5.7 Operating Modes / OP Modes of the Start/Stop
Interface
The device supports the following operating modes:
Managing Operation

The device generates the init pulse for a connected rotary encoder.

The two init connectors (INIT OUT, /INIT OUT) are configured as outputs.
Managed Operation

An external devices generates the init pulse for a rotary encoder.

The two init connectors (ext. INIT IN, ext. /INIT IN) are configured as inputs.
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 measuring function (distance measurement, angle measurement, or
velocity measurement) can be selected using the "OPERATIONAL MODE"
parameter.
POSITION (distance measurement)
The current position of the position encoder is determined on the basis of a run-
time measurement from the start and stop pulse and can be converted into
another unit using existing scaling parameters (factor, divider, and additive
value), e.g., for the serial readout of the position value in a desired unit.
Interpretation of the measurement result for the distance measurement:
The default setting of the scaling parameters ("FACTOR = 1," "DIVIDER = 1" and
ADDITIVE VALUE = 0") is a position measurement result in micrometers (µm).
For example, to get a position in inches with three notional decimal places, the
"FACTOR" parameter must be set to "10," the "DIVIDER" parameter to "254," and
the "ADDITIVE VALUE" parameter to "0."
