[Md.33] 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 of position control: The composite speed or reference axis speed is stored in the reference axis
address, and "0" is stored in the interpolation axis address.
• During interpolation of speed control: The target speeds of each axis are stored in the monitor of the reference axis and
interpolation axis.
• 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.
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.

The target speed is when an override is made to the command speed.
When the speed limit value is overridden, the target speed is restricted to the speed limit value. The target
speed changes every time data is switched, but does not change in an acceleration/deceleration state inside
each piece of data (changes with the speed change because the target speed changes.)
