Analog inputs, terminals O, O2 and OI
You can specify the setpoint frequency through three analog
inputs:
• Terminal O: 0 to 10 V
• Terminal O2: –10 V to +10 V
• Terminal OI: 4 to 20 mA
The reference potential for the analog inputs is terminal L.
Frequency setpoint definition
By default, the frequency setpoint is defined through voltage input
O (0 to +10 V). Alternatively, you can enter the setpoint value
through one of the other analog inputs or a combination of two
analog inputs. To do this, you must configure a digital input with
the AT function (a Section “Analog input changeover (AT)“,
Page 73). The two inputs are specified under PNU A005 and
A006.
The table below shows how you can link analog inputs O, O2 and
OI with PNU A005 and A006.
