Frequently Asked Questions
What is the function of the 32 Nm electrically-released holding brake on MSK100A-0450-NN-M1-BP1-NNNN?
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.
How does the 7,800 mH winding inductivity of MSK100A-0450-NN-M1-BP1-NNNN affect current-loop design?
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.
What does “B-side power connector” on MSK100A-0450-NN-M1-BP1-NNNN imply for cable management?
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.
How should I interpret “continuous torque at standstill (100 K) 17.0 Nm at 13.6 A” on MSK100A-0450-NN-M1-BP1-NNNN?
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.
When can the 54.0 Nm / 54.0 A peak capability of MSK100A-0450-NN-M1-BP1-NNNN be used safely?
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.
