Description: Sets the ramp-down time for the internal ramp-function generator for the motorized potentiometer of the technology
controller.
Dependency: Refer to: p2247
Note: The time is referred to 100 %.
When the initial rounding-off is activated (p2230.2 = 1) the ramp-down is correspondingly extended.
Description: Displays the effective setpoint after the internal ramp-function generator for the motorized potentiometer of the
technology controller.
Dependency: Refer to: r2245
Description: Sets the mode for using the technology controller output.
Value: 0: Technology controller as main speed setpoint
Dependency: p2251 = 0 is only effective if the enable signal of the technology controller is interconnected (p2200 > 0).
Description: Sets the configuration of the technology controller.
Dependency: For bit 04 = 0:
The setting is only effective when the PID controller is deactivated.
Caution: For bit 04 = 1:
The PID controller can oscillate if the ramp-up and ramp-down times of the speed setpoint channel are not taken into
account when setting controller parameters p2280 and p2285.
