Restrictions and precautions for parameter setting
For simple variable-speed operation of the inverter, the initial values of the parameters may be used as they are. Set the necessary parameters to meet the load
and operational specifications. Parameter setting, change and check can be performed from the operation panel (FR-DU08).
NOTE
• For the parameters not found in this Instruction Manual, refer to the Instruction Manual (Detailed) of the FR-A800 inverter.
• The initial values of the following parameters in the FR-B or FR-B3 inverter are different from those in the FR-A800 inverter because the values change
depending on the applied motor.
• Settings of the following parameters are restricted to satisfy the explosion-proof specifications. Always use the parameters under restrictions.
The following regeneration unit can be used.
