VACON® 3000
Application Guide
With this parameter, it is possible to set limits for the "skip frequency" region.
7.92 (ID 511) Prohibit Frequency Range 2 Low Limit
Location in the menu:
•
INU application: P3.7.3
Use this parameter to prevent the drive operating on the prohibited frequencies. In some processes, it can be necessary to avoid
some frequencies because they cause mechanical resonance.
With this parameter, it is possible to set limits for the "skip frequency" region.
7.93 (ID 512) Prohibit Frequency Range 2 High Limit
Location in the menu:
•
INU application: P3.7.4
Use this parameter to prevent the drive operating on the prohibited frequencies. In some processes, it can be necessary to avoid
some frequencies because they cause mechanical resonance.
With this parameter, it is possible to set limits for the "skip frequency" region.
7.94 (ID 513) Prohibit Frequency Range 3 Low Limit
Location in the menu:
•
INU application: P3.7.5
Use this parameter to prevent the drive operating on the prohibited frequencies. In some processes, it can be necessary to avoid
some frequencies because they cause mechanical resonance.
With this parameter, it is possible to set limits for the "skip frequency" region.
7.95 (ID 514) Prohibit Frequency Range 3 High Limit
Location in the menu:
•
INU application: P3.7.6
Use this parameter to prevent the drive operating on the prohibited frequencies. In some processes, it can be necessary to avoid
some frequencies because they cause mechanical resonance.
With this parameter, it is possible to set limits for the "skip frequency" region.
