62 CHA NGE PARA METERS

6.1.5 C ALIBRA TION / Base rated motor rpm PIN 5 QUICK ST ART

This value is usually found on the motor dataplate.

6.1.6 C ALIBRA TION / Desired max rpm PIN 6 QUICK ST ART

This represents 100% speed.

If your DESIRED M A XIMUM RPM is higher than the BA SE RA TED RPM then you will need to implement field

weakening in the CHANGE PARAMETERS / FIELD CONTROL menu. You must ho wever verify that your motor

and load are rated for rotation above base speed. Failure to do so may result in mechanical failure with

disastrous consequences.

If ho wever your desired maximum rpm is lo w compared to the base rpm then you need to be a w are of the

heat dissipation in the motor at full torque. Use force venting of the motor if necessary.

6.1.7 C ALIBRA TION / Zero speed offset PIN 7

This is useful if your speed feedback is derived from an external amplifier which may have a small offset.

If this parameter is adjusted un-necessarily then it will appear as an offset on the speed feedback. See 7.1.10

SPEED LO OP MONIT OR / Speed feedback % monitor PIN 131.
