3.2 Standard Connection Diagram
<2> For floating, impedance grounded, or asymmetrically grounded networks, disconnect the internal EMC filter by moving the SW1
and SW2 screws to the OFF position.
<3> A 24 V power supply option is required to supply power to the control circuit separately from the main circuit.
<4> This figure illustrates an example of a sequence input to S1 through S7 using a non-powered relay or an NPN transistor. Install
the wire link between terminals SC-SP for Sink mode, between SC-SN for Source mode, or leave the link out for external power
supply. Never short terminals SP and SN, as it will damage the drive.
<5> This voltage source supplies a maximum current of 150 mA.
<6> The maximum output current capacity for the +V terminal on the control circuit is 20 mA. Never short terminals +V and AC, as
it can cause erroneous operation or damage the drive.
<7> Use jumper S1 to select between a voltage or current input signal to terminals A1 and A2. The default setting is for voltage
input.
<8> Set DIP switch S2 to the ON position to enable the termination resistor in the last drive in a MEMOBUS/Modbus network.
<9> Monitor outputs work with devices such as analog frequency meters, ammeters, voltmeters, and wattmeters. They are not
intended for use as a feedback-type signal.
<10> Use jumper S5 to select between voltage or current output signals at terminals FM and AM. Set parameters H4-07 and H4-08
accordingly.
