3202h Motor Drive Submode Select


Controls the controller mode, such as the changeover between closed loop / open loop and whether Velocity Mode is simulated via the S-controller or functions with a real V-controller in closed loop.

Changeover between open loop and closed loop (see chapter Control modes)

  • Value = "0": open loop
  • Value = "1": closed loop

Toggling is not possible in the Operation enabled state.

Value = "1": Simulate V-controller with an S-ramp: simulate the speed modes through continuous position changes
Value = "1": Switch on automatic brake control.
CurRed (Current Reduction)
Value = "1": Current reduction activated in open loop
AutoAl ( auto alignment)
For the case that operation in closed loop is required (bit 0 in 3202h is set).

Value = "1": The auto alignment process is activated; immediately after switching on, an alignment is determined in open loop and a switch is immediately made to closed loop mode without the encoder index having been seen.

The rotor is moved slightly during this process.

Value = "0": No auto alignment, the motor operates in open loop until the encoder index is seen (maximum one revolution of the motor shaft).

If the incremental encoder used for commutation does not have an index (bit 0 in 33A0h is "0"), an auto alignment is always determined.


only active in operating modes Profile Torque and Cyclic Synchronous Torque

Value = "1": M-controller is active, otherwise a V-controller is superimposed: no V-controller is used in the torque modes for speed limiting, thus object 6080h is ignored; 3210h:3 and 3210h:4 have no effect on the control.

Value = "1": Motor type "BLDC" (brushless DC motor)
Slow ( slow speed)
Value = "1": The slow speed mode is activated ( closed loop must already be activated)
