Handling & installation

Before installation

Power on the robot only after it is securely fixed. Do not install or run a robot that is damaged or missing parts. Put a safety fence around the robot and clearly mark its motion area.

Unpacking check​

On delivery, check the contents against the packing list. When installing several robots, confirm the robot and controller serial numbers match; a mismatch can cause unexpected motion.

Handling​

  • The Marvin arms weigh 16–26 kg in total, including packaging and excluding the base. Lift them with several people; do not carry them alone.
  • The robot base weighs about 130 kg. Do not lift it by hand; use proper handling equipment.
  • Before long-distance transport, return the robot to its packing posture and use the dedicated carton.
  • Avoid excessive vibration and shock. Crane, forklift, and similar work must be done by qualified or authorized personnel.

Storage and environment​

Store at -10 to 60 °C without frost. The installation site must be:

  • Indoors, out of direct sunlight
  • Away from dust, oil mist, salt, metal chips, and flammable or corrosive liquids and gases
  • 0 to 45 °C during operation, 20 to 80 %RH (non-condensing)
  • Vibration at or below 4.9 m/s² (0.5 G)
  • Away from strong magnetic fields, electromagnetic sources (such as TIG welders), and electrical noise
  • Below 1000 m altitude

After a long stop near 0 °C, the drives may be stiff and raise an alarm at start-up. If so, warm up at 25% speed for 10 minutes.

Zero posture and zero calibration​

Before use, confirm the robot's zero posture matches Figure 2-1 of the manual. If it does not, contact Gento support.

Zero calibration is done at the factory and is not needed in daily use. Recalibrate after:

  • Replacing a joint driver or a whole joint
  • Reinstalling the system or replacing the controller drive
  • A severe collision

Calibration positions for each axis are in Figure 2-2 of the manual.

Fixing the arms​

Each arm base has 11 mounting holes. Recommended fasteners:

ItemRecommendation
ScrewHex socket head cap screw M4×14 (GB/T 3098.1-2010, grade 12.9)
WasherPlain conical spring washer (JIS B 1251-2018 2L-4)
Tightening torque4.8 N·m

  • The mounting surface must be flat to 0.05 mm or better; otherwise the base may be damaged or performance reduced.
  • Align the notch on the back of the robot base with the notch on the back of the mounting bracket.
  • The foundation must carry the static load and the reaction forces from arm motion.
  • With the arm fully extended, the wrist tool or workpiece must not touch walls or the fence.
  • Locating bolts, dowel pins, base plates, and other mounting parts are supplied by the customer.
  • The series can be mounted at any angle with the same fixing method. For wall or ceiling mounting, contact Gento first and add fall protection.
  • M3-SRS/CCS and M6-SRS/CCS share the same base and mounting method.

Base mounting dimensions for M6 and M3 are in Figures 2-3 and 2-4 of the manual.

Controller​

The controller main board sits in the controller box; its outline dimensions are in Figure 2-7 of the manual.
