Notes for DIN6 and DIN7:
Digital inputs DIN6 and DIN7 depend directly on analogue inputs AIN1 and AIN2. This means that the digital functions can only be used if the
analogue functions are disabled (corresponding to the factory setting).

PTC resistor input
Monitoring of motor temperature using PTC
The motor´s PTC resistor (TF) is
connected via the Q8 motor connection.
Use a shielded cable.
Connect a temperature sensor to put the device into operation
mode. As an alternative, you can deactivate the input
function. In this case, however, the thermal monitoring of the
motor is no longer possible.

System bus
NORD-specific bus system for communicating with other devices (e.g. intelligent
option modules or frequency inverters)
Up to four frequency inverters (SK 2xxE,
SK 1x0E, SK 2xxE-FDS) can be operated
on a single system bus.

Brake actuation
Connection and actuation of an electromechanical brake. The FI generates an
output voltage for this, which depends on the mains voltage. The assignment of the
correct brake coil voltage must be taken into account in the selection.
Connected loads:
