The VERO-S robot coupling for pallet handling is not being used as intended if, for example: • It is used as load handling or lifting equipment. • it is used for turning applications without consulting SCHUNK. • It is used as a quick-change pallet system for milling applications without consulting SCHUNK.
Basic safety notes 2.3 Notes on particular risks • Disconnect the power supply lines and ensure that there is no residual energy in the system before performing assembly, modification, maintenance, or adjustment work. • Do not move parts by hand when the energy supply is connected.
Page 9
Basic safety notes WARNING The system clamps using spring force. Risk of injury due to parts automatically moving to their end positions following actuation of an "emergency stop" or after switching off the power supply. Wait for the system to shut down completely. •...
If the robot coupling is to be operated in an environment with abrasive dusts or corrosive or caustic fumes or fluids, prior approval must be obtained from SCHUNK. Safety during assembly and servicing During assembly, connection, adjustment, commissioning and testing, make sure that no accidental operation of the robot coupling by the fitter or other persons is possible.
This is why only screws of strength class 12.9 may be used. Only original SCHUNK clamping pins may be used. If the clamping pin is to be used in customer-specific devices, the customer must provide a sufficiently dimensioned pallet coupling or a sufficiently thick mounting material.
Only allow specialists to remedy malfunctions. Spare parts Only use original SCHUNK spare parts. Environmental regulations The applicable environmental regulations must be observed for all maintenance and repair work.
Warranty 3 Warranty If the product is used as intended, the warranty is valid for 24 months from the ex-works delivery date under the following conditions: } 1.2 [ / 6] • Observe the applicable documents, • Observe the ambient conditions and operating conditions •...

Technical data 5.2 Calculation of Permissible Transport Load The robot coupling is limited to a maximum permissible torque at the coupling interface. The dynamic load when using the robot system for handling results in acceleration and deceleration forces that have to be taken into consideration for the transport load. To operate the robot coupling with dynamic handling, it is essential for the maximum acceleration of the machine to be known.
Page 17
Technical data Calculating the acceleration force: Maximum permissible torque for NSR3 138: M = 1500* Nm Result of calculation: Taking into account the robot acceleration, the loading weight obtained in the calculation example is permissible. * When using the PKL 138. If the PKL 160 is used, reduced load values apply (} 5.1 [ / 15]).
Assembly 6 Assembly Pre-assembly measures Carefully lift the product out of the packaging (e.g. with suitable lifting equipment).
