reference signals. The sum of these reference signals defines the actual reference.
Function:
Digital inputs and programmed digital outputs are pre-programmable for operation either in PNP or
NPN systems.
Action on positive directional pulses (↕). PNP systems are pulled down to GND.
Action on negative directional pulses (↕). NPN systems are pulled up to + 24 V, internally in the
frequency converter.
Function:
Defines terminal 27 as a digital input.
Defines terminal 27 as a digital output.
Function:
