SK 54xE – Users Manual for Frequency Inverters
64 BU 0505 GB-1013
2.13 Setpoint card ± 10V
The analog inputs of series SK 500E frequency inverters size 1 to
4 can only process unipolar setpoints (0 … 10V; 0/4 20mA) with
reference to GROUND.
If a bipolar setpoint (analog difference signal (-10V … + 10V)) is
available, this must be converted to a 0 … 10V signal by means of
a setpoint converter. In this case, the appropriate module is
available from NORD. This module is suitable for snap-on rail-
mounting and should be installed near to the frequency inverter in
the control cabinet. For further details, please refer to the
supplementary instructions for the setpoint converter.
Note: Frequency inverters of size S5 and above can process both unipolar and bipolar
setpoints by means of configuration with DIP switches.
