ROTARY AND LINEAR ACTUATOR CABLES: There are 3
cables attached to the Rotary Actuator, the Power Cable,
the Control Cable and the Modbus Cable. (Illustration 15)
The M17 Transfer Conveyor Alignment Actuator only has 2
cables attached, the Power Cable and the Modbus Cable.
Power Cable: The Power Cable sends 48 VDC
Motor Power voltage and 24 VDC Supply voltage to
the Servo Motor connected to the Actuators. The 48
VDC is used to run the Servo Motor. The 24 VDC
supplies voltage to the Control Unit located inside
the Servo Motor.
Control Cable: The Slicer Computer sends
operating and control signals over the Profibus to the
Remote I/O Nodes to operate the Rotary Actuator
Motor. The Control Cable brings Operating and
Control signals from the Remote I/O Node to Control
Unit inside the Servo Motor. These signals tell the
motor when to run, in what direction to run and how
long to run. The Control Units are preprogrammed
with the operating movements and distance.
Modbus Cable: The Modbus Cable is the
communication link between the Slicer Computer
and the Actuator Servo Motors. The Computer sends
basic instructions to the Control Units inside the
Servo Motors, the Control Units send position and
operation a feedback over the Modbus Cable to the
Computer. If there is a fault in the Servo Motor, a
signal is sent to the Computer over the Modbus
Cable. In the case of the M17 Transfer Conveyor
Motor, the control signals are so basic that they are
sent on the Modbus Cable. The Control Cable is not
used.
