VD560 Series Inverter User Manual Parameter Description
- 165 -
This set of parameters are used to realize the dormancy and wakeup function in water supply
applications.
In the running process of frequency converter, when setting frequency less than or equal to Fb-44
dormancy frequency, after Fb-45 delay time, frequency converter to enter a dormant state, and
automatically stop.
If the frequency converter in a dormant state, and the current running command is valid, then when
setting frequency greater than or equal to Fb-42 wakeup frequency, and the frequency converter
starts up after Fb-43 delay time.
In general, please set the wakeup frequency greater than or equal to dormancy frequency. Set the
wakeup frequency and dormancy frequency is 0.00Hz, then dormancy and wakeup function is invalid.
In dormancy function is enabled, if frequency source use PID, the dormant state PID whether the
arithmetic, influenced by function code FA-29, must be selected PID stop operation (FA-29=1) at this
time.

This group function code is applied to the occations that need inverter output brake, brake release
function. Fb-46 is used to set the detection brake release frequency, Fb-47 was used to detect the
frequency of recovery of the brake. As show in the following figure.

In the process of stop, when the output frequency is less than the value of Fb-48, DO function 41
(timing brake) closed after output the set time of Fb-49. As shown in the figure below.
