Parameter Descriptions

12-13

.

Sets the highest voltage the drive will output.

Sets the maximum allowable frequency the drive will output. Note
that is not maximum speed, which is set in parameter 82. Refer to
figure 12.4.

Maximum Speed (82) + Overspeed Limit (83) must be

≤ Maximum Freq (55).
