Frequently Asked Questions
How does natural convection cooling impact the continuous operation of this motor?
The natural convection design allows heat to dissipate without forced air systems. The setup minimizes maintenance and supports long-term continuous duty in enclosed environments.
What is the benefit of having absolute position detection over 4096 revolutions?
The wide detection range enables precise multi-turn tracking without resetting encoders. The feedback system ensures accurate positioning after power interruptions or system resets.
How does a holding brake torque of 70 Nm affect machine safety during power loss?
The high brake torque prevents unwanted shaft movement under heavy load. The braking feature secures the driven mechanism when power or servo control is lost.
Why is the plain shaft with a seal important for industrial applications?
The shaft seal prevents lubricant leaks and blocks dust and fluid ingress. The design enhances bearing life and maintains motor performance in harsh environments.
What installation precautions are needed for side B output connectors?
The output connector requires clearance for cable routing and protection against strain. The correct orientation reduces electrical noise and improves connection durability.
