Components of a Positioning Controller
Component
... establish the mechanical and electrical connections
between the S7-400 modules.
... the positioning module. It is controlled by the
S7-400 CPU.
... executes the user program; and communicates with
the programming device and the operator panel via the
MPI interface and with the FM 453 via the backplane
bus.
... converts line voltage (120/230 V AC) to 5 V and
1)
(24 V)
and performs monitoring functions.
... adapts various process-signal levels to the S7-400.
... configures, parameterizes, programs and tests the
S7-400 and the FM 453.
... the interface to the machine. It serves for operation
and monitoring. It is not an absolute prerequisite for
operation of an FM 453.
... actuates the motor.
... drives the axis.
... the path measurement system that detects the current
position of the axis in servo control mode. By compar-
ing the actual position with the applicable setpoint
position, the FM 453 immediately detects discrepan-
cies and attempts to compensate for them.
... includes:
A manual
3 1/2" diskette with:
– Function-block package FCs.
– The "Parameterize FM 453" parameterization
tool.
– Preconfigured interface for the COROS device
