Study notes

  • Hollow wrist with internally routed cables reduces external cable interference and cable damage risk.
  • Maximum static load torque for MZ35S: J4 110 Nm, J5 110 Nm, J6 60 Nm.
  • Maximum moment of inertia for MZ35S: J4 5.0 kgm², J5 5.0 kgm², J6 1.5 kgm².
  • Application cables: 24 wires, including wires for optional valves.
  • Cleanliness: ISO Class 4 equivalent; noise level: 75 dB.
  • Position repeatability is JIS B 8432 compliant.
  • J1 can be ordered with an optional ±180° range.
  • Control units FD20 and FD18 are named; no matching controller id is available.
  • Applications listed: machine tending, material handling, palletizing, dispensing.
  • Installation method lists floor, inverted, and angle; additional information also lists cleanroom, tabletop, and invert/ceiling mount.
  • Maximum speed values are maximums and vary with work program and wrist load conditions.

Safety

  • Wrist protection is IP67 equivalent; wire-harness section is IP65 equivalent; FD20 and FD18 control units are IP54 equivalent.
  • Option OP-P6-016/-017 (J2-axis encoder connector protector) reduces the rating from IP67 equivalent to IP54 equivalent.
  • Do not use liquids that degrade seal components, such as organic solvents, acids, alkalis, chlorinated compounds, or gasoline-based cutting fluids.
  • Ambient humidity: 20–85%RH, with no dew or frost allowed; vibration: not more than 0.5G (4.9 m/s²).
  • Altitude: up to 1000 m from sea level; ambient temperature must be reduced above the allowable altitude.
  • Control unit ambient temperature rating: 0–40°C.
  • Cleanroom use requires downward air flow and removal of dust/particulates plus wipe-down cleaning; the robot is not shipped in dust-proof packaging.
  • Explosion-proof version is not available.
