IL.KPLOOKUPVALUE

Description

This parameter sets the value at the current index into the Current Loop Gain Scheduling Table. The table is 256 records long, spanning 0 A to 1.62 * DRV.IPEAK. The value can range from 0% to 100% and determines what percentage of IL"Instruction list" This is a low-level language and resembles assembly.KP will be applied to the current loop.

If the feedback deviceA process whereby some proportion of the output signal of a system is passed (fed back) to the input. In automation, a device coupled to each motor to provide indication of the motor's shaft angle, for use in commutating the motor and controlling its speed and position supports motor memory (FB1.MEMVER >= 0.03 and MOTOR.AUTOSET = 1) this parameter is read only. Each index value is automatically calculated and set. This calculation depends on the value of MOTOR.LISAT.

If the feedback device does not support motor memory, this parameter is read/write. Each index value must be entered manually. Use the following equation to determine what level of current corresponds to a table index:

IL.CMD = (Table Index/157) * DRV.IPEAK

Example

Assume:

DRV.IPEAK = 9 A

IL.KPLOOKUPINDEX = 100

IL.KPLOOKUPVALUE = 50

IL.KP = 240

When IL.CMD = 100/157 * 9 = 5.73 A, IL.KP will not be 240, but will be 50% * 240 = 120.
