For information on the number of technology objects that may be used, refer to the technical
specifications of the utilized CPU.
A synchronous axis requires twice as many resources as a speed-controlled axis or
positioning axis. You can configure two fewer speed or positioning axes for every
synchronous axis you use.

Speed-controlled axis technology object
The speed axis technology object calculates speed setpoints, taking account of the specified
dynamics, and outputs them to the drive. All movements of the speed axis occur under
speed control. The system takes account of an existing load gear.
A drive is assigned to each speed axis by means of a PROFIdrive frame, or by means of an
analog setpoint interface.
The speed is specified in revolutions per unit of time.
The following figure shows the basic principle of operation of the speed axis technology
