IMPORTANT
WARNING
In order to ensure correct and safe operation, it is vital the following instructions are strictly adhered to:
·
Operation of a motor with a higher nominal power than the inverter or a nominal power less than half that of
the inverter is not allowed. The inverter must only be operated when the nominal current in P083 exactly
matches the motor rating plate nominal current.
·
The motor data parameters must be accurately entered (P080-P085) and an auto-calibration performed
(P088=1) before the motor is started. Unstable/unpredictable motor operation (eg. reverse rotation) may
result if this is not done. If this instability occurs, the mains supply to the converter must be disconnected.
When using the analogue input, the DIP switches must be correctly set and the analogue input type selected (P023)
before enabling the analogue input with P006. If this is not done, the motor may start inadvertently.
