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. When using a 3-Wire sequence, set the drive to 3-Wire sequence prior to wiring the control
terminals and set parameter b1-17 to 0 so the drive will not accept a Run command at power up (default). If the drive is wired for a 3-
Wire sequence but set up for a 2-Wire sequence (default), and parameter b1-17 is set to 1 so the drive accepts a Run command at
power up, the motor will rotate in reverse direction at drive power up and may cause injury.
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 A1-06 ≠ 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.
NOTICE: Do not connect AC control circuit ground to drive enclosure. Improper drive grounding can cause control circuit malfunction.
<5> This voltage source supplies a maximum current of 150 mA when not using a digital input card DI-A3.
<6> 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.
<7> Set DIP switch S1 to select between a voltage or current input signal to terminal A2. The default setting is for current input.
<8> Set DIP switch S4 to select between analog or PTC input for terminal A3.
<9> Set DIP switch S2 to the ON position to enable the termination resistor in the last drive in a MEMOBUS/Modbus network.
<10> Use jumper S3 to select between Sink mode, Source mode, and external power supply for the Safe Disable inputs.
<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 signal.
<13> Use jumper S5 to select between voltage or current output signals at terminals AM and FM. Set parameters H4-07 and H4-08 accordingly.
<14> Self-cooling motors do not require the same wiring necessary for motors with cooling fans.
