Example 3: Driverless Transport System (DTS), forward and

reverse, with incremental encoders

Determine the number of pulses your incremental encoders

deliver per centimetre covered by your vehicle.
The result is dependent on the number of pulses the

incremental encoder delivers per revolution and on the

transmission ratio between the vehicles running wheel and the

frictional wheel on which the incremental encoder is mounted.

How to calculate the number of pulses per centimetre:

The running wheel of a forklift has a diameter of 35 cm.
The frictional wheel on which the incremental encoder is

mounted has a diameter of 3.5 cm.
The incremental encoder used delivers 1000 pulses per

revolution.

Circumference of

forklift wheel = d x

= 35 cm x

= 109.96 cm

One revolution of the forklift wheel corresponds to ten

revolutions of the frictional wheel and thus to 10,000 pulses of

the incremental encoder.
From this the number of pulses of the incremental encoder per

centimetre covered by the vehicle is calculated as:
Pulses/cm = 10,000: 109.96 = 90.94
When configuring the incremental encoder in the PLS/LSI user

software you must thus enter the rounded value 91 under

Pulses per centimetre.

The user software calculates from that figure the maximum

permissible speed of the vehicle.
(How to configure the incremental encoders in the PLS/LSI user

software is described in section 9.7).

The LSI system is configured as follows:

Two PLS sensors connected

Six monitoring areas defined (the protective and warning

fields are configured in stages, as shown in the diagram)

Two incremental encoders connected and configured

Two OSSD outputs and two warning field outputs configured

Six monitoring cases configured (three for forward, three for

reverse)

Any order of monitoring cases
(The circuit diagrams relating to this example are on the next

page.)
