Connection examples of two-wire and three-wire sensors
PID macros (see ACS560 firmware manual (3AXD50000016097 [English])) use
analog input 2 (AI2). The macro wiring diagrams on these pages use an externally
powered sensor (connections not shown). The figures below give examples of
connections using a two-wire or three-wire sensor/transmitter supplied by the
drive auxiliary voltage output.
Note: Maximum capability of the auxiliary 24 V DC (250 mA) output must not be
exceeded.

Note: Maximum capability of the auxiliary 24 V DC (250 mA) output must not be
exceeded.
Note: The sensor is supplied through its current output and the drive feeds the supply
voltage (+24 V DC). Thus the output signal must be 4…20 mA, not 0…20 mA.
