Option
G03
(peripheral board 2) provides in addition to standard
converter terminals:
•
2 analog outputs (AO) 4 to 20 mA/0 to 10 V
•
2 PTC thermistor inputs for ATEX-certified motor temperature
monitoring for motors in hazardous zones (prewarning/trip)
•
PTC thermistor monitoring without contactor through monitor-
ing unit integrated in converter, certified to SIL 1 in accor-
dance with EN 61508
The converter controller processes the signal of the peripheral
board. In the event of excessive motor temperature, or the
function "Safe Torque Off", the converter inhibits the firing signals
of the IGBTs. The voltage supply of the driver stages is also
switched off. These two redundant, diverse and self-monitored
switch-off paths ensure that the power infeed to the motor is
safely interrupted. Further heating or rotation of the motor is
excluded. The converter can only be reset or switched on when
the motor has cooled down sufficiently and the fault has been
acknowledged. When the voltage fails, the converter safely
interrupts the power infeed to the motor, because firing signals
are no longer transferred. If a fault was active at the moment of
power failure, the converter will also be in fault status when
power is restored.
Standard assignment of inputs/outputs
The table below provides an overview of the pre-assignment
function of interfaces in the pin assignments for the "Standard"
application.
