Project Planning Manual | Rexroth MKE Synchronous Motors Electric Drivesand Controls| Bosch Rexroth AG 91/131Operating Conditions and Application NotesDANGERPersonal injury through hazardous movements caused by falling or descendingaxes!Secure vertical axes against falling or descending after disconnection:●●●lock the vertical axes mechanically,provide an external braking / collecting / clamping device, orensure sufficient equilibration of the vertical axes.The serially delivered holding brakes which are driven by the control device arenot suited for personal safety!Ensure protection of persons by superordinate fail-safe measures.Cordon off the hazardous area by means of a safety fence or a safety screen.Observe supplementary standards and recommendations.For European countries:● EN 954 and ISO 13849-1 (2003) and ISO 13849-2 (2007)Safety-related components of controls●For US:●"Vertikalachsen" Leaflet on vertical axes (Editor: SüddeutscheMetall - Berufsgenossenschaft Fachausschuss Eisen undMetall II, Wilhelm–Theodor–Römheld-Str.15, 55130 Mainz,Germany)See National Electric Code (NEC), National Electrical ManufacturersAssociation (NEMA) as well as local building regulations.The following is generally valid: Comply with all applicable nationalregulations!The permanent magnetic brake is no safety brake. This means, a torque reductionby non-influenceable disturbance factors can occur (see EN 954 andISO 13849-1 (2003) and ISO 13849-2 (2007) or the leaflet about vertical axesSMBG).Please pay particular attention to the following:●●●Corrosion on friction surfaces, as well as dust, perspiration and sedimentsreduce the braking effect.Grease must not hit the friction surface.Over voltage and too high temperatures can weaken the permanent magnetsand therewith the brake.Engaging of the brake is no longer ensured, if the air gap between armatureand pole is improperly increased due to deterioration. In this case, no brakingoccurs.9.11.3 Holding Brakes Note Regarding the System's SafetyControl of the holding brake duringoperation (recommendation)Malfunctions that occur in the course of the operating period and that maychange the design parameters or the operating conditions, must be recognisedand eliminated within an appropriated period of time. For this case, we recommendto check the function and the state of the holding brake in regular timeintervals (see chapter 9.11.5 "Holding Brake–Commissioning and MaintenanceInstructions" on page 92).
