Note
● The MD580 series AC drive supports simultaneous temperature sampling in four
channels, each of which supports four types of temperature sensors.
● AI terminals have the multiplexing function. Set the parameters in group F6 for
temperature detection. For specific parameter settings, see software‑related
chapters and sections.
● A temperature drift may be present due to device characteristics when the
temperature sampling circuit works under high or low temperature.
Wiring the relay output terminal
The inductive load (relay, contactor, and motor) causes voltage peak after the current
is disconnected. To minimize the interference at cutoff, use a voltage dependent
resistor (VDR) at the relay contact for protection and absorption circuits such as VDRs,
RC absorption circuits, and diodes on the inductive load, as shown in "

Note
Use a category 2 power supply for the control circuit. Failure to comply may degrade the
operating performance of the AC drive.
