¹ Without connectors/varies depending on mounting position
² Without cooling connectors/varies depending on pre stage and motor dependent adapterplate
³ Values are subject to variations of +-10%.
⁴ With negative gear ratio, output turns in opposite direction to input; with positive gear ratio, output turns in same direction as input.
