Description: Sets the signal source for the minimum limiting of the technology controller.
Dependency: Refer to: p2292
Note: If the technology controller is rotated in a negative direction in mode p2251 = 0, its lower limit p2298 should be
connected to the actual minimum speed r1087.
Description: Sets the signal source for the offset of the output limiting of the technology controller.
Description: Sets the start value for the output of the technology controller.
If the drive is switched on and the technology controller is already enabled (see p2200, r0056.3), then its output
signal r2294 first goes to the start value p2302, before the controller starts to operate.
Dependency: The starting value is only effective in the mode "technology controller as main speed setpoint" (p2251 = 0).
If the technology controller is first enabled when the drive is switched on, a start speed remains ineffective, and the
controller output starts with the actual setpoint speed of the ramp-function generator.
Note: If the technology controller operates on the speed/setpoint channel (p2251 = 0), then the starting value is interpreted
as the starting speed and when operation is enabled, is connected to the output of the technology controller (r2294).
If fault F07426 "technology controller actual value limited" occurs while ramping up to the starting value and if the
associated reaction has been set to "NONE" (see p2100, p2101), the starting value is kept as the speed setpoint
instead of a switch to closed-loop control operation.
Description: Setting to invert the system deviation of the technology controller.
The setting depends on the type of control loop.
Value: 0: No inversion
1: Inversion
Caution: If the actual value inversion is incorrectly selected, then the closed-loop control with the technology controller can
become unstable and can oscillate!
