Terminal H outputs +10 V (max. 10 mA) to provide the setpoint
voltage for supplying an external potentiometer. Reference point
is terminal L.

All analog inputs and outputs use terminal L as reference
potential and are therefore also connected to the
reference potential of digital inputs 1 to 5.
Circuit example Description
• Frequency reference input (default = 0 to 50 Hz) through
an external potentiometer (recommended fixed resistance
1to5kO).
• Standard circuit
• Frequency reference input (default = 0 to 50 Hz) through
an external 4 to 20 mA current signal.

At the default setting, the input signals at terminals O
(0 to 10 V) and OI (4 to 20 mA) are added to the resulting
frequency reference input. You can select the reference
source with parameter PNU A005 (AT selection) and
activate it through a control signal terminal
(PNU C00x = 16).
