6.3.2 Enabling and downloading the actions
Individual actions can be enabled by clicking in the appropriate check box in the Enable
column. When the PLC Task is activated, only those actions that have been enabled will be
evaluated.
1. Set the required check boxes in the
Enable column.
Now that you have configured and enabled all the conditions you require, they must be
downloaded to the MintDrive
II
.
2. Click
Apply
to download the conditions.
The
Enable
button above the table must be in the on (down) position to activate the PLC Task.
When the PLC Task is not in use it should be switched off to reduce processing power.
3. To activate the PLC Task, click
Enable
at the top of the screen.
Note:
The
button on the mode toolbar can also be used to enable or disable PLC
Task, even if the PLC Task tool is not currently selected.
The controller will now monitor all the conditions for the enabled actions. If the logical result of any
set of conditions becomes true, the corresponding action will be performed. An individual action
can be disabled even while the PLC Task is running. To disable an action that is not required, clear
the action’s enable check box and click
Apply
. Remember to disable the PLC Task when it is not
required, to reduce processing power.
6.3.2.1 Other functions
If the Auto-Enable PLC Task box is checked, the PLC Task will be enabled automatically every
time the drive is reset. This option corresponds to the keyword
PLCAUTOENABLE
; see the Mint
help file for details.
The value in the PLC Time box defines how often the PLC Task is run. This may be set (in
5ms intervals) to a maximum value of 1 second (1000ms). If the evaluation of the PLC Task is
not critical in your application, it is advisable to set PLC Time to a large value. This will reduce
the overall processing time taken by the PLC Task.
The Gear Factor defines the gear factor used by the Fast Gear action; see the Mint help file
topic
PLCGEARFACTOR
for details.
The Jog Speed box can be used to enter a jog speed, expressed in user units. This value is
used by the Jog positive and Jog negative actions. The value in this box is linked to the
Velocity slider shown in Jog mode.
The Clear and Default buttons can be used to either clear or default all conditions.
