2.2 List of parameters
r1114 CO: Setpoint after the direction limiting / Setp after limit
Access level: 3
Can be changed: -
Unit group: 3_1
Min
- [rpm]
Description: Displays the speed/velocity setpoint after the changeover and limiting the direction.
p1115 Ramp-function generator selection / RFG selection
Access level: 3
Can be changed: T
Unit group: -
Min
0
Description: Sets the ramp-function generator type.
Value: 0:
1:
Note: Another ramp-function generator type can only be selected when the motor is at a standstill.
r1119 CO: Ramp-function generator setpoint at the input / RFG setp at inp
Access level: 3
Can be changed: -
Unit group: 3_1
Min
- [rpm]
Description: Displays the setpoint at the input of the ramp-function generator.
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
Note: The setpoint is influenced by other functions, e.g. skip (suppressed) speeds, minimum and maximum limits.
p1120[0...n] Ramp-function generator ramp-up time / RFG ramp-up time
Access level: 1
Can be changed: C(1), U, T
Unit group: -
Min
0.000 [s]
Description: The ramp-function generator ramps-up the speed setpoint from standstill (setpoint = 0) up to the maximum speed
(p1082) in this time.
Dependency: Refer to: p1082, p1123
Note: The ramp-up time can be scaled via connector input p1138.
The parameter is adapted during the rotating measurement (p1960 > 0). This is the reason that during the rotating
measurement, the motor can accelerate faster than was originally parameterized.
For U/f control and sensorless vector control (see p1300), a ramp-up time of 0 s does not make sense. The setting
should be based on the startup times (r0345) of the motor.
