# Load inertia (P-AXIS-00391)

P-AXIS-00391 | Load inertia
Description | To set up acceleration feedforward with additive torque command value, the total load inertia of the motor must be configured here. The total load inertia is the inertia of the motor itself and the inertia of the load related to the motor shaft. In case of a translatory moved axis, the moved masses must be converted to an equivalent inertia related to the motor shaft.
