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 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.
Description: Sets the ramp-down time for the ramp-function generator.
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: Refer to: p1082, p1123
Note: For U/f control and sensorless vector control (see p1300), a ramp-down time of 0 s does not make sense. The setting
should be based on the startup times (r0345) of the motor.
Description: Sets the signal source for bypassing the ramp generator (ramp-up and ramp-down times = 0).
Caution: If the technology controller is operated in mode p2251 = 0 (technology controller as main speed setpoint), then it is
not permissible to disable the interconnection to its status word (r2349).
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
Note: In the case of sensorless vector control, the ramp-function generator must not be bypassed, other than indirectly by
means of interconnection with r2349.
