Procedure
When an online connection to the drive unit has been established, the bar in the header area of
the screen form has a colored background. The control elements are grayed-out – with the
exception of the "Activate" button. The remaining control elements become active after you
have activated the control panel and set the enable signals.
Figure 5-15
When you activate the control panel, you assume master control of the drive. When you
deactivate the control panel, you return the master control. The control panel can always only
be activated for one drive.
Activating the control panel
To activate the control panel, proceed as follows:
1. Click the "Activate" button at "Master control".
The "Activate master control" message window opens.
2. Carefully read the warning note and check the value of the monitoring time.
The monitoring time specifies the time during which the connection from the PG/PC to the
drive is cyclically monitored. The minimum value is 1000 ms.
3. Click "Continue" to confirm the monitoring time.
The message window closes.
The control panel is active.
Activating the infeed unit
If an infeed unit is available in your drive, then the infeed must also be activated. If it is not
activated, no further drive release can be set.
Click the "1" icon at "Infeed" to switch on the infeed.
