我找了机械供应商对变频器的控制要求如下：Speed control
Constancy of operating speed ± 0.02%.
Constancy of relative speed difference of two adjacent groups ≤ 0.01%.
These data are related to the maximum machine speed and the mains conditions defined in industrial systems and, thus, to normal operating conditions.
Dynamic speed deviation - With a load variation of ± 10%, the maximum speed deviation of the variable-speed drive / tension-controlled drive shall lie within the limits of ± 0.05% of the maximum value and the correction time shall be approx.
1 to 4 seconds, depending on the mass moment of inertia of the group involved.
