108Ki speedoffset accel.This gain value is effective only at low speeds. This value is added to the Iterm gain in LF.32 to provide greater control and more stability.This offset acceleration gain will assist the motor in catching the load duringstarting. It is especially important for high efficiency geared or gearlessapplications. Values of 2,000 to 5,000 are useful.The offset deceleration gain will allow the system track the command speedtightly at low speed. Often lower values are required than for starting. Valuesof 500 to 2,000 are useful.Unit: 1Value range: 0...8000Default setting: 3000 Accel. , 1000 Decel.The offset gain value is tapered off beginning at about 8 ft/min and theoffset reaches zero at 24ft/min. The corner speeds can be adjusted throughparameters US.20 and US.21.Refer to section 5.12.3 for adjustment information on A.LF.33 and d.LF.33.Ki speedoffset decel.The peak torque limit prevents the motor from exceeding its breakdown torquelimit. If the torque limit is reached, the acceleration process will take longerwith a full load. This can also cause the car to over shoot the floor duringdeceleration. This value can be raised.Default Setting: 150%The maximum output current is limited to the following:Max Current = (0.LF.36/ LF.17) x LF.12The maximum output current is ultimitely limited to the drive’s peakcurrent rating, regardless of how high the 0.LF.36 maximum torque maybe set. Refer to Sections 2.1 and 2.2 for ratings.The low defaults setting is to protect the motor from excessively highcurrent which may occur during the commisioning process if thereare incorreect parameter settings (e.g. motor data incorrect, encoderA/B phasing or ppr incorrect, encoder position for PM synchronousmotor incorrect, etc.) The default settings should be sufficient to enableinspection operation with empty car. Under normal high speed operation,this value will likely need to be increased, typically in the range of 200-250% of rated motor torque.Maximum torqueParameter Description - Control Settings
