6.4 Warning of cam operation
A warning is detected for an axis 1 when in the cam operation (cam data operation/cam auto-
generation/cam position calculation) is incorrect.
Warning of cam operation
(1) Warning detection
"b9: Axis warning detection of "[Md.31] Status" for axis 1 " turns ON, and the cam data
operation warning number/cam auto-generation warning number/cam position
calculation warning number is stored in "[Md.24] Axis warning No.".
(2) Resetting warnings
Remove the cause of warning following the actions described in Section 6.4.1, 6.4.2
and 6.4.3, before canceling a warning state through resetting the error of axis 1.
A warning state is canceled after the following processing is carried out by setting "1"
in "[Cd.5] Axis error reset" for axis 1.
• Axis error detection signal is turned OFF
• "[Md.23] Axis error No." is cleared
• "[Md.24] Axis warning No." is cleared
• Changing of "[Md.26] Axis operation status" from "Error" to "Standby".
• "Axis warning detection ([Md.31] Status: b9)" is turned OFF
POINT
A warning of cam operation occurs for an axis 1 without any condition. Judge
whether it was completed normally by confirming a warning state of axis after the
completion of cam operation.
