The frequency converter drive features two programmable Relay Outputs.ETRElectronic Thermal Relay is a thermal load calculation based on present load and time. Its purpose is to estimate the motor temperature.GLCP:Graphical Local Control Panel (LCP102)InitialisingIf initialising is carried out (par. 14-22), the programmable parameters of the frequency converter return to their default settings.Intermittent Duty CycleAn intermittent duty rating refers to a sequence of duty cycles. Each cycle consists of an on-load and an off-load period. The operation can be eitherperiodic duty or none-periodic duty.LCPThe Local Control Panel (LCP) makes up a complete interface for control and programming of the frequency converter. The control panel is detachableand can be installed up to 3 metres from the frequency converter, i.e. in a front panel by means of the installation kit option.The Local Control Panel is available in two versions:- Numerical LCP101 (NLCP)- Graphical LCP102 (GLCP)lsbLeast significant bit.MCMShort for Mille Circular Mil, an American measuring unit for cable cross-section. 1 MCM 0.5067 mm≡ 2 .msbMost significant bit.NLCPNumerical Local Control Panel LCP101VLT® AQUA Drive Design Guide 1.
