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.
