By changing the setting of DIP50/60 switch, after the drive inverter has been
powered-down/powered-up, the parameters for the rated motor frequency P0310,
max. frequency P1082 and reference frequency P2000 are automatically pre-set.
In addition, the rated motor parameters as well as all of the other parameters which
depend on the rated motor parameters, are reset. The units of the power
parameters are, depending on P0100, are either interpreted as kW value or hp
value.
NOTE
Switch DIP2(1) (refer to Fig. 3-21) under the I/O board has no function.
3.5.2 Motor
