Blocking

monitoring
This monitoring function checks the motor speed and the motor current.

If the following two conditions are met for at least the „Blocking monitoring time“, then the
error message „Drive blocked“ is generated by the controller and the pulses are inhibited
immediately.
m Motor speed = 0
m The motor current output by the device is the same as the set maximal motor current
(current limit).
Signal bus The signal bus is a connection between the supply unit and the connected axis units in
the DC link network. The ready-to-operate signal of the supply unit is signalized to the
connected axes via this connection. Furthermore the signal bus can be used to signalize
an error or a warning to the other connected devices.
Signal bus - Supply unit ready-to-operate
The mains rectifier unit, the active mains rectifier unit and mono units generate this signal.
The connected axis units evaluate this signal.
The signal indicates that the supply unit is in the ready-to-operate state and the DC link
is supplied. In the event of power 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 connected axis units.
Signal bus - Supply unit not ready-to-operate
This signal indicates also the state of the mains rectifier unit. It is required, if axis units will
be operated in a DC link network with several mono units.
In this case it can only be evaluated by the „Power supply ready-to-operate“ signals
whether at least one supplying device is ready, because the signal is a disjunction of the
states of all supplying devices. It can not be recognized whether all supplying devices are
ready.
In order to recognize that at least one supply unit is in state not ready-to-operate, the sig-
nal „Supply not ready-to-operate“
is generated. The evaluation of this signal can be dis-
abled for special applications.
Signal bus - Phase failure
The mains rectifier unit, the active mains rectifier unit and mono units generate this signal
if a phase failure is recognized.
The axis units can operate at phase failure only at mains rectifier units and at mono units.
Several options are selectable for further operations, see parameter 130.10 Power supply
mode.
