4.8.4 Voltage/Current Input Selection (Switches)
The analog input terminals 53 and 54 allow setting of input signal to voltage (0–
10 V) or current (0/4–20 mA).
Default parameter settings:
• Terminal 53: speed reference signal in open-loop (see 16-61 Terminal 53 Switch
Setting).
• Terminal 54: feedback signal in closed-loop (see 16-63 Terminal 54 Switch
Setting).
Note:
Disconnect power to the adjustable frequency drive before changing switch
positions.
Step 1. Remove the local control panel (see Figure 4.16.)
Step 2. Remove any optional equipment covering the switches.
Step 3. Set switches A53 and A54 to select the signal type. U selects voltage, I
selects current.

4.8.5 RS-485 Serial Communication
Up to 32 nodes can be connected as a bus, or via drop cables from a common trunk
line to one network segment. Repeaters can divide network segments. Each
repeater functions as a node within the segment in which it is installed. Each node
connected within a given network must have a unique node address across all seg-
ments.
• Connect RS-485 serial communication wiring to terminals (+) 68 and (-) 69.
