NPN outputs
The NPN outputs are internally protected against over temperature and electrostatic discharge. Short cir-
cuit and overload protection is handled directly through the over temperature protection circuitry. The
outputs are able to control ohmic and inductive loads.

a ) The sum of all the output currents of the NPN outputs must not exceed this value.
b ) The NPN outputs are thermally protected against short circuit.
Synchronization signal
Synchronization signals are transmitted differentially according to standard ANSI TIA/EIA-422 (formerly
known as RS422). The signal behavior is based on the signals of an incremental encoder. The signals are
provided directly from the motor control circuit in the machine. The impulse frequency is proportional to
the feed rate of the
EcoCut 3300
. The feed direction (forward / backward) can be recognized by means of
the signal phasing.
The synchronizing signals of the PREFEED interface are synchronized on the left transport unit. E. g. if the
left transport unit stands still, no pulses are transmitted even if the right transport unit is moving. The
synchronizing signals of the "POSTFEED" interface are synchronized on the right transport unit ("LENCB",
"RENCA" and "RENCB" are identical).
