See page 9 forspecifications. Table 10 on page 33 describes the control terminals.The drive’s control terminals are referenced to earth ground through a resistor / capacitor network. Usecaution when connecting analog signals not referenced to earth ground, especially if the communicationsport (J3) is being used. The J3 port includes a common reference that can be connected to earth groundthrough the host PLC or computer.Figure 12: Vacon 50X Control TerminalsTerminal DescriptionVmetAnalog output 1, which is a dedicated voltage output.The default signal range is from 0 to 10 Vdc (5 mA maximum). It is proportional to the variableconfigured by parameter 700 (Vmet Config) (see page 79). It may be calibrated while the driveis running via parameter 701 (Vmet Span) (see page 79).ImetAnalog output 2, which is a dedicated current output.The default signal ranges from 0 to 20 mAdc (50 to 500 Ω). It is proportional to the variableconfigured by parameter 702 (Imet Config) (see page 80). It may be calibrated while the drive isrunning via parameters 704 (Imet Offset) and 703 (Imet Span) (see page 80).Vin1Analog Input 1, which is used to provide speed references.The default input signal is 0 to 10 Vdc (the type of input signal is selected with parameter 205(Vin1 Config); see page 64). Parameters 206 (Vin1 Offset) and 207 (Vin1 Span) may be used tooffset the starting value of the range and the size of the range, respectively; see page 64 formore information.If a 0 to 20 mAdc input signal is configured, the burden is 250 ohm. If a 0 to 10 Vdc inputsignal is configured, the input impedance is 475 kohm.A potentiometer with a range of 1 to 2 kohm is suggested for this input.+10 This terminal is a +10 Vdc source for customer-supplied potentiometers. The maximum load onthis supply cannot exceed 10 mAdc.Table 10:Description of Vacon 50X Control Terminals
