DANGER

HAZARD OF ELECTRIC SHOCK OR ARC FLASH

• During auto-tuning, the motor operates at rated current.
• Do not service the motor during auto-tuning.
Failure to follow these instructions will result in death or serious injury.
WARNING
LOSS OF CONTROL
• It is essential that the following parameters UnS, FrS, nCr, nSP, and nPr or COS are correctly
configured before starting auto-tuning.
• When one or more of these parameters have been changed after auto-tuning has been performed, tUn will
return nO and the procedure will have to be repeated.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

vDone: If auto-tuning has already been performed
Attention:
• Auto-tuning must be performed with the motor connected and cold.
• Parameters Rated Motor Power nPr page 46 and Rated motor current nCr page 57 must be
consistent.
• Auto-tuning is performed only if no stop command has been activated. If a freewheel stop or fast stop
function has been assigned to a logic input, this input must be set to 1 (active at 0).
• Auto-tuning takes priority over any run or prefluxing commands, which will take effect after the auto-
tuning sequence.
• Auto-tuning may last for 1 to 2 seconds. Do not interrupt, wait for tUn value to change to dOnE or
nO.
Note: During auto-tuning the motor operates at rated current.
