p3846
Friction characteristic plot ramp-up/ramp-down time
(factory setting: 10 s)
Ramp-up/ramp-down time for automatic plotting of the friction characteristic.
p3847
Friction characteristic plot warm-up period
(factory setting: 0 s)
At the start of automatic plotting, the inverter accelerates the motor up to the speed =
p3829 und keeps the speed constant for this time.
