Reference signal is a signal that will be used as target value in control systems. Typical occurrences of reference signals in GD products are:

  • Position reference
  • Veloicty reference
  • Torque reference

I.e. position reference value may be "1234" which could mean a target position of 1234 mm in some linear actuator. Or torque reference of 5 Nm would mean that motor is asked to produce 5 Nm torque.

Physical reference signal types

Reference signals may have several representations in real world including:

In these cases there will be a conversion between input and output units. For example when using +/-10V reference as velocity reference, the relation betveen types could be 1 Volt per 100 rpm (or any other scale).
