Trade Size of the Conduit 16(1/2)41(3/2)

Note: Choose the proper size of the Locknut, Bushing corresponding to trade size of the Conduit in use.

Easy Start

When pushing ‘STOP’key for 2~3 seconds in case inverter turns on, the inverter turns into ‘Easy Start mode’with FWD, REV, and STOP command. ‘SHIFT/ESC’can return it to previous mode. Control method: V/F Control frequency: Jog

380-480V Class 55kW (75HP)

Note 1) Rated capacity (v 3×V×I) is based on 220V for 200V class and 460V for 400V class. 2) Indicates the maximum applicable capacity when using a 4-Pole LS motor.3) Maximum output voltage will not exceed the input voltage. An output voltage less than the input voltage may be programmed if necessary.4) IP20/UL Type1 with optional conduit, it can be modified to UL Type1.

Q&A

Q: M7 is Forward Run command (FX). Now I want to do M7 is Reverse Run command (RX). How can I do it,please tell meA: Since M8 has the value of RX, you have to change I/O-26 first as another value which you are not using.The parameters cannot be overlapped.Then please set M7 as reverse run.

Q: Sometimes inverter shows fault Low voltage again sometimes its ok again shows same fault. my motor is also shows good. How can I remove this fault?A: First, Check your inverter Vdc. If your inverter Vdc level is under these voltage (200V Class : 180Vdc / 400V Class 360Vdc), Low voltage can occurs. Second, Check M/C in inverter. M/C in inverter has trouble, Low voltage can occur. In case of this situation, you have to change the PCB.

Q: Inverter shows fault Out Phase Open how can I solve this problem? inverter remedy says output (u v w) phase is open how can I this fault.A: Out Phase Open are shown when one or more of the output (U, V, W) phase is open or has high difference in current between each cable.Check motor if it is okay, and check each U,V,W's current to see if it is sending out different level of current and check cable. If those two does not have any problem, then our iS5's current measuring component might have problem.
