sistors is the reason, e.g. by a short-circuit of the motor terminals, and a controlled shut-down
procedure follows, which shuts down the transistor and generates an error message.
This monitoring feature can be reset by a controller reset.
For display and message resetting, see controller description.
y Auxiliary voltage supply monitoring
The power unit auxiliary voltage supply is monitored and generates an error message on appear-
ance of a fault.
This monitoring feature can be reset by a controller reset.
For display and message resetting, see controller description.
y Supply monitoring
Mono unit monitoring has no direct influence on the power unit.
The ready for use message of the mono unit, terminal X99A and X99B connection 5 and the reserve
circuit connection 6 is transferred, free of potential, to the controller cassette, where it is processed
(see controller description).
y Cooling element temperature monitoring
The power unit has no temperature monitoring feature of its own, as the cooling element temperature
is not greatly time-critical.
The cooling element has a linear temperature sensor which passes measurements on to the con-
troller. Temperature monitoring is thus taken over by the controller (see controller description).
Ready for use
All messages from monitoring motor-side power unit are stored there. The power unit is "Ready for use"
if no message is generated or stored. The ready for use message is sent to the controller via the con-
troller’s connection plug.
The controller reacts with a pulse stop if a message is generated.
NOTE
To guarantee recovery of the transistor after switching off due to overcurrent, the error message
can only be reset after 5 seconds (typically, 10 seconds).
NOTE
After connecting the 24 V supply voltage and the main voltage the ready for use signal is gener-
ated within 5 sec. by the power unit.
