Analog Inputs Connection
3.5.6.1
0-5V Input Range
Remarks:
1.
Default input range for analog inputs is 0÷5 V for REF and FBDK. For a +/-10 V range, see Figure 3.14.
2.
The length of the cables must be up to 30m, reducing the exposure to voltage surges in industrial environment.
3.5.6.2
+/- 10V to 0-5V Input Range Adapter
Remark: The length of the cables must be up to 30m, reducing the exposure to voltage surges in industrial environment.

Recommendation for wiring
a)
If the analogue signal source is single-ended, use a 2-wire twisted shielded cable as follows: 1
the live signal to the drive input; 2
connected to the drive ground terminal.
b)
If the analogue signal source is differential and the signal source ground is isolated from the drive GND, use a
2-wire twisted shielded cable as follows: 1
analogue input; 2
is connected only at the drive side, to the drive GND, and is left unconnected at the source side.
c)
If the analogue signal source is differential and the signal source ground is common with the drive GND, use
a 2-wire shielded cable as follows: 1
nd
input; 2
wire connects the source ground to the drive ground (GND); shield is connected only at the drive
side, to the drive GND, and is left unconnected at the source side. The source minus (negative, out-of-phase)
output remains unconnected.
