-
21.05 Speed share Defines the scaling factor for the speed reference (the speed
reference is multiplied by the defined value).
-8.000 …8.000 Speed reference scaling factor. 1000 = 1
21.09 SpeedRef min abs Defines the absolute minimum limit for the speed reference.
0 … 30000 rpm Absolute minimum limit for speed reference. 1 = 1 rpm
22
22 Speed ref ramp
Speed reference and emergency stop (OFF3) ramp settings.
22.02 Acc time Defines acceleration time as the time required for the speed
to change from zero to the speed value defined by
parameter 19.01 Speed scaling.
If the speed reference increases faster than the set
acceleration rate, the motor speed will follow the
acceleration rate.
If the speed reference increases slower than the set
acceleration rate, the motor speed will follow the reference
signal.
If the acceleration time is set too short, the drive will
automatically prolong the acceleration in order not to exceed
the drive torque limits.
0.000 … 1800.000 s Acceleration time. 1000 = 1 s
