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! When 3-Wire sequence is used, set the drive to 3-Wire sequence before wiring the control terminals and ensure
parameter b1-17 is set to 0 (drive does not accept a run command at power up (default). If the drive is wired for 3-Wire sequence but
set up for 2-Wire sequence (default) and if parameter b1-17 is set to 1 (drive accepts a Run command at power up), the motor will
rotate in reverse direction at power up of the drive and may cause injury.
WARNING! When the application preset function is executed (or A1-06 is set to any value other than 0) the drive I/O terminal functions
change. This may cause unexpected operation and potential damage to equipment or injury.
WARNING! When using the automatic fault restart function while the wiring is made to shut off the power supply when a drive fault
occurs, make sure the drive is set not to trigger a fault output during fault restart (L5-02=0, default). Otherwise the fault restart function
can not work properly.
NOTICE: Do not connect more than one multi-function input to one terminal. Improper wiring may result in drive malfunction. Use an
external power supply when sharing a terminal with more than one input. Do not use the built-in +24 V power supply.
<7> Available slide switch S6 is models ETC740310 and ETC740311.
<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
this can cause erroneous operation or damage the drive.
<9> Set DIP switch S1 to select between a voltage or current input signal to terminal A2. The default setting is for current input.
<10> Set DIP switch S4 to select between analog or PTC input for terminal A3.
<11> Enable the termination resistor in the last drive in a MEMOBUS network by setting DIP switch S2 to the ON position.
<12> Use jumper S3 to select between Sink mode, Source mode or external power supply for the Safe Disable inputs.
<13> Disconnect the wire jumper between H1 - HC and H2 - HC when utilizing the Safe Disable input.
<14> 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.
<15> Use jumper S5 to selection between voltage or current output signals at terminal AM and FM. Set parameters H4-07 and H4-08 accordingly.
<16> Slide the switch S6 to select N.C. or N.O. as the state of the DM+ and DM- terminals for EDM output.
