摘要： PURPOSE:To attain positioning with high accuracy by providing the revolving angle detectors to both output and input shafts of a reduction gear and detecting an error of rotational frequency between both shafts to correct the drive command value. CONSTITUTION:A reduction gear 1 combines many gears and reduces the revolution of an input shaft 1a down to 1/n to transmit it to an output shaft 1b. While angle detectors 2 and 3 are connected to both shafts 1a and 1b respectively and output detection pulses EP and TP for each revolution by a fixed angle. A control part 7 is driven by a motor 4 and the shaft 1a is revolved. When the gear 1 has the backlash, etc., a difference of rotational frequency is produced between both shafts 1a and 1b. Therefore the count values of both counters 5 and 6 are monitored by the part 7, and an error is obtained between both count values. Then the part 7 corrects said error with the drive command value DS and gives revolutions to the shaft 1a in an extra amount equivalent to said error. This corrects an error due to the backlash, etc. of the shaft 1b and attains the accurate positioning.
摘要翻译：目的：通过向减速齿轮的输出轴和输入轴提供旋转角度检测器，并检测两轴之间的转速误差，以更正驱动指令值，以高精度实现定位。构成：减速齿轮1结合了许多齿轮并将输入轴1a的转速降低到1 / n，以将其传送到输出轴1b。而角度检测器2和3分别连接到两个轴1a和1b，并且每转一次输出检测脉冲EP和TP一个固定的角度。控制部7由电动机4驱动，轴1a旋转。当齿轮1具有齿隙等时，两轴1a和1b之间产生旋转频率差。因此，计数器5和6的计数值由部件7监视，并且在两个计数值之间都获得错误。然后，部件7用驱动指令值DS校正所述误差，并以相当于所述误差的额外量给予轴1a的转数。这样可以纠正由于轴1b的齿隙等导致的误差，并达到准确的定位。

摘要： PURPOSE:To measure an accurate back lash by operating a power transmission mechanism by the same driving source as that in a use state, and detecting the rotational quantitits of the input and output shafts of the transmission mechanism from the output of a detector. CONSTITUTION:A control part 7 drives a motor 4 forward with a drive signal DS to rotate the input shaft 1a of a speed reduction gear 1. This rotation turns the output shaft 1b. A back lash, on the other hand, is caused when the speed reduction gear 1 reverses, so the rotation of the input shaft 1a is stopped after the motor 1 turns forward, and then the motor 1 is reversed to turn the input shaft 1a backward and then stop it. Detection pulses EP and TP detected in those forward and backward turns are counted up (forward rotation) and down (backward rotation) by counters 5 and 6, and a control part 7 obtains the rotational quantities from the values of both counters 5 and 6 after the reverse turn, thereby calculating the back lash from an arithmetic expression.

摘要： PURPOSE:To attain positioning with high accuracy by providing angle detectors to both input and output shafts of a reduction gear and detecting the revolving angle of the input shaft while the output shaft has no revolution to correct the command value. CONSTITUTION:A reduction gear 1 consists of a gear mechanism and reduces the revolution of an input shaft 1a down to 1/n to transmit it to an output shaft 1b. Angle detectors 2 and 3 are provided to both shafts, and a motor 4 is driven by a differential circuit 7 which obtains the differentials between the present position of a counter 6 and the position commands of a control part 5 and the counter 6 and delivers a drive command. Thus the shaft 1a is revolved. Then the start of revolution of the shaft 1b is monitored from the start of the reversal with the output of the detector 3 of the shaft 1b. The rotational frequency of the shaft 1a is obtained by the count value of the counter 6 during said monitoring. Thus the backlash of conversion of the shaft 1a is detected and the motor 4 is driven for correction of the shaft 1a by an amount equivalent to said backlash.
