Data Carrier Speed

Calculation Example
Max. DC Speed =
24
The number of bytes that can be processed using the Auto Read and Auto Write
commands depends on the speed of the DC. The relationship between the num-
ber of bytes and DC speed in m/minute can be determined from the following
equation.
Max. DC Speed =
• The "distance travelled in the transmission range (m)" is the maximum width of
the transmission range (in the X direction). Refer to the diagrams in 3-1 Trans-
mission Range.
• The "lower-level transmission time (min)" is the time required for transmission
between the DC and the R/W Head. For details regarding this calculation, refer
to 3-2 Transmission Time.
In this example diagram, the V600-D8KR04 and V600-H07 are combined and
four bytes are read.
This diagram shows the following:
Distance travelled in transmission range, Y (transmission distance) = 110 mm
Lower-level transmission time, T = 1.8 x 4 + 48.4 = 55.6 ms.
Accordingly, the DC speed in this case will be as follows:
Distance travelled in the transmission range (m)
Lower-level transmission time (min)
Note 1. The distance travelled in the transmission time will vary depending on the
read/write distance and the shaft slippage. Refer to the diagrams in 3-1
Transmission Range.
2. The DC speed is the standard value. Before using the equipment, run a test
to determine the speed under the actual operating conditions.
3. The DC speed data above do not take into account possible transmission
errors in host or lower-level communications.
4. When the V600-CA8A/CA9A is used, the speed will vary depending on the
software at the host device.
