What is the purpose of the holding brake in the 1FK7086-4CC71-1RB0-Z motor?
The holding brake is an electromagnetic brake integrated into the motor. It engages when power is removed or upon command, preventing shaft rotation and holding the load in position, which is crucial for safety and precision in vertical axis applications.
