摘要： Time information t and positional information about each axis are obtained, and the three-dimensional coordinates of tool center point Pe at time t are calculated to display the path of the tool center point Pe at time t. Then, whether a fixed time has elapsed or not is decided. If the fixed time has elapsed, the coordinates of the tool vector start point Ps at time t are calculated to display a line segment connecting between tool vector start point Ps and tool center point Pe, which is the end point of the tool vector. This display enables the orientation of the tool at each tool center point to be grasped at a glance.

摘要： A motor control apparatus that can calculate a proper amount of cogging torque compensation even in cases where components due to other factors than cogging torque (for example, components due to gravitational torque, etc.) are superimposed on a torque command being output during constant slow-speed feed operation. The motor control apparatus includes: a torque command monitoring unit which monitors a torque command when the motor is caused to operate at a constant speed; an approximation calculation unit which calculates a torque command approximation component by approximation from the torque command monitored over an interval equal to an integral multiple of the cogging torque period of the motor; a second torque command calculation unit which calculates a second torque command by subtracting the torque command approximation component from the torque command; a second torque command frequency analyzing unit which extracts frequency components, each at an integral multiple of the fundamental frequency of the cogging torque, by performing frequency analysis on the thus calculated second torque command; and a cogging compensation amount calculation unit which calculates the amount of cogging compensation from the amplitude and phase of the extracted frequency components.

摘要： A controller of an industrial machine provided with an electric motor, a peripheral apparatus and an amplifier includes a motor power-consumption calculation section, a power loss calculation section, a fixed power-consumption calculation section, and a total power-consumption calculation section. The motor power-consumption calculation section calculates motor power consumption by decomposing a motor current into a Q-phase current value and a D-phase current value, and multiplying the Q-phase current value with a motor rotation speed and a motor torque constant. The power loss calculation section calculates sum power loss of the motor and amplifier. The fixed power-consumption calculation section calculates fixed power consumption of the peripheral apparatus. The total power-consumption calculation section determines total power consumption of the industrial machine in a predetermined time period by integrating, for the time period, the calculated motor power consumption, sum power loss and fixed power consumption.
