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.
