Analog Inputs
This section describes analog inputs for Ultra3000 (Non-Sercos) and
Kinetix 5100 servo drives. Table 26
compares the analog inputs of these two
drives.
The Ultra3000 drive analog COMMAND input can receive a position, velocity,
or current command signal. A 14-bit A/D converter digitizes the signal. The
characteristics of this input are shown in Figure 5
.
