The brake prevents gravitational back-drive on vertical axes and secures fixtures during e-stop or power loss, then releases on command. Its commissioning includes verifying transferable holding torque and periodic “grinding-in” procedures when brakes are actuated infrequently.

The elevated inductivity attenuates PWM ripple and torque pulsation for improving low-speed smoothness and mitigating acoustic noise. Its drive tuning should balance current-loop bandwidth with available DC link voltage to maintain dynamic step response under peak-current transients.

The power connector exits on side B per Rexroth type code for allowing alternate routing relative to the encoder plug and terminal box options. It helps optimize bend radii, segregation and EMC in cramped machines.

The rating reflects permissible thermal rise of 100 K at standstill with specified cooling for yielding 17.0 Nm at 13.6 A without exceeding winding limits. It sets baseline thermal loading for static holds, indexing and low-speed positioning.

The peak regions are intended for short duty cycles; ensure mechanical couplings, gearbox and drive current limits tolerate transients. It is important to validate thermal time constant and overload factors in the motor’s torque-speed curve before repeating peaks.
