3.2 Standard Connection Diagram
<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.
<11> Disconnect the wire jumper between H1 - HC and H2 - HC when utilizing the Safe Disable input.
<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.
Note: Although no fault may be present, the drive cannot be started under certain conditions such as when the Digital Operator is left in
the Programming Mode. Use the "Drive Ready" output (default set to terminals M5-M6) to interlock operation in such situations.
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.
