3.1 Standard Connection Diagram
<1> Remove the jumper when installing a DC link choke. Models 2A0110 to 2A0415 and 4A0058 to 4A1200 come with a built-in DC link choke.
<2> Set L8-55 to 0 to disable the protection function of the built-in braking transistor of the drive when using an optional regenerative converter or
dynamic braking option. Leaving L8-55 enabled may cause a braking resistor fault (rF). Additionally, disable Stall Prevention (L3-04 = 0) when
using an optional regenerative converter, regenerative or braking units, or dynamic braking option. Leaving If L3-04 enabled may prevent the drive
from stopping within the specified deceleration time.
<3> Supplying power to the control circuit separately from the main circuit requires 24 V power supply (option).
<4> 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.
<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> Set jumper S1 to select between a voltage or current input signal to terminal A2. The default setting is for current input.
<8> Set jumper S1 to select between a voltage or current input signal to terminal A1 and A3. The default setting is for voltage input.
<9> Set DIP switch S2 to the ON position to enable the termination resistor in the last drive in a MEMOBUS/Modbus network.
<10> H2-02 Default = F (Through Mode) in drive software versions PRG: 8551 and earlier.
<11> Use jumper S5 to select between voltage or current output signals at terminals AM and FM. Set parameters H4-07 and H4-08 accordingly.
<12> 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.
WARNING! Sudden Movement Hazard. Do not close the wiring for the control circuit unless the multifunction input terminal parameters are
properly set. Improper sequencing of run/stop circuitry could result in death or serious injury from moving equipment.
WARNING! Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the correct state before energizing
the drive. Failure to comply could result in death or serious injury from moving equipment. When programmed for 3-Wire control, a momentary
closure on terminal S1 may cause the drive to start.
WARNING! Sudden Movement Hazard. Confirm the drive I/O signals and external sequence before executing the application preset
function. Executing the application preset function or setting A1-03 ≠ 0 will change the drive I/O terminal functions and may cause unexpected
equipment operation. Failure to comply may cause death or serious injury.
NOTICE: When using the automatic fault restart function with wiring designed to shut off the power supply upon drive fault, make sure the
drive does not trigger a fault output during fault restart (L5-02 = 0, default). Failure to comply will prevent the automatic fault restart function
from working properly.
