3.2.2.3 - Motor current limits & Current Loop
The parameters defining the current limitation to be applied to the motor are the following:
- Motor Max. Current 0x6073
- Motor Rated Current 0x6075
The motor parameters Motor Peak Current (0x6410-10) and Motor stall Current (0x6410-9) will be used for
calculating the internal limitations of the drive according to the drive maximum and rated currents (0x6510).
The values of the drive internal limitations can be displayed by object 0x30F4.
The current loop gains are accessible in object 0x60F6.
Object 0x3411 allows:
- calculating the current loop gains according to the motor parameters and the drive specifications:
Parameters:
Inductance (0x340F)
Drive Max. current (0x6510-1)
Results:
Current Loop Gains (0x60F6)
Object 0x3412 allows:
- calculating the drive current limitations according to the motor and drive currents (0x6510):
Parameters:
Motor Peak current (0x6410-10)
Motor Stall current (0x6410-9)
Drive Max current (0x6510-1)
Drive Rated current (0x6510-2)
Results:
Motor Max current (0x6073-0)
Motor Rated current (0x6075-0)
The input parameters must be previously defined.
