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 definition is made through the
voltage input (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, configure a digital input with the AT
function (a section “Analog input changeover (AT)”, page 72).
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.
