G.7 Automatic Parameter Updating Function
A-30
G.7 Automatic Parameter Updating Function
( 1 ) Parameters Updated when a MECHATROLINK Connection Is Established
(Machine Controller to Stepper)
When communication is in MECHATROLINK-II 32-byte mode and the User Constants Self-writing
Function bit (fixed parameter No. 1, bit 10) is set to 0 (enabled)
Only when using standard parameters.
( 2 ) Parameters Updated when a Setting Parameter is Changed
(Machine Controller to Stepper)
When communication is in MECHATROLINK-II 32-byte mode and the User Constants Self-writing
Function bit (fixed parameter No. 1, bit 10) is set to 0 (enabled)
The above parameters will also be automatically updated when Acceleration/Deceleration Degree Unit Selection bits
(OW
03, bits 4 to 7) is changed.
Only when using standard parameters
( 3 ) Parameters Updated When Execution of Motion Command Starts
(Machine Controller to Stepper)
In any communication mode when the User Constants Self-writing Function bit (fixed parameter No.
1, bit 10) is set to 0 (enabled)
Only when using standard parameters
In any communication mode, regardless of the setting of fixed parameter No. 1, bit 10
Only when using standard parameters
