r1149 CO: Ramp-function generator, acceleration / RFG acceleration
Access level: 3
Unit: [rev/s²]
Description: Displays the acceleration of the ramp-function generator.
Dependency: Refer to: p1145
r1150 CO: Ramp-function generator speed setpoint at the output / RFG n_set at outp
Access level: 4
Unit: [rpm]
Description: Displays the setpoint at the output of the ramp-function generator.
p1155[0...n] CI: Speed controller speed setpoint 1 / n_ctrl n_set 1
Access level: 4
Can be changed: T
Min
-
Description: Sets the signal source for speed setpoint 1 of the speed controller.
Dependency: The effectiveness of this setpoint depends on, e.g. STW1.4 and STW1.6.
The signal source of the total setpoint is automatically interconnected to the output of the technology controller
(r2294) if the technology controller is selected (p2200 > 0) and operated in the mode p2251 = 1. If the hibernation
function is activated (p2398 = 1), an interconnection is made to r2397[1].
Refer to: r0002, p0840, p0844, p0848, p0852, p0854, r0898, p1140, p1142, p1160, r1170
Caution: If the technology controller or hibernation function is activated, then it is not permissible to withdraw the parameter
interconnection.
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
p1160[0...n] CI: Speed controller speed setpoint 2 / n_ctrl n_set 2
Access level: 4
Can be changed: T
Min
-
Description: Sets the signal source for speed setpoint 2 of the speed controller.
Dependency: Refer to: p1155, r1170
Note: For OFF1/OFF3, the ramp-function generator ramp is effective.
The ramp-function generator is set (to the setpoint (r1170)) and stops the drive corresponding to the ramp-down
time (p1121 or p1135). While stopping via the ramp-function generator, STW1.4 is effective (enable ramp-function
generator).
r1169 CO: Speed controller, speed setpoints 1 and 2 / n_ctrl n_set 1/2
Access level: 4
Unit: [rpm]
Description: Displays the speed setpoint after the addition of the speed setpoint 1 (p1155) and speed setpoint 2 (p1160).
Dependency: Refer to: p1155, p1160
Note: The value is only correctly displayed at r0899.2 = 1 (operation enabled).
r1170 CO: Speed controller, setpoint sum / n_ctrl setp sum
Access level: 3
Unit: [rpm]
Description: Displays the speed setpoint after selecting the ramp-function generator and adding the speed setpoint 1 (p1155)
and speed setpoint 2 (p1160).
Dependency: Refer to: r1150, p1155, p1160
