ state. This signal is gen-
erated after reaching the value U
DC link actual
= U
DC link set value
- 10 V.
In case of power supply errors or power supply failure, the ready-to-operate signal is can-
celed again. The axis units react to this with error state.
Signal bus - Malfunction
The „Malfunction“ signal is an input for mains rectifier unit and active mains rectifier unit.
This signal is not evaluated by the active mains rectifier at the moment.
