The Spindle Won't Turn - 1500MX

Check the Spindle Belt

Reason: The motor runs, but the spindle doesn’t turn.

1. Examine the spindle belt for wear or damage.
   If the display on the servo drive is on, the belt may be loose or broken. You’ll hear the spindle motor running.

Check Spindle Driver

Reason: There’s no power to the spindle servo drive.

1. Examine the servo drive display: it has power if its indicator lights are on.
   When power is removed, the servo drive display remains active until the internal capacitors dissipate their energy. That usually takes about five seconds.
