The Drive is configured for the signal connections shown in Figure 4–11.
Terminals C4 and C5 can alternatively be configured for connection to a
remote speed-reference current-signal (0 to 20mA, etc). See the
descriptions which follow for terminals C4 and C5.
The functions of the two analog inputs are selected by the user using two
parameters as shown in Table 4–5. Make a note of the parameter settings
for the required functions.
