(c) Positioning data setting example
The following table shows the setting examples when " current value changing" is set in the positioning data
No. 1 of axis 1.
Refer to  Page 152, Section 5.3 for information on the setting details.
(2) Changing to a new current value using the start No. (No. 9003) for a current
value changing
(a) Operation chart
The current value is changed by setting the new current value in the current value changing buffer memory
"[Cd.9] Current value changing", setting "9003" in the "[Cd.3] Positioning start No.", and turning ON the
positioning start signal.
(b) Restrictions
• The axis error "Outside new current value range" (error code: 514) will occur if the designated value is
outside the setting range when "degree" is set in "Unit setting".
• The error "Software stroke limit +" or "Software stroke limit -" (error code: 507 or 508) will occur if the
designated value is outside the software stroke limit range.
• The current value cannot be changed during stop commands and while the M code ON signal is ON.
• The M code output function is made invalid.
