Stored Stroke Limit - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

Stored stroke limit

Software limit -/Software limit +
Set the movement range in the + direction (upper limit value) and - direction (lower limit value) of the stored stroke limit.
In the following cases, a moderate error (error code: 30FDH (details code: 0024H)) occurs.
Rotation axis
0: Linear axis
1: Rotation axis
The following types of stored stroke limit are available.
■Stored stroke limit I
Going outside of the set perimeter is prohibited.
The stroke limit is not valid immediately after turning ON the power supply of controlling equipment. Instead, it becomes valid
after transition to G-code control. During G-code control, the fixed parameter stroke limit settings become invalid. When
transitioning to G-code control, if there is an axis outside of the valid range for machine movement, there is no transition to G-
code control, and a minor error (error code: 1FC1H (details code: 0101H)) occurs.

In automatic operation, a minor error (error code: 1FC2H (details code: 0221H)) occurs to avoid going into the prohibited area.
When an error occurs on one axis, all axes decelerate to a stop. The stopping position is always before the prohibited area.
The distance (L) between the prohibited area and stop position differs according to the feed speed.
Before transition to G-code control, check that there are no problems with the current machine position using
"[Md.20] Feed current value (R: D32000+48n, D32001+48n/Q: D0+20n, D1+20n)". When the axis unit setting
is [degree], "[Md.20] Feed current value (R: D32000+48n, D32001+48n/Q: D0+20n, D1+20n)" is the rotating
range (0 to 359.99999[degree]), but to check the machine position in the linear range (-2147483648 to
2147483647), set the "cumulative current value" data type in the optional data monitor setting. It can then be
checked in the set storage device.
