14.13 Technology functions
Description of function
The technology controller is implemented as a PID controller (controller with proportional,
integral, and derivative action).
①
The converter uses the start value when all the following conditions are simultaneously satisfied:
•
The technology controller supplies the main setpoint (p2251 = 0).
•
The ramp-function generator output of the technology controller has not yet reached the start value.

Simplified representation of the technology controller
The technology controller is set as follows:
• Basic settings
The settings required as a minimum are marked in gray in the function diagram:
– Interconnect setpoint and actual values with signals of your choice
– Set the ramp-function generator and controller parameters K
• Output signal of the technology controller
In the factory setting, the output of the technology controller is limited to ± maximum speed.
This limitation must be changed according to the respective application.
Example: The output of the technology controller supplies the speed setpoint for a pump.
The pump should only run in the positive direction.
