96 Program featuresApplication control Reference rampingAcceleration and deceleration ramping times can be set individually for speed, torqueand frequency reference (Menu - Primary settings - Ramps).With a speed or frequency reference, the ramps are defined as the time it takes forthe drive to accelerate or decelerate between zero speed or frequency and the valuedefined by parameter 46.01 Speed scaling or 46.02 Frequency scaling. The user canswitch between two preset ramp sets using a binary source such as a digital input.For speed reference, also the shape of the ramp can be controlled.With a torque reference, the ramps are defined as the time it takes for the referenceto change between zero and nominal motor torque (parameter 01.30 Nominal torquescale).Variable slopeVariable slope controls the slope of the speed ramp during a reference change. Withthis feature a constantly variable ramp can be used.Variable slope is only supported in remote control.SettingsParameters 23.28 Variable slope (page 215) and 23.29 Variable slope rate (page215).Special acceleration/deceleration rampsThe acceleration/deceleration times for the jogging function can be definedseparately; see section Jogging (page 118).The change rate of the motor potentiometer function (page 121) is adjustable. Thesame rate applies in both directions.A deceleration ramp can be defined for emergency stop (“Off3” mode).
