8. Wood-working machine adopting frequency inverter advantages:

Variable speed drives (VSDs) are sometimes referred to as converters, inverters, or variable frequency drives. They are designed to control the speed of a three-phase motor by varying both the voltage and frequency of the current. In addition to braking, motor speed control can also be used to: ■ reduce resonance of the tooling or workpiece; ■ reduce the need for changing speeds by belt changing etc to achieve an optimum cutting rate. When considering this method, the factors to take into account are: Starter type ■ A VSD will replace the existing motor starter. However, to ensure that the integrity of any emergency stop functions of a machine remain unchanged, it may be necessary to retain a motor contactor to ensure that the electrical supply can be switched off completely. This is because inverters are electronic devices and cannot be relied upon when switching the machine off for safety reasons, unless specifically designed for that purpose. However, it will be necessary to ensure that the contactor is operated only after the motor has stopped, otherwise the braking effects of the VSD will be lost. If using just an inverter drive it is even more important to isolate the machine correctly before undertaking any work on the rotating parts. Do not rely on the stop function alone. Safe electrical isolation is the most reliable way of preventing an unexpected start-up, provided that there are suitable means to ensure accidental reconnection is prevented – for example, breaking the 3-phase by mechanical means and a locking-off facility. ■ A VSD can allow the direction of rotation to be reversed. Where this is undesirable – such as on circular saws, where reversal can lead to loosening of the blade-retaining nut – it is important to select a VSD that can have reversing disabled.
