[Md.22] Feedrate
The command output speed of the operating workpiece is stored. (May be different from the actual motor speed during
operation)
As shown in the diagram below, the hexadecimal monitor value is changed to a decimal integer value. The decimal integer
value can be converted into other units by multiplying said value by the following conversion values.

• During interpolation operation, the speed is stored in the following manner.
Reference axis
Interpolation axis
Refresh cycle: Operation cycle
In case of the single axis operation, "[Md.22] Feedrate" and "[Md.28] Axis feedrate" are identical.
In the composite mode of the interpolation operation, "[Md.22] Feedrate" is a speed in a composite direction
and "[Md.28] Axis feedrate" is that in each axial direction.
The absolute value is displayed in "[Md.22] Feedrate". The operation direction can be checked in "[Md.20]
Feed current value".
■Buffer memory address
Refer to the following for the buffer memory address in this area.

[Md.23] Axis error No.
When an axis error is detected, the error code corresponding to the error details is stored.
• The latest error code is always stored. (When a new axis error occurs, the error code is overwritten.)
• When "1" is set in "[Cd.5] Axis error reset", the axis error No. is cleared (set to "0").
• Monitoring is carried out with a hexadecimal.
