List of parameters
Note: In order that the output of the technology controller does not exceed the maximum speed limit, its upper limit p2297
should be connected to the actual maximum speed r1084.
In mode p2251 = 1, p2299 must also be connected to the output of the ramp-function generator r1150.
p2298[0...n] CI: Technology controller minimum limit signal source / Tec_ctrl min_l s_s
CU240D-2_DP Access level: 3
CU240D-2_DP_F
Can be changed: U, T
CU240D-2_PN
Units group: -
CU240D-2_PN_F

-
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 con-
nected to the actual minimum speed r1087.
In mode p2251 = 1, p2299 must also be connected to the output of the ramp-function generator r1150.
p2299[0...n] CI: Technology controller limit offset / Tech_ctrl lim offs
CU240D-2_DP Access level: 3
CU240D-2_DP_F
Can be changed: U, T
CU240D-2_PN
Units group: -
CU240D-2_PN_F
Min
-
Description: Sets the signal source for the offset of the output limiting of the technology controller.
Note: In mode p2251 = 1, p2299 must be connected to the output of ramp-function generator r1150 so that the technol-
ogy controller stops when the speed limits are reached (see also p2297, p2298).

0.00 [%]
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 it's output sig-
nal 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 inter-
preted 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.
