Timed Actions
Use
for actions needing to be performed on a daily or weekly basis, e.g. different references for working hours / non-working hours. Up
to 10 Timed Actions can be programmed in the frequency converter. The Timed Action number is selected from the list when entering parameter group
23-0* from the LCP. Par. 23-00
ON time and an OFF time, in which two different actions may be performed.
The actions programmed in Timed Actions are merged with corresponding actions from digital inputs, control work via bus and Smart Logic ControllerLogic
Controller, according to merge rules set up in 8-5*O-5#, Digital/Bus.
NB!
The clock (parameter group 0-7*) must be correctly programmed for Timed Actions to function correctly.
