Wiring
● To suppress the surge voltage at the inverter output, connect an output filter. Please contact
your Mitsubishi dealer for more details.
NOTES Especially for long-distance wiring, the inverter may be affected by a charging current
caused by the stray capacitances of the wiring, leading to a malfunction of the overcurrent
protective function or fast response current limit function, or a malfunction or fault of the
equipment connected on the inverter output side.
If fast-response current limit malfunctions, disable this function. Refer to section 6.2.4 for
details of Pr. 156 "Stall prevention operation selection".
Refer to section 6.14.1 for details of Pr. 72 "PWM frequency selection". When using the
optional sine wave filter for the 01800 or more, set Pr. 72 to "25" (25kHz).
