<1> Supplying power to the control circuit separately from the main circuit requires 24 V power supply (option).
<2> This figure illustrates an example of a sequence input to S1 through S8 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.
<3> Wire the fault relay output separately from the main circuit power supply and other power lines.
<4> The maximum output current capacity for the +V terminal on the control circuit is 20 mA. Never short terminals +V or AC, as it can cause erroneous
operation or damage the drive.
<5> Set jumper S1 to select between a voltage or current input signal to terminal A2. The default setting is for current input.
<6> Set jumper S1 to select between a voltage or current input signal to terminal A1 and A3. The default setting is for current input.
<7> Set DIP switch S2 to the ON position to enable the termination resistor in the last drive in a MEMOBUS/Modbus network.
<8> Use jumper S5 to select between voltage or current output signals at terminals AM and FM. Set parameters H4-07 and H4-08 accordingly.
<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.
