DFM uses pulse voltage as an output monitoring signal;
Duty-cycle: 50%
Min. load impedance R
Max. current endurance: 30 mA
Max. voltage: 30 V ± 1 %

(when 30 V
Max. output frequency: 33 kHz
Current-limiting resistor R: ≥ 1 KΩ
Output load impedance R
Capacitive load ≤ 100 pF
Resistive load ≥ 1 kΩ, resistance determines the output
voltage value.
DFM-DCM voltage = external voltage × (R
The AC motor drive outputs various monitoring signals,
such as drive in operation, frequency reached, and overload
indication through a transistor (open collector).
