IPC: B23Q17/00
Filed: 1984-06-18
Abstract: PURPOSE:To make delicate spindle control performable in a speedy and accurate manner, by securing a various-state signal of a spindle with a simple circuit structure using a arithmetic unit and its peripheral devices. CONSTITUTION:Since a speed arrival signal of a various-state signal for spindle control becomes higher in its actual speed in proportion as a command speed becomes higher, a difference between both rates is compared with an absolute value ASER of the deviation calculated, and when the VADL is larger it is set, outputting it from an output port 2. Next, a speed stop signal compares an absolute value of the read actual rate with a speed zero level, and when it is below the zero level, a timer is set and when continuing to 12ms, it is set to a register of the port 2, while a speed detection signal compares such a signal as being detected as the speed zero with a speed detection level, and when it is above the detection level, a speed detection port of the port 2 is set. Next, a deviation undue signal is outputted when a spindle stops more than the setting value, whereas the absolute value ASER is more than the setting value during constant rotation of the spindle and speed command voltage is a command below the setting value, and it is set down to a deviation undue alarm.
