Figure 8: RESONANCE
With anti-resonance circuitry the motor may be run continuously at speeds where
de-synchronization would otherwise occur. The motor no longer exhibits 'forbidden'
regions where continuous-operation cannot be sustained. And there is more torque
available over the entire operating range of the drive.
The operation of the anti-resonance circuit in most applications is transparent to the
user, in the sense that no special provisions have to be taken to accommodate it. There
are two instances where anti-resonance may be disadvantageous.
1. VERY HIGH SPEED
The anti-resonance circuit limits the maximum speed to 50,000 full steps per
second. Should it be necessary to run the motor faster than that, a special
'anti-resonance disabled' version of the step motor drive can be ordered (a
SUPERIOR ELECTRIC ME61-8001 will exceed 150,000 full step per
second or 45,000 RPM).
