4 1. Safety Precautions - Precautions de securité WARNING/ATTENTION! According to the EEC standar ds the A V300i should be used only after checking that the mechanical equipment uses safety devices requir ed by the 89/392/EEC set of rules. Drive systems cause mechanical motion. It is the responsibility of the user to insur e that any such motion d[...]

5 CAUTION / PRECAUTION: Do not operate the drive without a ground wir e being connected. The motor chassis should be gr ounded to earth through a gr ound lead separate fr om all other equipment ground leads to pr event noise coupling. The grounding connector shall be sized in accor dance with the NEC or Canadian Electrical Code. The connection shal[...]

6 6. A capacitative load (e.g. variable power factor capacitors) should not be connected to the output of the drive (terminals U2, V2, W2). Aucune charge capacitive ne doit être connectée à la sortie du convertisseur (bornes U2, V2 et W2) (par exemple des condensateurs de mise en phase). 7. Always connect the drive to the protective gr ound (PE)[...]

17 7. Pre Power Checks The following should be checked before switching ON the Drive : Grounds / Gr ounding • V erify ground connections between the drive and motor • V erify AC Input, AC Output and control wiring ar en’t grounded Connections • V erify AC Input (U1/L1, V1/L2, W1/L3), AC Output (U2/T1, V2/T2, W2/T3), DC link connection (C,D)[...]

18 8. Quick tuning 1. After a complete check of wiring, turn the power on: • The following voltages must be present: T erminal 7, +10V to terminal 9 (on regulation board) T erminal 8, -10V to terminal 9 (on regulation boar d) T erminal 19, +24…30V to terminal 18 (on regulation boar d) • Check DC link voltage by pressing [Down arrow] to get ?[...]

19 of this is trying to [Enter] a value for “Nominal Current that is less than 30% of the drive rating. This is not allowed due to problems encounter ed with a small motor and a lar ge drive.

20 NOTE: “xxx range error” or “timeout” messages may also occur in some extr eme parameter ranges. Repeat the tune in this case. If error messages ar e persistent see troubleshooting section. If there was some r eason you did not want to keep these values permanently , but only wanted to try to run the drive with them, ther e is no need to [...]

22 9. Options Encoder verification: Set the Drive in V/f mode and run the motor , enable and start the drive and set an analog refer ence. If the refer ence is positive on terminal 1 with respect to 2 (common) the motor should be turning clockwise.

27 Undervoltage Line voltage parameter incorr ectly set. Remedy: set parameter correctly and then acknowledge the failure via RESET*. The incoming voltage to the power section of the device is too low due to: - too low an AC input voltage or extr eme line dips - poor cable connections (e.g. terminals on contactor , choke, filter ... not properly ti[...]
