Abstract
A motor driving control apparatus having a function for performing an individual test operation of a servomotor driving control apparatus or an inverter apparatus by generating test operation command in the control apparatus in place of a command from an external controller, whereby both a function check and a performance check can be performed to attain an improvement in reliability and case of operation.
Claims21
A motor driving control apparatus for driving a motor according to a control command from an external apparatus, in which said motor driving control apparatus comprises:
- test operation control command generation means for generating a control command having a predetermined pattern for driving said motor in a test operation;
- control command selection means for selecting one of the control command from said external apparatus and the control command from said test operation control command generation means as a control command for said motor;
- and
- operation analysis means for analyzing an operation of said motor in accordance with the control command from said test operation control command generation means, thereby providing said motor driving control apparatus with a self-diagnosis function.
A motor driving control apparatus for driving a motor according to a control command from an external apparatus and for performing feedback control for at least one of a rotational position and a rotational speed of said motor, in which said motor driving control apparatus comprises:
- test operation control command generation means for generating a control command having a predetermined pattern for driving said motor in a test operation;
- control command selection means for selecting one of the control command from said external apparatus and the control command from said test operation control command generation means as a control command for said motor;
- and
- operation analysis means for analyzing an operation of said motor in accordance with the control command from said test operation control command generation means, thereby providing said motor driving control apparatus with a self-diagnosis function.
A method of operating a motor driving control apparatus having test operation control command generation means for generating a control command having a predetermined pattern for driving a motor in a test operation, which comprises the steps of:
- determining whether the motor driving control apparatus is to be operated in an external control command operation mode or a test operation mode;
- operating the motor driving control apparatus according to the control command from the test operation control command generation means to drive the motor in the test operation when the motor driving control apparatus is to be operated in the test operation mode;
- and
- ascertaining whether an operation of the motor in the test operation is in accordance with said control command having a predetermined pattern.
A motor driving control apparatus for driving a motor according to a control command from an external apparatus, in which said motor driving control apparatus comprises a micro-controller section, a power amplifier section, and a change-over commander section, said micro-controller section including:
- test operation control command generation means for generating a control command having a predetermined pattern for driving said motor in a test operation;
- control command selection means for selecting one of the control command from said external apparatus and the control command from said test operation control command generation means, based on a command signal from said change-over commander section, as a control command for said motor;
- an automatic position control portion;
- an automatic speed control portion;
- an automatic current control portion;
- and
- operation analysis means for analyzing an operation of said motor in accordance with the control command from said test operation control command generation means.
