Information on commissioning of the ErgoSpin hand-held nutrunner and the tightening spindle
CAUTION
Risk of property damage and personal injury due to incorrect motor
alignment
If the output drive is blocked during first start-up of the ErgoSpin hand-held nutrunner or the
tightening spindle, the function of the tightening channel may be compromised and increased heating
of the motor, reduced performance and reversed spin direction during the next tightening operation
may occur. Additionally, a system error class 3 (error code 122) is returned. In current-controlled
systems, this may also lead to incorrect evaluation of results.
 Make sure that the output drive can freely rotate after switching on the tightening channel, restart
of the servo amplifier and after connection of the ErgoSpin hand-held nutrunner or the tightening
spindle. Completion of motor alignment is indicated by brief vibration (1 s) of the ErgoSpin hand-
held nutrunner or the tightening spindle.
 If nutrunner docking is activated, the motor is realigned after each docking operation. Make sure
that the output drive can freely rotate after docking.
