MD 2.1 2 1Options for installation and add-on parts Piggy back Overview (continued) If motors cannot be positioned in front

of the gear unit due to space concerns, it is possible to mount the motors piggy back. In addition, other speeds can be driven on the low speed shaft by changing the pulley drive and the drive is protected during high dynamic peak loads from the application. Piggy back versions for gear units are listed here as examples, other sizes on request.
