✓: The block can be assigned to the runtime group
Analog signal scaling
If you interconnect a physical quantity, e.g. speed or voltage to the input of a free function
block using BICO technology, then the signal is automatically scaled to a value of 1. The
analog output signals of the free function blocks are also available as scaled quantities (0 ≙
0 %, 1≙ 100 %).
As soon as you have interconnected the scaled output signal of a free function block to
functions, which require physical input quantities - e.g. the signal source of the upper torque
limit (p1522) - then the signal is automatically converted into the physical quantity.
The quantities with their associated scaling parameters are listed in the following:
 Speeds
 Voltage values
 Current values
 Torque values
 Power values
 Angle
 Acceleration
 Temperature
