VLT ® 2900 Series Display mode Display readout states Quick menu Using the [QUICK MENU] key, it is possible to access the 12 most important parameters of the frequency converter. After programming, the frequency converter is in most cases ready for operation. When the [QUICK MENU] key is activated in Display mode, the Quick menu starts. Scroll through the quick menu using the [+/-] keys and change the data values by first pressing [CHANGE DATA] and then changing the parameter value with the [+/-] keys. TheQuick menu parameters are: In normal operation, one item of operating data can be displayed continuously at the operator's own choice.
By means of the [+/-] keys the following options can be selected in Display mode: - Output frequency [Hz] - Output current [A] - Output voltage [V] - Intermediate circuit voltage [V] Introduction to VLT 2900 - Output power [kW] • Par. 100 Configuration • Par. 101 Torque characteristic - Scaled output frequency f out x p008 • Par. 102 Motor power P M,N Menu mode • Par. 103 Motor voltage U M,N • Par. 104 Motor frequency f M,N In order to enter the Menu mode [QUICK MENU] + [+] must be activated at the same time. In Menu mode, most of the frequency converter pa- rameters can be changed. Scroll through the param- eters using the [+/-] keys.
While scrolling in the Menu mode proceeds, the parameter number will flash. • Par. 105 Motor current I M,N • Par. 106 Rated motor speed n M,N • Par. 107 Automatic motor adaptation • Par. 202 Output frequency high limit f MAX • Par. 203 Reference range • Par. 204 Minimum reference Ref MIN • Par. 205 Maximum reference Ref MAX • Par. 207 Ramp-up time The display shows that the setting in parameter 102 Motor power P M,N is 0.75. In order to change the value of 0.75, [CHANGE DATA] must first be activated; the parameter value can then be changed using the [+/-] keys. • Par. 208 Ramp-down time • Par. 002 Local/remote operation • Par.
003 Local reference Parameter 102 - 106 can be read out from the motor's nameplate. During normal operation the frequency converter is in Auto mode, where the reference signal is given exter- nally, analog or digital via the control terminals. How- ever, in Hand mode, it is possible to give the reference signal locally via the control panel. Hand Auto If for a given parameter the display shows three dots at the right, it means that the parameter value has more than three digits. In order to see the value, acti- vate [CHANGE DATA]. On the control terminals, the following control signals will remain active when Hand mode is activated:
• Hand Start (LCP2) • Off Stop (LCP2) The display shows that in parameter 128 Motor thermal protection the selection made is Thermistor trip [2]. • Auto Start (LCP2) MG.29.A3.02 - VLT ® is a registered Danfoss trademark 9
