Scaling of the Speed Reference OutputΒΆ

These two parameters are used to scale Speed Reference output of the kernel FB in order to reach the intended velocity by the outputted value and to limit the highest possible output value.

REF_MAX

Highest possible output value of the Speed Reference output. The Speed Reference value that corresponds to the parameter MAX_RPM should be used.

MAX_RPM

Maximum speed of the motor in revolutions per minute.

Example

  • Analog Drive: 1000 rpm at 2 Volts, 3200 rpm at 6,4 Volts (max.)
  • Analog output module: 10 Volts output at digital value 27648
  • REF_MAX = 17695(= 27648 / 10 * 6,4)
  • MAX_RPM= 3200
