3.2 Standard Connection Diagram
<1> Note that if the drive is set to trigger a fault output whenever the fault restart function is activated (L5-02 = 1), then a sequence to interrupt
power when a fault occurs will result in shutting off the power to the drive as the drive attempts to restart itself. The default setting for L5-02
is 0 (fault output not active during restart attempt).
<2> Self-cooling motors do not require wiring that would be necessary with motors using a cooling fan.
<3> Use a three-phase power supply with a voltage of 380 to 480 V for drive models 40720 to 40930 (with stand-alone EMC filter).
<4> The cable between CIMR-U40720 to 40930 and harmonic filter module should not exceed 5 m.
<5> Be sure to wire module connector CN500 to connect the standard configuration device (harmonic filter module) and the models
CIMR-U40720 to 40930 before turning on or operating the models CIMR-U40720 to 40930.
<6> Supplying power to the control circuit separately from the main circuit requires a 24 V power supply.
<7> For control modes that do not use a motor speed feedback signal, PG option card wiring is not necessary.
<8> This figure shows an example of a sequence input to S1 through S8 using a non-powered relay or an NPN transistor. Use jumper S3 to select
the sink mode for the use of an internal power supply or the source mode for the use of an external power supply. Never short terminals SP and
SN as doing so will damage the drive. Refer to
<9> Wire the fault relay output separately from the main circuit power supply and other power lines.
<10> 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.
<11> Set DIP switch S1 to select between a voltage or current input signal to terminal A2. The default setting is for current input.
<12> Enable the termination resistor in the last drive in a MEMOBUS network by setting DIP switch S2 to the ON position.
<13> 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.
<14> 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
Figure 3.52 for instructions.
<15> Disconnect the wire jumper between H1 - HC and H2 - HC when utilizing the Safe Disable input.
<16> Models CIMR-UP and W have terminals 24, 0, and FE. The main circuit power supply can be turned off separately
even when power is supplied to the control circuit.
Note: Be sure to use a stand-alone EMC filter for models CIMR-U40720 to 40930.
