  • Page 22: Introduction Of Modules

    Mounting Introduction of modules The mechanical concept of Vacon 100 X drive is based on two segregated parts, power and con- trol, connected to each other by pluggable terminals. The power unit, called powerhead, in- cludes all the power electronics such as the EMC-filter, IGBTs, capacitors, choke or power boards while the control board and the control terminals are located in the terminal box.

  • Page 23: Mounting

    Mounting vacon • 20 Mounting The drive consists of two main elements: 1. The terminal box that includes the power terminals and control board with the control ter- minals and 2. The powerhead containing all the power electronics. To install the drive, both parts need to be separated. The terminal box must be fixed first and all cabling done.

  • Page 24: Wall-Mounting

    The drive can also be mounted on a motor (on top or on any side of the motor). The drive is equipped with a cooling system independent of the motor. Motor-mounting requires special adapting components. Contact your local Vacon distributor for additional information. 3.3.3...

    • 91 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 • 92 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.

    • 93 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.

    Safe Torque Off vacon • 94 Parameters and fault tracing There are no parameters for the STO function itself. Before testing the STO function, make sure that the checklist (Table 33) is inspected and completed. When STO function awakes, the drive always generates a fault (“F30”) and the motor stops by coasting.
