DI6 (PIN13) PTC sensor input mode.
It is possible to connect a PTC sensor in the digital input 6 (DI6) so that the equipment acts from a
temperature (resistance) value associated to motor’s temperature and to allow enabling cooling or stop
motor running. It must be considered that sensor resistance does not exceed trigger point (pass from 1
to 0) of the DI6 when motor is under normal conditions of operation temperature. Cable ground screening
must be connected only in one end.
AI2/AO2 (PIN19/25) pulse input/output mode.
Both analogue input and output 2 can be configured as pulse input/output. To do so, bridge J21 must be
connected in the position indicated in the table above and, besides, they must be connected to GND
(PIN 14).
