SINAMICS G120 Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
Description: Sets the ramp-function generator type.
Value: 0: Basic ramp-function generator
1: Extended ramp-function generator
Note: Another ramp-function generator type can only be selected when the motor is at a standstill.
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.
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 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), ramp-up times of 0 s are not expedient. The setting
should be based on the startup times (r0345) of the motor.
Description: The ramp-function generator ramps-down the speed setpoint from the maximum speed (p1082) down to standstill
(setpoint = 0) in this time.
Further, the ramp-down time is always effective for OFF1.
Dependency: The parameter is pre-assigned depending on the size of the power unit.
Refer to: p1082, p1123
Note: For U/f control and sensorless vector control (see p1300), ramp-down times of 0 s are not recommended. The set-
ting should be based on the startup times (r0345) of the motor.
