4 REPRESENTING THE REFERENCE VALUES IN USER UNITS
Information that you will find in
this chapter …
This chapter gives you information on:
• what user units are
• how to scale your reference value in user units
User units
To simplify presentation, reference values can be indicated in user units in the Comfort
Reference Value application (e.g., bottles per second on a bottle conveyor belt). All
ratios of the motor speed are covered by this.
The user units are calculated in the Comfort Reference Value Assistant. Since
calculation depends on the type of reference value used, go to page "1. Type of
Reference Value" first and select one of the options offered there. After that you can
perform the calculation on the next page.
Calculation of each type of reference value is described in a separate section below.
NOTE
Remember that scaling only has to be performed when you want to present display
values in user units.
If presentation in rpm units is sufficient, the scaling described in the next few sections is
unnecessary. If this is the case, skip chapter 4 and continue reading in chapter 5.
4.1 User Units with a Speed Reference Value
Information that you will find in
this section …
This section describes how to scale a speed reference value in user units. Before you
can begin scaling you must have activated the speed reference value on page 1 of the
Assistant.
Scaling the reference value
Figure 4-1 shows page 2.1 of the Assistant. It presents the organization of a machine
with motor, gear unit and other ratios.
