NSK EDD Megatorque Motor - User Scale Positioning

8. More Advanced Function
— 8-36 —
8.6.4. User Scale Positioning
 The dividing number of entire circumference of Motor rotation can be set to the unit of positioning
command. Thus, the following positioning can be easily performed.
 An index positioning in units of 90 angle degree (dividing number = 4)
 A positioning in units of 1/1000 angle degree (dividing number = 360 000)
 A positioning in units of the same circumference resolution of other Motor
 The parameter QR (Dividing number, user scale) specifies the dividing number of total circumference.
 The commands AQ and IQ (Positioning command, user scale) execute a positioning whose dividing
number is specified by the parameter QR.
 Use the monitor TQ (Tell current position, QR unit) to read out the current position in units of dividing
number.
