A Data Calculation Standards - Omron C200HW Operation Manual

This section explains the internal processing of the C200HW-NCj13 Position Control Unit, so it can be used as a
reference. The performance values shown in this section are the measurements results obtained under the follow-
ing conditions.
PC: C200HX-CPU44-E (with no Expansion or Remote Racks)
Position Control Unit: Only one Unit is mounted on the CPU Rack.
Note The performance values shown in this section will vary depending on conditions such as the configuration
and settings of the PC, the user program, and other mounted Units, so use these values for reference 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.
Actual speed (pps) =
Note Round: Function for rounding the value.

pps: Pulses per second
16 MHz
±0.02%
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 pro-
cessing and be ready to recognize the START command is approximately 800 ms.
