5.10 Base frequency
 : Base frequency 1
 : Base frequency voltage 1
 Function
Set the base frequency and the base frequency voltage in conformance with load specifications or the
base frequency.
Note: This is an important parameter that determines the constant torque control area.

★ If  or  is changed and  trip occur at the frequency that is higher than , the following remedies
are effective.
 Increase the deceleration time .
 If overvoltage limit operation  is set to 0,2 or 3, decrease the over voltage stall protection level
