3.9 Control Circuit Wiring
76 YASKAWA ELECTRIC TOEP C710656 07C YASKAWA Power Regenerative Converter - D1000 Instruction Manual
◆ Control Circuit Terminal Block Functions
Parameters determine which functions apply to the multi-function digital inputs (S1 to S8), multi-function relay outputs
(M1, M2, M3, M4, M5, M6), and multi-function analog monitor outputs (FM, AM). The default setting is listed next to
each terminal name in
Table 3.8 .
NOTICE: Install an MC on the power supply side of the converter when the drive should not automatically restart after power loss. To
get the full performance life out of the electrolytic capacitors and circuit relays, refrain from switching the power supply off and on more
than once every 30 minutes. Frequent use can damage the converter.
■ Input Terminals
Table 3.8 lists the input terminals on the converter. Text in parenthesis indicates the default setting for each multi-function
input.
Table 3.8 Control Circuit Input Terminals
<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 81 .
<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.
