4.4 Basic Parameter Adjustments130 YASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07)■ Input Voltage Setting ValueThe input voltage level determines the overvoltage detection level and theoperation level of the braking transistor as shown in the table below.◆ Frequency Reference Source: b1-01This section explains how to assign the frequency reference. Parameters b1-01 andb1-02 can be used to select the source of the run command and the frequencyreference independently, e.g. set the reference from the operator and set the runcommand from the terminals.■ Frequency Reference from the LED Operator (b1-01 = 0)When b1-01 = 0 the frequency reference will be provided by the LED operator.Refer to The Drive and Programming Modes on page 108 for information on howto set the frequency reference.■ Frequency Reference from the Analog Input Terminal: (b1-01 = 1)When b1-01 = 1 the frequency reference will be provided by analog inputs A1 andA2.Note: Analog Input terminals A1 and A2 can both be set to frequency reference at thesame time (H3-02/10 = 0) In this case the addition of both values builds thefrequency reference.VoltageSetting ValueofE1-01(Approximate Values)OVDetectionLevelBrakingTransistorOperationLevelUV Detection Level Desired ACVoltageduring KEBVoltage Levelfor OVSuppression,Stall Prevention200 VClass all settings 410 V 394 V 190 V(single-phase=160 V) 240 V 370 V400 VClasssetting ≥ 400V 820 V 788 V 380 V 480 V 740 Vsetting < 400V 740 V 708 V 350 V 440 V 660 V
