function
This function holds the current value.
This function sets the absolute position coordinate in relation to the OP in the
machine movement range, and prevent the OP from being lost even if the
power supply is turned OFF to ON.
This function temporarily stops the operation to confirm the positioning
operation during debugging, etc.
The operation can be stopped at each "automatic deceleration" or
"positioning data".
This function stops the positioning being executed (decelerates to a stop)
when the skip signal is input, and carries out the next positioning.
This function issues a sub work (clamp or drill stop, tool change, etc.)
according to the code No. (0 to 65535) set for each positioning data.
This function stores the address positioned with manual control into the
positioning address (
Da.6
the designated positioning data No.
This function changes the target position during the execution of positioning.
At the same time, this also can change the speed.
At each automatic deceleration, this function calculates the remaining
distance for the QD75MH to reach the positioning stop position, and when
the value is less than the set value, sets the "command in-position flag".
When using another sub work before ending the control, use this function as
a trigger for the sub work.
This function adjusts the control acceleration/deceleration.
This function shortens the virtual start time.
Function that turns ON the flag when the constant speed status or
acceleration status switches to the deceleration status during position
control, whose operation pattern is "Positioning complete", to make the
stop timing known.
Function that selects a deceleration curve when a stop cause occurs
during deceleration stop processing to speed 0.
This function is executed the positioning control by the 10 x speed of the
command speed and the speed limit value when the setting unit is "degree".
This function is provided to select whether positioning control is operated or
not, when OPR request flag is ON.
