In the basic version, the unit has the following control connections on
the CUVC:
♦ Serial interface (RS232 / RS485) for PC or OP1S
♦ A serial interface (USS bus, RS485)
♦ A control terminal strip for connecting up a HTL unipolar pulse
encoder and a motor temperature sensor (PTC / KTY84)
♦ Two control terminal strips with digital and analog inputs and
outputs.
Before the control cables and encoder cables are connected or
disconnected, the unit must be disconnected from the supply (24 V
electronic power supply and DC link/line voltage)!
If this measure is not observed, this can result in defects on the
encoder. A defective encoder can cause uncontrolled axis movements.
The external 24 V infeed and all circuits connected to the control
terminals must meet the requirements for safety separation as
stipulated in EN 50178 (PELV circuit = Protective Extra Low Voltage).
The earth of the control connections is connected inside the unit to the
PE conductor (earth) (PELV current circuit).
