(or a sub-branch within it) in the browse tree pane. Controlling Drives DriveWindow 2 5-5 If control could be taken successfully, status image and name of the drive, field for entering the reference value, and command buttons are shown in the drive panel toolbar. The status image of the drive in the browse tree pane will be refreshed even if drive status refreshing is off. Also, control commands in the Drive menu are enabled, and the Take Control command has toggled to Release Control. If the drive under control does not have a command available, the corresponding button in the drive panel toolbar is hidden, and in the Drive menu it is disabled (grayed). AC and DC drives reuse some positions to show buttons for different commands, which do not exist in the other type of drive. The commands shown in the Drive menu are changed correspondingly. By default, the items in the control item set are shown and put on-line. Controlling Drives 5-6 DriveWindow 2 2.1.1 Losing control If the watchdog in the drive goes off for some reason, or there is a communication failure, your PC beeps and control is automatically released. The fault logger usually logs a PANEL LOSS fault in such a case. 2.1.2 Disabled operations To minimize the probability of losing control, some operations, which may cause heavy communication load, are disabled, while control is taken. For example, the following operations are disabled: ? Saving, comparing, exporting, printing, and downloading of drive parameters. ? Uploading, restoring, and downloading system software. See Also: Controlling Drives Taking and Releasing Control Commanding a Drive Release Control 2.2 Release Control When you do not need to control a drive any more, you should release the control. Before releasing control, we recommend, if possible, to set the reference value to zero and stop the drive. To release control of a drive, select first the drive by clicking it in the browse tree pane. It is not necessary to select its root, however. Selection of any of its sub-branches will do. Then either, click the take/release control button in the drive panel toolbar, select the Release Control command in the Drive menu, or press Alt+F2. Controlling Drives DriveWindow 2 5-7 The Release Control command can also be found in the context menu, which you get by clicking with the right mouse button the drive (or a sub-branch within it) in the browse tree pane. If control could be released successfully, the drive panel toolbar is cleared. Also, control commands in the Drive menu are disabled (grayed), and the Release Control command has toggled to Take Control.
