[2] Changing to a new current value using the current value changing
start No. (No. 9003)
In "current value changing" ("[Cd.3] Positioning start No." = 9003), "[Md.20] Feed
current value" is changed to the address set in "[Cd.9] New current value".
Operation chart
The current value is changed by setting the new current value in the current value
changing buffer memory "[Cd.9] New current value", setting "9003" in the "[Cd.3]
Positioning start No.", and turning ON the positioning start signal.

the current value changing buffer memory.
The above chart shows an example
when the positioning address is "0".
[Y10 to Y1F]
Restrictions
(1) The 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".
(2) The error "Software stroke limit +" (error code: 507) or "Software stroke limit -"
(error code: 508) will occur if the designated value is outside the software
stroke limit range.
(3) The current value cannot be changed during stop commands and while the M
code ON signal is ON.
(4) The M code output function is made invalid.
POINTS
The current value can be changed using the current value changing start No. (No. 9003), if "0:
Positioning control is not executed" is set in "[Pr.55] Operation setting for incompletion of HPR" and
HPR request flag is ON.
Current value changing procedure
