4.19 Parameter Group 23-** Time-based Functions
4.19.1 23-0* Timed Actions
Use timed actions for actions performed on a daily or weekly basis, for example different references for working hours/non-working
hours. Up to 10 timed actions can be programmed in the drive. Select the timed action number from the list when entering
parame-
ter group 23-** Time-based Functions
from the LCP.
Parameter 23-00 ON Time
and
parameter 23-04 Occurrence
then refer to the selec-
ted timed action number. Each timed action is divided into an ON time and an OFF time, in which 2 different actions may be per-
formed.
Display lines 2 and 3 in the LCP show the status for timed actions mode (
parameter 0-23 Display Line 2 Large
and
parameter 0-24
Display Line 3 Large
, setting
[1643] Timed Actions Status
).
N O T I C E
A change in mode via the digital inputs can only take place if
parameter 23-08 Timed Actions Mode
is set for
[0] Times Actions Auto
.
If commands are applied simultaneously to the digital inputs for constant OFF and constant ON, the timed actions mode changes
to timed actions auto and the 2 commands are disregarded. If
parameter 0-70 Date and Time
is not set or the drive is set to hand-
on mode or OFF mode (for example via the LCP), the timed actions mode is changed to
[0] Disabled
. The timed actions have a
higher priority than the same actions/commands activated by the digital inputs or the smart logic controller.
The actions programmed in timed actions are merged with corresponding actions from digital inputs, control word via bus, and
smart logic controller, according to merge rules set up in
parameter group 8-5* Digital/Bus
.
N O T I C E
Program the clock (
parameter group 0-7* Clock Settings
) correctly for timed actions to function.
N O T I C E
The PC-based configuration tool VLT® Motion Control Tool MCT 10 comprises a special guide for easy programming of timed
actions.
Parameter 23-00 ON Time
Table 678: Parameter 23-00 ON Time
23-00 ON Time
Default Value: Size related
Parameter Type: Range, 0 - 0
Setup: 2 set-ups
Conversion Index: 0
Data Type: TimeOfDayWoDate
Change during operation: True
Sets the ON time for the desired action.
N O T I C E
The drive has no back-up of the clock function. The set date/time resets to default (2000-01-01 00:00) after a power-down unless
a real-time clockmodule with back-up is installed. In
parameter 0-79 Clock Fault
, it is possible to program a warning if the clock has
not been set properly, for example after a power-down.
