Tolerance requirements for the DC 24 V voltage supply

Three cases must be distinguished when planning the DC 24 V voltage supply.

  1. The BP and BK holding brake is controlled directly via the brake output of the axis module.
  2. The following servo brakemotors are connected or there is a mixed mode with the motors mentioned in case 2. The brake cable length is < 25 m:
    • CMP40/50/63/71, CMS/CMSB50 – 71, CM3C63
  3. The brake output is used as control output, e.g. brake control via a BMK, BME brake rectifier.
  4. No motor with a brake is connected.
