<strong>Project</strong> <strong>Planning</strong> <strong>Manual</strong> | <strong>Rexroth</strong> <strong>MKE</strong> Synchronous Motors Electric Drivesand Controls| <strong>Bosch</strong> <strong>Rexroth</strong> AG 93/131Operating Conditions and Application Notes●If the specified holding torque (M4) is not attained after several grinding-inprocesses, the holding brake is not operable. Please consult<strong>Rexroth</strong> Service.During operationA missing holding torque of holding brakes caused by tear and corrosion canlead to operational disturbances in machines and plants. For this case,IndraDrive control devices offer the advantage to control the efficiency of theholding brake at regular intervals. This brake test can be carried out e.g. in theframework of a preventive maintenance (see P-0-0541, C2100 Command holdingsystem check).In order to counteract to an unsufficient holding torque, there is also the possibilityto grind in the holding brakes:1. Realisation of the grinding-in routine IndraDrive "Reconstition of the holdingtorque" (see P-0-0544, C3900 Command grind in motor holdingbrake). A repeated realisation of the grinding-in routine is possible.2. Grinding-in routine due to superior control. Here, special control programsadapted to the machine and system concepts are required. If necessary,please contact your <strong>Bosch</strong> <strong>Rexroth</strong> distribution partner and discuss thegrinding-in parameters for your application.9.12 Acceptances and Authorizations9.12.1 Motors in EU VersionDeclaration of conformityCE symbolCertificate of conformity certifying the structure of and the compliance with theapplicable EN standards are available for all <strong>MKE</strong> motors.
