VLT ® 2900 Series On the front of the frequency converter there is a con- trol panel. Control unit [+] / [-] are used for selecting parameters and for changing parameter values. These keys are also used in Display mode for selecting the display of an operating value. The [QUICK MENU] + [+] keys must be pressed at the same time to give access to all parameters. See Menu mode. [STOP/RESET] is used for stopping the connected motor or for resetting the frequency converter after a trip. Can be selected as Active [1] or Not active [0] via pa- rameter 014 Local stop/reset . In Display mode, the display will flash if the stop function is activated. NB!
If the [STOP/RESET] key is set at Not ac- tive [0] in parameter 014 Local stop/re- set, and there is no stop command via the digital inputs or serial communication, the motor can only be stopped by disconnect- ing the mains voltage to the frequency converter. The control panel is divided into four function groups: 1. Six-digit LED display. [START] is used for starting the frequency converter. It is always active, but the [START] key cannot over- ride a stop command. 2. Keys for changing parameters and shifting display function. 3. Indicator lamps. 4. Keys for local operation.
Manual initialisation All displays of data are in the form of a six-digit LED display capable of showing one item of operating data continuously during normal operation. As a supple- ment to the display, there are three indicator lamps for indication of mains connection (ON), warning (WARN- ING) and alarm (ALARM). Most of the frequency con- verter's parameter Setups can be changed immedi- ately via the control panel, unless this function has been programmed as Locked [1] via parameter 018 Lock for data changes . Disconnect mains voltage. Hold the [QUICK MENU] + [+] + [CHANGE DATA] keys down while simultane- ously reconnecting the mains voltage.
Release the keys; the frequency converter has now been program- med for the factory setting. Control keys [QUICK MENU] allows access to the parameters used for the Quick menu. The[QUICK MENU] key is also used if a change to a parameter value is not to be implemented. See also [QUICK MENU] + [+]. [CHANGE DATA] is used for changing a setting. The [CHANGE DATA] key is also used for confirming a change of parameter settings. 8 MG.29.A3.02 - VLT ® is a registered Danfoss trademark
