4.5.5 Signal Bus
The signal bus is a connection between the supply unit and the connected axes in the DC
link network. The ready for use signal of the supply is signalized to the connected axes
via this connection.
4.5.5.1 Messages on the Signal Bus
The following matrix shows which signals can be reported and evaluated by which type
of device.
Key:
NGR Mains rectifier unit
NAT Add-on unit with DC link supply only
BM33xx b maXX 3300
Out The unit can set the signal
In The unit must evaluate the signal
The signals are active HIGH. A disjunction is implemented via the cabling. This means
the signal is set to HIGH as soon as at least one connected device has set the signal to
HIGH.
The signals in the devices are monitored at 1 ms intervals.
4.5.5.2 Supply Ready for use
This signal is generated by external supplies. The connected axes evaluate this signal.
The signal indicates that the supply unit is in the ready for use state and the DC link is
supplied. In the event of supply errors (e.g. power supply failure), the output of the ready
fur use signal is stopped. If the signal is not available, an error is generated at the con
-
nected axes units.
4.5.5.3 Chopper Resistor On
This signal activates the chopper resistors of several supplying devices simultaneously.
Both mains rectifier unit and mono units provide a chopper resistor connection and an
own monitoring of the DC link voltage. If the DC link voltage exceeds a fixed threshold,
the chopper resistor is switched on.
The axis units monitor also the DC link voltage and can be configured to generate the
Chopper Resistor On
signal. If this signal is set, the chopper resistor is switched on at
the mains rectifier unit.
