Identify the brake and motor roles

Obtain the exact machine-state and brake documentation. Kollmorgen's holding-brake example uses an energized coil to release a brake and distinguishes holding from dynamic stopping. That arrangement and behavior must not be assumed for every machine. A brake on a component list is not proof that the machine is designed to remain secured after all supplies disappear.

Map power in each accepted state

Record motor holding, brake release, controls and any retained auxiliaries during ready, motion and approved parked states. The axis can change which electrical demand is present without changing its visible position. Include the timing and actual feedback requirements through the machine designer. This page provides no brake-release sequence, holding test or permission to disable a safety-related function.

Record the accepted holding state with its required feedback. A coil being de-energized or an axis remaining still for one observation does not alone demonstrate that the documented retention function has been achieved.

Keep renewable control outside unapproved transitions

An energy-saving request should use only a machine-supported state that the responsible owner accepts. Do not infer that cutting a coil supply is a suitable way to park an axis or manage wind variation. Give the integrator the accepted combined input and required response to source interruption. Wind energy contribution can be assessed separately from load retention. The supplier enquiry should identify who approves those machine functions; neither a turbine rating nor a general brake manual establishes a MARSTON axis-control interface or safe holding capability.
