Figure 3.34 Control Circuit Connection Diagram (example: CIMR-UA20028/UD20028/UT20028)
<1> 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 or the source mode, and internal or external power supply.
<2> Wire the fault relay output separately from the main circuit power supply and other power lines.
<3> The maximum output current capacity for the +V and -V terminals on the control circuit is 20 mA. Never short terminals +V, -V, a n d
AC, as this can cause erroneous operation or damage the drive.
<4> Set DIP switch S1 to select between a voltage or current input signal to terminal A2. The default setting is for current input.
<5> Enable the termination resistor in the last drive in a MEMOBUS network by setting DIP switch S2 to the ON position.
<6> 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.
<7> The sink/source setting for the Safe Disable input is the same as with the sequence input.
