PIN Signal Function Specifications

X1:01 PWR_VP INPUT

Auxiliary power supply / battery “+”

Supply voltage Vs

X1:02 PWR_GND Auxiliary power supply ground Ground of auxiliary power supply

X1:03 DC_LINK_DISCHAR

INPUT HIGH, NOT CONNECTED (n.c.) or module

not supplied with Auxiliary power = DC Link

discharge active

LOW = DC Link discharge disabled

(internal pull-up resistor, external pull-up

resistor required as well)

X1:04 CMN_HALT INPUT/OUTPUT All connected units have to change the signal

mode to „dominant“ if following happens:

The unit is not ready to operate

Error happened

All connected units must be able to process

(read) the signal. In case of recognised

dominant signal, following steps need to be

performed:

The unit must be switched to a defined safe

operation mode

The unit must interrupt the main process unitl

a recessive signal has been recognised

LOW (dominant) = not ready to operate

HIGH (recessive) = ready to operate

X1:05 CMN_TEMP_GND Ground for temperature sensor signal

CMN_TEMP

Internally connected to PWR_GND
