Motor
The motor is actuated by the power section and drives the axis.
The motor can be:
Encoder
The encoder detects movement of the axis. It supplies pulses to the FM 453.
The number of pulses is proportional to the distance traversed. Stepper motor
operation is also possible without the encoder.
CPU
The CPU executes the user program.
Mechanical Trans-
These include not only the axis, but also gear trains and clutch systems.
mission Elements
Peripherals
All other additional equipment is covered by the term peripherals.
Peripherals mainly include:
FM 453 Servo Drive / Step Drive Positioning Module
C79000-G7076-C453-01
A servo motor, e.g. 1FT5
A stepper motor, e.g. SIMOSTEP
Limit switches to limit the positioning range (safety devices).
The programming device/PC is used for:
– Assigning parameters using the software "Parameterize FM 453"
– Programming the FM 453 using function blocks
– Test/startup
