WIRING
(3) Total wiring length
The overall wiring length for connection of a single motor or multiple motors should be within the value in the table below.
* For the 01800 or more, the setting range of Pr. 72 PWM frequency selection is "0 to 6".
When driving a 400V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the
motor terminals, deteriorating the insulation of the motor.
Take the following measures 1) or 2) in this case. (Refer to page 46)
1) Use a "400V class inverter-driven insulation-enhanced motor" and set frequency in Pr. 72 PWM frequency selection
according to wiring length
2) Connect the surge voltage suppression filter (FR-ASF-H/FR-BMF-H) to the or less andthe sine wave filter (MT-
BSL/BSC) to the or more on the inverter outputside.
(4) Cable size of the control circuit power supply (terminal R1/L11, S1/L21)

CAUTION
· 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 function malfunctions, disable this function.
(For Pr.156 Stall prevention operation selection, refer to page 74.)
· For details of Pr. 72 PWM frequency selection , refer to page 164. (When using an optional sine wave filter (MT-BSL/BSC) for the
01800 or more, set "25" in Pr.72 (2.5kHz)).
· For explanation of surge voltage suppression filter (FR-ASF-H/FR-BMF-H) and sine wave filter (MT-BSL/BSC), refer to the
manual of each option.
