A system for controlling the operation of a motor being used for the rotational assembly or dis-assembly of two members, the system comprising means monitoring, and generating a digital or analogue signals representative of the state of the two members and means relaying the representative signal in a digital form to a first processor (6) means relaying the signal in an analogue form to a second processor (11); the first processor comprising a computer which in use, digitally analyses the representative signal and is so programmed as to generate a first control signal in response to the representative signal; the second processor comprising means converting the first control signal into analogue form and means comparing it with the analogue representative signal and generating second control signal representative of the difference between the first control signal and the representative signal; the second processor being so connected as to transmit the second control signal to the motor control means. |
