Why is the 8.0 Nm standstill torque significant for motion control?

It enables the motor to hold load positions securely without continuous motion. This is especially valuable in applications requiring precise holding under load, like CNC or robotic arms.

How does the integrated brake on the MHD071B-035-PG1-UN enhance safety?

The built-in 5.0 Nm holding brake prevents shaft rotation during power-off conditions. This ensures safe positioning for vertical loads or emergency stops.

Is the plain shaft design compatible with keyed couplings?

No, plain shafts require clamp or friction-fit couplings rather than keyed ones. This allows backlash-free torque transmission but needs precise alignment.

How does absolute position detection over 4096 revolutions benefit machine setup?

It eliminates the need for homing cycles after power loss or restart. This reduces downtime and simplifies system initialization in automation processes.

Does the MHD071B-035-PG1-UN require a specific mounting orientation due to its cooling system?

Yes, optimal cooling performance may depend on correct orientation and coolant flow direction. Installers must ensure proper integration with the machine’s liquid cooling loop.
