result. The time interval value is set in increments of 0.01 ms. For example, for the pa-

rameter value equal to 100, data are transmitted through bit-serial interface with a period

of 0,01*100 - 1 ms.

If the Trigger Sampling mode is selected, the 'sampling period' parameter de-

termines the division factor for the external synchronization input. For example, for the

parameter value equal to 100, data are transmitted through bit-serial interface when

each 100th synchronizing pulse arrives at IN input of the sensor.

Note 1. It should be noted that the 'sampling mode' and 'sampling period' para-

meters conlrol only the transmission of data. The sensor operation algorithm is so built

that measurements are taken at a maximum possible rate determined by the integration

time period, the measurement results Is sent to buffer and stored therein until a new re-

sult arrives. The above-mentioned parameters determine the method of the readout of

the result form the buffer.

Note 2. If the bit-serial interface is used to receive the result, the time required

for data transmission al selected data transmission rate should be taken into account in

the case where small sampling period intervals are used. If the transmission time ex-

ceeds the sampling period, it is this time that will determine the data transmission

10.2.3. Line correction parameter

Is intended for correction of encoder linearity (parameter changing can decrease

encoder accuracy).

10.2.4. Zero position parameter

is intended for assign of sensor's Zero Point
