Brake on Motor Option (-BM24, -BM115, -BM230)
The motor shaft-mounted brake can be an advantage because brake torque is multiplied by the belt or gear
reduction and does not interfere with certain rear cylinder-mounting options. A broken drive belt will render the
motor-mounted brake inoperable. Note: This is a static brake, intended only for in-position holding. It should not
be used for routinely stopping a moving load.
