Gas springs have the advantage of being lighter and requiring less replacement time than coil springs, but as they are devices that use high-pressure gas, natural leaks occur. Periodic inspection by the user is required to manage this.

Application ModelHS180/220, HH300,HS200L
Replacement M/H0.5 hours (depending on environment)
integrityPeriodic inspection. Twice a year (refer to manual)
caution
  • Problem that occurs when gas spring pressure drops: H-axis overload error occurs (robot stops)
    • Depends on the level of leakage. Depending on the load on the H axis, it may not occur even if the entire amount of leakage occurs.
    • Overcurrent warning occurs (H-axis warning needs to be checked)

How to check pressure​

  • Apply pressure automatic detection function (Hi5a version MV40.17.00 or higher)

    • Warning occurs below 60 bar
    • Error occurs below 30 bar (robot stops)
    • Warning level can be manually set in T/P (details announced later)

  • Manual measurement using a pressure gauge (general pressure gauge: digital (PT118) recommended)

How to respond when pressure drops​

  • Problems when using gas springs while neglecting natural pressure drop
    • The friction angle between the cartridge and the tube increases, causing damage to the seal.
    • Early damage to gas springs occurs

Check whether the robot body and the controller number are the sam​

caution

If there are multiple robots, be careful of mixing the main body and controller!

Select robot program (JOB file: No. 9999) and move​

  • Select program (press Shift key + Program-Step key simultaneously), enter 9999 and press ENTER
  • Select step number (Press Program-Step key / 1 input ENTER)
  • Robot operation: Motor ON - Deadman switch ON - Step forward (FDW) and move to step 1
  • After moving, the data should be the left posture below and each axis data on the right.

The encoder recorded value attached to the control panel and the left corrected encoder value of the TP encoder offset must be the same​

(System – Robot Parameters – Encoder Options Screen)

Check whether the scale of each axis of the robot body matches​

Please refer to the notice regarding maintenance precautions for the gas spring applied to the models supplied by our company.

target model​

  • HS220 series : HS220, HS180, HS160L, HS210E
  • HH300 series : HH300, HS200L, HS260

Management method​

Gas springs were adopted because they have the advantage of being lighter and easier to replace than coil springs, but as they are devices that use high-pressure gas, natural leaks may occur, so periodic inspection and replacement by the user is required. (Reference: Main unit manual 4-2)

Inspection is performed every 6 months, and gas charging or replacement is required if the pressure drops. (Reference for details: Chapter 9 of the main unit manual).

If leakage is left unattended, it may cause damage to the gas spring and drive system (motor/reducer). (Caution: If the pressure of the gas spring is lowered, depending on the load, there is a risk of the axis falling when the servo is turned off in the maximum radius position.)

What to do under pressure​

  1. Above 100 bar: No or little leakage. Maintain or charge to 140 bar.
  2. Below 100 bar:
  • When gas charging is possible: If the pressure is maintained after charging, use it. If there is a rapid leak after charging, request gas spring replacement or repair. The lifespan of the gas spring is 3 to 4 years (20,000 hours), and periodic repair/replacement is recommended.
  • If there is no charger: Contact Hyundai Robotics A/S. (Gas charging and exchange)

Apply monitoring software​

  • Provides a function to monitor the pressure of the gas spring for efficient management. (Applies to MV40.11 or higher, recommended MV40.17 or higher)
