Description

The subindices have the following function:

  • 01h: Winding resistance. Float value, shown here as UNSIGNED32. Is determined by Auto setup.
  • 02h: Winding inductance. Float value, shown here as UNSIGNED32. Is determined by Auto setup.
  • 03h: Interlinking flux. Float value, shown here as UNSIGNED32. Is determined by Auto setup.
  • 04h: Switch-on speed in RPM. Closed loop ( sensorless) is activated above this speed if no sensors were detected by Auto setup.
  • 05h: Switch-off speed in RPM. Closed loop ( sensorless) is deactivated below this speed if no sensors were detected by Auto setup.
