Control using CHGA-E instruction
(1) Executing the CHGA-E instruction changes the current value of the synchronous
encoder shaft in the following procedure.
(a) The synchronous encoder shaft current value changing flag (M2101 to
M2112) corresponding to the specified synchronous encoder shaft is turned
on.
(b) The current value of the specified synchronous encoder shaft is changed to
the specified address.
(c) The synchronous encoder shaft current value changing flag is turned off at
completion of the current value change.
(2) The used axis No. can be set within the following range.
Q173DSCPU
(3) The address which made the current value change by CHGA-E instruction is
valid after also the power supply turned off.
