The signal interface carries the input and output signals as well as the
24 VDC signal voltage. Signal interface
The controller can be provided with a standardized field bus interface
(e.g. Interbus-S or Profibus-DP). This enables the controller to receive
and execute commands from a master unit. Field bus interface
The encoder interface RS 422 (OPT.2) can be used for implementing an
electronic gear or for rotation monitoring. This depends on the setting of
the parameters P00 and P20. Encoder interface
The oscillator generates the movement frequency for controlling the
stepping motor. The oscillator may be controlled either by an analog
signal (in the range of
±
10 V) if the controller has an analog interface
(ANOZ), or by the digital signal FH/FL of the signal interface, if the
controller does not feature an additional interface in the OPT.1 adapter
slot. The two speeds f
H
and f
L
for oscillator mode via the inputs/outputs
of the signal interface are set on the front panel.
Oscillator
The microprocessor controls all interfaces. The movement profile gen-
erator is activated by the microprocessor. Management processor
Three seven-segment displays indicate positions, parameters, operating
states and any malfunctions. Status display
Three keys are provided on the front panel for operation and error
acknowledgement. Keys
The indexer (movement profile generator) generates a pulse sequence
from the current movement parameters (travel, speed and acceleration).
This pulse sequence is passed on to the power controller. Indexer
The power controller converts the pulse sequence received from the
indexer into a current pattern for controlling the 3-phase stepping motor.
The motor phase current can be set with a front panel parameter. Power controller
