Wiring
NOTES Note that the motor windings are subjected to significantly higher loads when the motor is
operated by inverter than with normal mains operation. The motors must be approved for
inverter operation by the manufacturer (refer also to section 3.8.4).
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, fast response current limit function, or stall prevention function or a mal-
function or fault of the equipment connected on the inverter output side.
If fast-response current limit malfunctions, disable this function. When the stall prevention
function misoperates, increase the stall level. (Refer Pr. 22 "Stall prevention operation level"
and Pr. 156 "Stall prevention operation selection".)
Refer to section 6.15.1 for details of Pr. 72 "PWM frequency selection".
When using the automatic restart after instantaneous power failure function with wiring
length exceeding than 100m, select without frequency search (Pr. 162 = "1, 11").
