Page 4: Instructions On This Documentation
Instructions on this documentation This document only describes the utilisation of the safety function STO – “Safe Torque Off ” in accord ance with EN 61800-5-2, which is implemented in the controller CMXH, in combination with the related planar surface gantry EXCM-30/-40. -
Page 5: Safety And Requirements For Product Use
• Shut down the passive actuators mechanically if required, e.g. via a brake, to ensure that movements are prevented. This especially applies to vertical axes without auto matic locking mechanics, clamping units or counterbalancing. Festo – CMXH-STO-EN – 1612a – English... -
Page 6: Intended Use Of The Sto Function
EN 61800-5-2. The STO function is intended to shut down the torque from a motor that is connected to the CMXH, thereby preventing an unexpected restart of the motors. The STO function may only be used for applications in which the specified safety characteristics suffice. -
Page 7: Requirements For Product Use
• Keep the documentation safe throughout the entire product lifecycle. • Ensure compliance with all of the specifications in the documentation for the controller (è Tab. 1 Documentation for the system EXCM-30/-40 with CMXH). • Also take into consideration the documentation for the other components (e.g. motors, cables, etc.). -
Page 8: Function And Application
The safety function is requested solely via the control ports of the switch-off functions interface [X4] on the controller. Safety-oriented circuitry for additional interfaces of the controller is not required.

Page 13: Electrical Installation
The STO function must never be bridged. • Make sure that no jumpers etc. can be used parallel to the safety wiring, e.g. by using the maximum cable cross section of 0.5 mm Festo – CMXH-STO-EN – 1612a – English... -
Page 14: Notes On Commissioning
It is recommended that at least the STO function should be wired at initial start-up. The complete commissioning of the controller by the machine manufacturer is de scribed in the description EXCM-30/-40-...-PF and in the Online Help for the CMXH plug- in of the FCT software. -
Page 15: Diagnostics
The frequency of these tests must be determined by the machine operator based on the specifications of the machine manufacturer. An inspection of the controller is recommended at least once a year. Festo – CMXH-STO-EN – 1612a – English... -
