Setting
1 signal: Technology controller is enabled.
Factory setting: 0
To interconnect the main speed setpoint with the technology controller
output, set p1070 = 2294.
Setpoint for the technology controller.
Example:
p2253 = 2224: Fixed setpoint p2201 is interconnected with the setpoint of
the technology controller.
p2220 = 1: The fixed setpoint p2201 is selected.
