Main circuit terminal specifications
(3) Total wiring length
 Under general-purpose motor control
Connect one or more general-purpose motors within the total wiring length shown in the following table.
200V class
400V class
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.
If that is the case,
use a "400V class inverter-driven insulation-
enhanced motor" and set a frequency in Pr. 72 PWM frequency selection according to the total wiring length shown in the
following table. ( Refer to page 52 to drive a 400V class motor with an inverter.)
 Under IPM motor control
Use the following length of wiring or shorter when connecting an IPM motor.
Use one dedicated IPM motor for one inverter. Multiple IPM motors cannot be connected to an inverter.

NOTE
 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 malfunction or fault of the equipment connected on the inverter output side.
If malfunction of fast-response current limit function occurs, disable this function.
If malfunction of stall prevention function occurs, increase the stall level.
(Refer to page 96 for Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention operation selection )
 When using the automatic restart after instantaneous power failure function for a general-purpose motor with the
wiring length longer than 100m, select "without frequency search" by setting
Pr.162 = "1 or 11." (Refer to page 161)
 The surge voltage suppression filter (FR-ASF-H/FR-BMF-H) option cannot be used under IPM motor control, so do
not connect them.
