3. Controller Functions
3.15.2 Gear Change via an External Controller
The controller supports the gear change by the NC by:
• signalling the gear change "ready" stage (N < N
min
)
• and oscillating the speed of the motor shaft.
The four parameter records enable the drive to be optimized according
to the reduction stage.
