5 DATA USED FOR POSITIONING CONTROL
Storage item Storage details
Md.42 Target speed
During operation with positioning data : The actual target speed, considering
the override and speed limit value,
etc., is stored. "0" is stored when
positioning is completed.
During interpolation : The composite speed or reference
axis speed is stored in the reference
axis address, and "0" is stored in the
interpolation axis address.
During JOG operation : The actual target speed, considering
the JOG speed limit value for the
JOG speed, is stored.
During manual pulse generator operation : "0" is stored.
Md.43 Zero point absolute position
The "zero point absolute position" address is stored.
"0" is stored when the power is turned ON, and the zero point return basic
parameter "
Pr.47
Zero point address" is stored when the machine zero point
return is completed.
The zero point absolute position value is changed when the current value change
function is executed.
Md.44 Movement amount after
near-point dog ON
"0" is stored when machine zero point return starts.
After machine zero point return starts, the movement amount from the near-point
dog ON to the machine zero point return completion is stored.
(Movement amount: Movement amount to machine zero point return completion
using near-point dog ON as "0".)
"0" is always stored when not using the near-point dog, or when using the
stopper stop method.
Md.45 Torque limit stored value
The "
Pr.18
Torque limit setting value" or "
Cd.30
New torque value" is stored.
During positioning start, JOG operation start, manual pulse generator operation
...The "
Pr.18
Torque limit setting value" is stored.
When value is changed to "
Cd.30
New torque value" during operation
...The "
Cd.30
New torque value" is stored.
