★ The inverter was factory-configured by default so that shorting terminals F-CC and terminals R-CC
simultaneously would cause the motor to slow down to a stop.
Using the parameter , however, you can select between forward run and reverse run.
5.8 Maximum frequency
: Maximum frequency
 Function
1) Programs the range of frequencies output by the inverter (maximum output values).
2) This frequency is used as the reference for acceleration/deceleration time.

★ If  is increased, adjust the upper limit frequency  as necessary.
★ 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
