Page 5: Safety
Please read the information included in cautions and warnings carefully. ® VACON 20 X is a drive conceived for controlling asynchronous AC motors and permanent magnet motors. The product is inteded to be installed in a restricted access location and for a general purpose use. -
Page 6: Warnings
Only DVC A circuits (Decisive Voltage Class A, according to IEC 61800-5-1) are allowed to be connected to the control unit. This hint aims to protect both the drive and the client-application. Vacon is not responsible for direct or consequen- tial damages resulting from unsafe connections of external circuits to the drive. -
Page 7: Earthing And Earth Fault Protection
CAUTION! ® The VACON 20 X AC drive must always be earthed with an earthing conductor connected to the earthing terminal marked with Since the touch current exceeds 3.5 mA AC, according to EN61800-5-1, the drive shall have a fixed connection and provision of an additional terminal for a second protective earthing con- ductor of the same cross-sectional area as the original protective earthing conductor. - Page 8 ® In VACON 20 X, the phase conductor and the corresponding protective earthing conductor can be of the same cross-sectional area, provided they are made of the same metal (because the cross-sectional area of the phase conductor is less than 16 mm...

Page 11: Compatibility With Rcds
Safety vacon • 8 Compatibility with RCDs This product can cause a d.c. current in the protective earthing conductor. Where a residual current-operated protective (RCD) or monitoring (RCM) device is used for protection in case of direct or indirect contact, only an RCD or RCM of Type B is allowed on the supply side of this product. -
Page 12: Extended Temperature Range
® VACON 20 X has an integrated cooling system, independent from the motor fan. Under max- imum operating conditions, the ambient temperature cannot exceed 40 °C. See Table 19 for the output rated current. Higher temperatures are allowed only with derating of the output current. -

Page 72: Standards
• 69 Safe Torque Off Standards The STO function has been designed for being used in accordance with the following standards: Standards IEC 61508, Parts 1-7 EN 61800-5-2 EN 62061 ISO 13849-1 EN 954-1 IEC 60204-1 Table 29. Safety Standards. -
Page 73: The Principle Of Sto
® In VACON 20 X, the STO function is realized by preventing the propagation of the control signals to the inverter circuit. The inverter power stage is disabled through redundant disabling paths which start from the two separated and galvanically isolated STO inputs (S1-G1, S2-G2 in Figure 36). -
Page 74: Technical Details
The reaction time of the STO function is the amount of time which passes from the moment in which ® the STO is demanded till the system is in the Safe State. For VACON 20 X, the reaction time is 20 ms minimum. -
Page 75: Connections
Safe Torque Off vacon • 72 Connections To make the STO function available and ready to be used, both the STO jumpers have to be removed. They have been located in front of the STO terminal to mechanically prevent the insertion of the STO inputs. -
Page 76: Safety Capability Cat.4 / Pl E / Sil 3
• 73 Safe Torque Off Safety Capability Cat.4 / PL e / SIL 3 9.5.1 For this safety capability, an external safety device must be installed. This must be used to dinami- cally activate the STO inputs and to monitor the STO output feedback. - Page 77 Safe Torque Off vacon • 74 The picture below shows an example of connection for the STO function. The external device has to be connected with 6 wires to the drive. EXTERNAL DEVICE POWER UNIT DC+/R+ DC-* Reinforced Figure 39.

• 75 Safe Torque Off Safety Capability Cat. 3 / PL e / SIL 3 9.5.2 The safety capability is reduced to Cat. 3 / PL e / SIL 3 if the STO inputs are statically used(which means they are forced to commute together). -

Safe Torque Off vacon • 76 Safety Capability Cat.1 / PL c / SIL 1 9.5.4 Without any automatic monitoring of STO output feedback, the safety capability is reduced to Cat. 1 / PL c / SIL 1. The STO inputs (which can be connected in parallel) must be supplied by a safety push button or a safety relay. -
Page 80: Commissioning
• 77 Safe Torque Off Commissioning 9.6.1 General wiring instructions Protect the STO cabling with a shielding or an enclosure to exclude external fault. Wires ferrules are highly recommended for all STO signals (inputs and feedback). The wiring should be done according to the general wiring instructions for the specific product. A shielded cable is required. -
Page 81: Parameters And Fault Tracing
Safe Torque Off vacon • 78 Parameters and fault tracing There are no parameters for the STO function itself. Before testing the STO function, make sure that the checklist (Table 36) is inspected and completed. When STO function awakes, the drive always generates a fault (“F30”) and the motor stops by coasting. -
