(2) Positioning control
*1 When multiple positioning data is executed by the continuous positioning control and there is invalid setting value in a
positioning data, an error occurs and deceleration is performed at the previous positioning data. In this case, sudden
stop is not performed even when it is set for the stop group 3. If any of the following error occurs, the operation is
immediately stopped after executing up to previous positioning data of the positioning data where an error occurred.
• No command speed (error code: 503)
• Outside linear movement amount range (error code: 504)
• Large arc error deviation (error code: 506)
• Software stroke limit + (error code: 507)
• Software stroke limit - (error code: 508)
• Sub point setting error (error code: 525)
• End point setting error (error code: 526)
• Center point setting error (error code: 527)
• Outside radius range (error code: 544)
• Illegal setting of ABS direction in unit of degree (error code: 546)
