What is meant by cycle time (Cy)?

The switching cycle time is quoted in seconds and defines the period during which a full switching cycle consisting of switch-on and switch-off times takes place.

Generally, the cycle time should be selected so that the actual control process can still be smoothed out. At the same time, the switching frequency must always be taken into account.
The response can best be reset in manual mode so that the direct influence of the manipulating variable on the cycle time can be monitored. With a manipulating variable of 50 %, "Ton" and "Toff" are equal. If the manipulating variable is altered, this ratio alters accordingly.
