Performance Characteristics
Note
The performance values shown in this section will vary depending on conditions such as the configura-
tion and settings of the PLC, the user program, and other mounted Units, so use these values for refer-
ence only.
Speeds
Due to internal processing, the following difference occurs between the value set as the speed (frequency) and
the value actually output from the Unit.
This difference occurs because a 16-MHz source clock is divided by the pulse output LSI divider. An error of
±
0.02% also occurs because the source clock is affected by factors such as the temperature. However, this
does not affect the positioning accuracy.
Note
An additional error of
±
0.02% max. occurs in the actual speed.
Power Up Time
When the Position Control Unit is powered up or restarted, the time required for the Unit to complete its initial
processing and be ready to recognize the START command is approximately 240 to 300 ms.
