Select the application control principle to be used when a remote reference (that is via analog input or fieldbus) is active. A remote
reference can only be active when parameter 3-13 Reference Site is set to [0] Linked to Hand/Auto or [1] Remote.
Op- Name Description
tion
[0] Speed open Enables speed control (without feedback signal from motor) with automatic slip compensation for al-
loop
most constant speed at varying loads. Compensations are active, but can be disabled in parameter
group 1-** Load and Motor. Set the speed control parameters in parameter group 7-0* Speed PID Ctrl.
[1] Speed closed Enables speed closed-loop control with feedback. Obtain full holding torque at 0 RPM. For increased
loop speed accuracy, provide a feedback signal and set the speed PID control. Set the speed control param-
eters in parameter group 7-0* Speed PID Ctrl.
[2] Torque
Enables torque closed-loop control with feedback. Only possible when parameter 1-01 Motor Control
Principle is set to [3] Flux w/motor feedb.
[3] Process
Enables the use of process control in the drive. Set the process control parameters in parameter groups
7-2* Process Ctrl. Feedb. and 7-3* Process PID Ctrl.
[4] Torque open
Enables the use of torque open-loop mode (parameter 1-01 Motor Control Principle). Set the torque PID
loop
parameters in parameter group 7-1* Torque PI Control.
[5] Wobble Enables the wobble functionality in parameter 30-00 Wobble Mode to parameter 30-19 Wobble Delta
Freq. Scaled.
[6] Surface wind- Enables the surface winder control-specific parameters in parameter groups 7-2* Process Ctrl. Feedb.
