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.
If the maximum speed p1082 changes, p1127 is re-calculated.
If a braking resistor is connected to the DC link (p0219 > 0), then the minimum ramp-down time is automatically adapted
using p1127.
p1130[0...n]
Ramp-function generator initial rounding-off time / RFG t_start_round
Access level: 2
Calculated: -
Data type: FloatingPoint32
Can be changed: T, U
Scaling: -
Dynamic index: DDS, p0180
Unit group: -
Unit selection: -
Function diagram: 3070
Min:
0.000 [s]
Max:
30.000 [s]
Factory setting:
0.000 [s]
Description:
Sets the initial rounding-off time for the extended ramp generator. The value applies to ramp-up and ramp-down.
Note
Rounding-off times avoid an abrupt response and prevent damage to the mechanical system.
Rounding off is not active if the technology controller is used as main speed setpoint (p2251 = 0).
