1 START AND STOP
1.2 Stop
*1 If an error occurs in a positioning data due to an invalid setting value, when the continuous positioning control uses multiple positioning
data successively, it automatically decelerates at the previous positioning data. It does not stop suddenly even the setting value is
sudden stop in stop group 3. If any of the following error occurs, the operation is performed up to the positioning data immediately before
the positioning data where an error occurred, and then stops immediately.
No command speed (error code: 1A13H, 1A14H)
Outside linear movement amount range (error code: 1A15H, 1A16H)
Large arc error deviation (error code: 1A17H)
Software stroke limit + (error code: 1A18H, 1A19H)
Software stroke limit - (error code: 1A1AH, 1A1BH)
Sub point setting error (error code: 1A27H, 1A28H, 1A29H, 1A2AH, 1A37H)
End point setting error (error code: 1A2BH, 1A2CH)
Center point setting error (error code: 1A2DH, 1A2EH, 1A2FH)
Outside radius range (error code: 1A32H)
Illegal setting of ABS direction in unit of degree (error code: 19A4H, 19A5H)
