3.9 Control Circuit Wiring
NOTICE:
Do not connect AC control circuit ground to regenerative unit enclosure. Improper regenerative unit grounding can cause
control circuit malfunction.

<1> Set jumper S3 to change the sequence input signals (S1 to S8) between sinking and sourcing inputs. The default setting is for
Sinking Mode. Control is possible with no-voltage contacts or NPN transistors. For details, refer to
<2> The maximum output current capacity for the +V and -V terminals on the control circuit is 20 mA. Never short terV, -V,
and AC, as it can cause erroneous operation or damage the regenerative unit.
<3> Set DIP switch S1 to select between a voltage or current input signal to terminal A2. The default setting is for current input. For
details, refer to
Terminal A2 Input Signal Selection on page 57
.
<4> Set DIP switch S2 to the ON position to enable the termination resistor in a MEMOBUS/Modbus network.
<5> 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.
