If drive is unable to drive (or is set deliberately to limit current) below motor ratings, it will cause the obtainable peak torque to be reduced. The reduction is proportional to the current reduction. For example, if motor is rated for 30A and drive can supply 20A, then torque is reduced by ratio 20/30 thus maximum obtainable torque is 67% of motor maximum rating. | If drive is unable to drive (or is set deliberately to limit current) below motor ratings, it will cause the obtainable peak torque to be reduced.

{{tip|In many practical machines, maximum torque is not required which makes even undersized drive suitable. Drive or motor will not have any reliability issues by that mismatch.}} | {{tip|In many practical machines, maximum torque is not required which makes even undersized drive suitable.
