Yaskawa U1000 Industrial MATRIX Drive - Manual (Page 22)

<1> When setting L5-02 to 1 to trigger a fault output whenever the fault restart function is activated, a sequence to interrupt power when a fault occurs
will turn off power to the drive as the drive attempts to restart. The default setting for L5-02 is 0 (Fault output not active during restart attempt).
<2> Self-cooling motors do not require wiring that is necessary for motors using a cooling fan.
<3> Supplying power to the control circuit separately from the main circuit requires 24 V power supply (option).
<4> PG option card wiring is not necessary for control modes that do not use a motor speed feedback signal.
<5> 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.
<6> This voltage source supplies a maximum current of 150 mA when not using a digital input card DI-A3.
<7> Wire the fault relay output separately from the main circuit power supply and other power lines.
<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 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> Set DIP switch S2 to the ON position to enable the termination resistor in the last drive in a MEMOBUS/Modbus network.
<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> Use jumper S3 to select between Sink mode, Source mode, and external power supply for the Safe Disable inputs.
<15> Disconnect the wire jumper between H1 - HC and H2 - HC when utilizing the Safe Disable input.
<16> Models UUoAoooo and UUoPoooo do not have a built-in EMC filter switch.
<17> Models UUoPoooo and UUoWoooo have terminals 24, 0, and FE.
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.
