<5> Supplying power to the control circuit separately from the main circuit requires a 24 V power supply (option).
<6> For control modes that do not use a motor speed feedback signal, PG option card wiring is not necessary.
<7> 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.
<8> The maximum output current capacity for the +V and -V terminals on the control circuit is 20 mA. Never short
terminals +V, -V, and AC, as it can cause erroneous operation or damage the drive.
<9> Set DIP switch S2 to the ON position to enable the termination resistor in the last drive in a MEMOBUS/
Modbus network.
<10>The sink/source setting for the Safe Disable input is the same as with the sequence input. Jumper S3 has the
drive set for an external power supply. When not using the Safe Disable input feature, remove the jumper
shorting the input and connect an external power supply. Refer to
Sinking/Sourcing Mode Selection for Safe
for instructions.
<11> Disconnect the wire jumper between H1 - HC and H2 - HC when utilizing the Safe Disable input. Terminals
H1, H2, DM+, and DM- on 600 V class models are designed to the functionality, but are not certified to IEC/
EN 61800-5-1,ISO/EN 13849 Cat.3, IEC/EN 61508 SIL2, Insulation coordination: class 1.
<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 of signal.
<13>When the drive is set to trigger a fault output upon activation of the fault reset function (L5-02 = 1), a
sequence to interrupt power when a fault occurs will shut off the power to the drive when the drive attempts a
reset. The default setting for L5-02 is 0 (fault output not active during reset attempt).
<14>Wire fault contact outputs MA, MB, and MC. Wire so that a fault will open the safety circuit and interrupt
drive output.
<15>When using the Programming Mode to edit parameter settings, L1000A will not accept an Up/Down
command. If the drive still will not run when an Up/Down command has been entered and no fault is present,
then use the "Drive ready" signal (the default setting for terminal M5-M6) to interlock components.
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.
NOTICE: When using the automatic fault reset 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 reset (L5-02 = 0, default). Failure to comply will prevent the automatic fault reset
function from working properly.
