Operating modes / OP modes of the Start/Stop interface
The device supports the following operating modes:
• MASTER
- The Init pulse for the connected encoder is generated by the device.
- The two Init connections (INIT OUT, /INIT OUT) are configured as outputs in this case.
• SLAVE
- The Init pulse for the encoder is generated by an external device.
- The two Init connections (ext. INIT IN, ext. /INIT IN) are configured as inputs in this case.
The desired operating mode can be selected in the "General Menu" using the "INIT MODE"
parameter.
The device can also be operated in the following three "Operational Modes". The desired
measurement function (distance measurement, angle measurement or velocity measurement) can be
selected from among by means of the "OPERATIONAL MODE" parameter.
• POSITION (distance measurement)
The current position of the position encoder is determined on the basis of a run-time measurement
consisting of a start and stop pulse and can be converted into another unit, if desired, using the
existing scaling parameters (Factor, Divider and Additive Value) (e.g. for serial readout of the
position value in a desired unit).
Interpretation of the measurement result during distance measurement:
The default setting of the scaling parameters ("FACTOR = 1", "DIVIDER = 1" and ADDITIVE VALUE = 0")
corresponds to a position measurement result in micrometers (µm).
For example, to get a position in "inch" with three fictitious decimal places, the parameter "FACTOR"
must be set to "10", the parameter "DIVIDER" to "254" and the parameter "ADDITIVE VALUE" to "0".
• ANGLE (angle measurement)
For angle measurement, the desired position or angle output value per rotation can be specified by
means of parameter "ROUND LOOP VALUE". This output value is generated as soon as the distance
covered (e.g. circumference), which is set as the reference value in the parameter "CIRCUMFERENCE
(in mm)", is reached. Afterwards the output value starts again at 0 until the covered distance is
reached again. (Round Loop Function!)
Using existing scaling parameters (Factor, Divider and Additive Value), this output value can be
rescaled if desired.
Interpretation of the measurement result during angle measurement:
The default setting ("CIRCUMFERENCE (mm) = 100.000" and "ROUND LOOP VALUE = 360", as well as
"FACTOR = 1", "DIVIDER = 1" and "ADDITIVE VALUE = 0") corresponds to an angle output or position
output of "0...360" (e.g.: degrees) every 100.000 mm.
