Index Settings:
This register card defines origin and evaluation of the index signals
Mode
Currently not used, reserved for future use.
Index Mode
The cutting pulse necessary with every cut (mandatory) and a print mark or
index pulse from the line (optional) can be applied as a HTL/24V signal to
the digital inputs, or as a TTL/RS422 signal to the SUB-D-connector of the
corresponding encoder input:
Ind. Mode: Cutting pulse source:
Master index source:
0
HTL (Cont.In04, X6 terminal 5)
HTL (Cont.In03, X6 terminal 4)
1
TTL/RS422 (Encoder2, Pin 6/7) HTL (Cont.In03, X6 terminal 4)
2
HTL (Cont.In04, X6 terminal 5) TTL/RS422 (Encoder1, Pin 6/7)
3
TTL/RS422 (Encoder2, Pin 6/7) TTL/RS422 (Encoder1, Pin 6/7)
Slave Index Div. Impulse divider for cutting pulse. Setting to a value n > 1 evaluates only
every nth cutting pulse
Slave Z Offset
Offset register for virtual displacement of the physical cutting impulse
(generated from encoder index or by proximity). Setting in +/- encoder
increments. This register makes superfluous a precise mechanical
adjustment of the location of the pulse (the virtual cutting pulse must be
located exactly in the peak position of tool penetration)
Time Pulse out
Sets the pulse duration of the 12 o’clock pulse output (x.xxx sec) which the
unit generates exactly in the opposite position of the virtual cutting pulse.

Ramps
This register card is designed for future functions and remains currently unused.

Control Loop
Defines the properties of the closed loop position control:
Gain-Correction
Sets the proportional Gain of the position control loop in relation to
positional errors
Sampling Time
Sampling time of the Master frequency input. Used to smoothen the
analogue output with unsteady input frequencies
Gain Torque
Proportional Gain of the torque analogue output. The torque output voltage
is proportional to the differential error during the cut. When the next cut
begins, the torque output starts with the value that has been stored after
the previous cut. When an error higher than the previous error is detected,
the new value will overwrite the previous value.
