NOTE
Siemens AG 6SE7087-7KN50
SIMOVERT MASTERDRIVES
In the basic version, the unit has the following control connections on
the CUMC:
♦ Serial interface (RS232 / RS485) for PC or OP1S (interface 1)
♦ One serial interface (USS bus, RS485) (interface 2)
♦ One control terminal strip 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 ground of the control connections is connected inside the unit with
the protective conductor (ground) – (PELV electrical circuit).
