Copley Controls has introduced the ServoTube brake, a new cost-effective solution for controlled deceleration and parking of vertical axes during power-down and power fail conditions. The highly compact IP67 rated brake provides a holding force of 200 N (45 lb), securely supporting the ServoTube 25 when a machine or production line is powered down.
The ServoTube is particularly suited to use with Copley Controls' own Xenus CANOpen drive. The brake becomes operational when the drive's dedicated normally open brake contacts become closed. Because the normally open contacts are solenoid operated, the brake can be operated as part of a programmed parking operation or as an automatically engaged fail safe in the event of power failure.
A clever unlocking mechanism is used by the new brake that eliminates the problems that are often experienced with brakes jamming or even damaging the rod. Downtime introduced by jamming brakes, not to mention replacing parts is a serious and often neglected issue.
