ENCB Incremental encoder phase B input.
ENC GND Encoder negative power supply.
NLC Main contactor coil output. The coil is driven to
negative reference.
PLC/PAUX Positive of the LC and Auxiliary coil.
NAUX Auxiliary coil output. The coil is driven to negative
reference.
SAFETY OUT In the COMBI configuration it is connected to SAFETY
IN (CNA#11) of traction controller.
It can also be used to drive an external load to
negative reference when the pump motor is driven.
The maximum current load is 1 A. In case of inductive
load it is suggested to use a free-wheeling diode
across the load (with cathode connected to +Batt)
CAN-L Low level CAN-BUS voltage I/O.
CAN-H High level CAN-BUS voltage I/O.
PTHERM Input for motor temperature sensor. It is possible to
use a digital or analogue (PTC) sensor.
NTHERM -Batt.
PCLRXD Positive serial reception (Not used: it can be
disconnected).
NCLRXD Negative serial reception.
PCLTXD Positive serial transmission.
NCLTXD Negative serial transmission.
GND Negative console power supply.
