Chapter 5. DETAILED DESCRIPTION OF EACH FUNCTION
• The initial value of the time proportional cycle 1 (
Cy
) is “10” when the control
output 1 is the relay output and it is “2” in other cases.
• The initial value of the time proportional cycle 2 (
Cy2
) is “10” when a model
with one control output point is used and it is “2” when other models are used.
• The setting of the time proportional cycle mode (
tP.ty
) is valid to the time
proportional outputs of both MV1 and MV2.
• When MV1 is connected to the relay control output or event output in the DO
Assignment and the time proportional cycle 1 (
Cy
) is set at less than “5s”, the
operation is performed at intervals of 5s.
• When MV2 is connected to the relay control output or event output in the DO
Assignment and the time proportional cycle 2 (
Cy2
) is set at less than “5s”, the
operation is performed at intervals of 5s.
Handling Precautions
• The following shows the resolution of the time proportional output by
the setting of the time proportional cycle unit 1 and 2 (
CyU
/
CyU2
):
When this setting is set at “0” (1s unit), the resolution becomes
“1/1000” (seconds of the time proportional cycle × 1/1000).
When this setting is set at “1” (Cycle fixed at “0.5s”), the resolution
becomes “1/500 (1ms)”.
When this setting is set at “2” (Cycle fixed at “0.25s”), the resolution
becomes “1/250 (1ms)”.
When this setting is set at “3” (Cycle fixed at “0.1s”), the resolution
becomes “1/100 (1ms)”.
• The time proportional cycle is operated for a period of time
approximately 2.4% longer than the setting. Care should be taken when
using the timer function with the time proportional output. Use the ON
delay/ OFF delay and DI timer stop/start functions with the timer function
of the internal event, if the ON/OFF output having more precise time is
needed.
