3.6.6 PID

3.6.6.1 Speed PID Control

Speed PID Control maintains a constant motor speed regardless of the changing load on the motor.
1-00 Configuration Mode
[0] Speed open loop
[1] Speed closed loop
[2] Torque
[3] Process
[4] Torque open loop
[5] Wobble
[6] Surface Winder
[7] Extended PID Speed OL
[8] Extended PID Speed CL
Table 3.1 Control Configurations with Active Speed Control
"N.A." means that the specific mode is not available at all. "Not Active" means that the specific mode is available but the Speed Control is not
active in that mode.
NOTICE
The Speed Control PID works under the default parameter setting, but tuning the parameters is highly recommended to
optimise the motor control performance. The 2 Flux motor control principles are particularly dependant on proper
tuning to yield their full potential.
Table 3.2 sums up the characteristics that can be set-up for speed control. See VLT
Programming Guide for details on programming.
