6.5 "Speed control" mode
6.5.1 Description
The following functions are available:
ƒ Setpoint generation via ramp generator (limit function)
ƒ Speed detection via angle encoder by differentiation
ƒ Speed control with appropriate input and output signals
ƒ Limitation of speed setpoint (via PROFIBUS or analog input)
ƒ Monitoring of actual speed (velocity controller)
