17. SPEED GROUP “S”.
SP1.# * (S100.#) VelocityProportionalGain
SP2.# * (S101.#) VelocityIntegralTime
Function : Value of the proportional/integral action of the speed PI.
Valid values: SP1: 0..16384 RMS milliAmperes / rpm.
SP2: millisecond
SP4.# * (S211.#) VelocityAdaptationProportionalGain
SP5.# * (S212.#) VelocityAdaptationIntegralTime
Function: Adapting the proportional / integral of the PI at low speeds.
SP4 is the multiplying factor applied to SP1 when the motor moves at low speed. SP5
is the multiplying factor applied to SP2 at low speeds.
Units: Deci% (thousandths)
Valid values: 25 .. 400% In other words, the PI action at low speeds can go from 25% to 400% of
that at high speeds.
SP4*SP1 / 1000 must be smaller than the maximum value of SP1.
SP5*SP2 / 1000 must be smaller than the maximum value of SP2.
Default value: 100% (constant proportional / integral action at any speed)
SP6.# O (S209.#) VelocityAdaptationLowerLimit
Function: Is the upper limit of the speeds considered "low".
Valid values: Must be smaller than: SP7 (VelocityLoopUpperAdaptationLimit) rpm.
Default value: 10% of SP10 (VelocityLimit) rpm.
SP7.# O (S210.#) VelocityAdaptationUpperLimit
Function: Is the lower limit of the speeds considered "high".
Valid values: Must be: smaller than SP10 (VelocityLimit) rpm.
greater than SP6 (VelocityLoopLowerAdaptationLimit)rpm.
Default value: 80% of SP10 (VelocityLimit) rpm.
SP10.# O (S91.#) VelocityLimit
Function: Maximum value to be assumed by SV7 (VelocityLoopUpperAdaptationLimit).
If SV2 (VelocityFeedback) is 12% greater than this parameter, error 200 is generated
"overspeed"
Valid values : 0..10000 (depends on the motor connected) rpm.
Default value: 110% of SP12 (NominalMotorSpeed); SP11 (MaximumMotorSpeed) rpm.
SP11 FMA (S113) MotorMaximumSpeed
Function: Maximum speed attainable by an asynchronous motor
Valid values: Smaller than SP10 (otherwise, it issues 500-3-)
