VLT ® 2900 Series NB! In remote operation (parameter 002 Lo- cal/remote operation ) the start/stop state at the time of mains connection will de- pend on the external control signals. If Pulse start [8] is selected in parameter 302 Digital input , the motor will remain stop- ped after mains connection. Not locked (NOT LOCKED) [0] Locked (LOCKED) [1] In this parameter, it is possible to 'lock' the controls to disable data changes via the control keys. If Locked [1] is selected, data changes in the parame- ters cannot be made; however, it will still be possible to make data changes via serial communication. Pa- rameter 009-012 Display readout can be changed via the control panel.
Not active (DISABLE) [0] Active (ENABLE) [1] In this parameter you can select whether it should be possible or not to switch between Auto- and Hand mode. In Auto mode the frequency converter is con- trolled by external signals whereas the frequency con- verter in Hand mode is controlled via a local reference directly from the control unit. Auto restart, use saved reference (AUTO RESTART) [0] Programming Forced stop, use saved reference (LOCAL=STOP) [1] If Not active [0] is selected in this parameter, the Hand mode function will be inactive. If Active [1] is selected you can switch between Auto- and Hand mode. For further information, see the Control Unit section. Forced stop, set ref.
to 0 (LOCAL=STOP, REF=0) [2] Setting of the required operating mode when the mains voltage is engaged. This function can only be active if Local operation [1] has been selected in parameter 002 Local/remote operation . Auto restart, use saved ref. [0] is selected if the fre- quency converter is to start using the local reference (set in parameter 003 Local reference ) and the start/ stop state given via the control keys immediately prior to the mains voltage being cut out. Forced stop, use saved ref. [1] is selected if the fre- quency converter is to remain stopped when the mains voltage is engaged, until the [START]-key is activated.
After a start command the motor speed is ramped up to the saved reference in parameter 003 Local refer- ence . Forced stop, set ref. to 0 [2] is selected if the frequency converter is to remain stopped when the mains voltage is cut back in. Parameter 003 Local reference is to be zeroed. Not active (Disable) [0] Active (Enable) [1] In this parameter you can select the standard setup of the Quick menu key on the control panel and the LCP 2 control panel. Using this function, in parameter 025 Quick Menu set- up the user can select up to 20 parameters for the Quick Menu key. If not active [0] is selected, the standard setup of the Quick Menu key is active.
