SIMOVERT MASTERDRIVES
The basic version of the unit is provided with the following control
connections:
♦ external 24V supply, USS bus connection (RS485)
♦ serial interface for PC or OP1S
♦ control terminal strip.
The device must be disconnected from its voltage supplies (24 V DC
electronics supply and mains voltage) before the control and encoder
leads are connected or disconnected!
Failure to observe this advice can result in encoder defects, which may
in turn 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 external 24 V supply must be protected by an m.c.b. in order to
prevent the overloading of printed conductors / components in the
event of a device defect (e.g. a short circuit in the control electronics or
.
a wiring fault)
