Unit of competency
Modification History
Release 1. This is the first release of this unit of competency in the UEE Electrotechnology Training Package. |
Application
This unit involves the skills and knowledge required to diagnose and rectify faults in system controlling servo drive systems. It includes applying safe working practices; interpreting technical data; applying knowledge of servo/stepper drives operating parameters to logical fault-finding processes; implementing fault rectification, safety and functional testing; and reporting work activities and outcomes. The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 volt (V) alternating current (a.c.) or 120 V direct current (d.c.). Competency development activities in this unit are subject to regulations directly related to licensing. Where a licence or permit to practice is not held, skills and knowledge described in this unit require a relevant contract of training, such as an Australian Apprenticeship. Additional and/or other conditions may apply in some jurisdictions subject to regulations related to electrical work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations. Permits may also be required for some work environments, such as confined spaces, working aloft, near live electrical apparatus and site rehabilitation. No other licensing, legislative or certification requirements apply to this unit at the time of publication. |
