Main circuit terminal specifications

NOTE

y 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 fast-response current limit malfunctions, disable this function. When the stall prevention function misoperates,

increase the stall level. ( Refer to Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention operation selection in

the chater 4 of the Instruction Manual)

y Refer to the chater 4 of the Instrunction Manual for details of Pr. 72 PWM frequency selection . Refer to the manual of the

option for details of surge voltage suppression filter (FR-ASF-H/FR-BMF-H).

y When using the automatic restart after instantaneous power failure function with wiring length exceeding below,

select without frequency search (Pr. 162 = "1, 11"). (

Refer to the chater 4 of the Instruction Manual)
