    Hello All
    Has anyone used one of the JMC iHSV57-30-18-36-21-38 180watt servo motors on a Z axis ball screw (with a standard 2.2kw spindle motor) or similar without a brake fitted. I was wondering if the weight of the spindle motor would be enough to turn the ball screw and drop the motor down to the work table and cause damage to any bits in the spindle collet when the system is powered down?

    Cheers
    Andrew
