12 DATA USED FOR POSITIONING CONTROL
12.7 Monitor Data
[Md.22] Feedrate
This area stores the command output speed of the operating workpiece. The stored value may be different from the actual
motor speed during operation. Multiplying the stored value by the following converted value enables the monitoring of the
converted value in each unit.
• During interpolation operation, the composite speed or reference axis speed is stored for the reference axis and 0 is stored
for the interpolation axis.
• The update cycle of this area is 0.88ms.
■
Buffer memory address
The following table shows the buffer memory address of this area.
[Md.23] Axis error No.
When an error is detected, this area stores the error code corresponding to the error. Monitor the value in hexadecimal.
• The latest error code is stored at all times and when a new error occurs, the error code is overwritten.
• When [Cd.5] Axis error reset (axis control data) is turned on, the error code is cleared to 0.
■
Buffer memory address
The following table shows the buffer memory address of this area.
[Md.24] Axis warning No.
When a warning is detected, this area stores the warning code corresponding to the warning. Monitor the value in
hexadecimal.
• The latest warning code is stored at all times and when a new warning occurs, the warning code is overwritten.
• When [Cd.5] Axis error reset (axis control data) is turned on, the warning code is cleared to 0.
■
Buffer memory address
The following table shows the buffer memory address of this area.
[Md.25] Valid M code
This area stores the M code that is currently valid (i.e. set to the positioning data relating to the current operation).
• The range of the stored value is 0 to 65535.
• This area is updated when M code ON signal [X4, X5, X6, X7] turns on.
• When PLC READY signal [Y0] is turned off, 0 is stored.
