Base Frequency

Base Frequency and Motor Voltage

Match the Inverter output (frequency/voltage) to the motor rating. Be careful, especially if you set a
base frequency at below 50 Hz. Otherwise, the motor may burn out.

Related parameters
* To switch to the 2nd base frequency, allocate 08 (SET) to the multi-function input terminal and then turn it on.
•ISelect the motor voltage according to the motor specifications. If the voltage exceeds the specified
level, the motor may burn out.
•The Inverter cannot output voltage beyond that of the incoming voltage.

Maximum Frequency

Set the maximum value of the output frequency.
•The value set here will be the maximum value (e.g.,10 V in the range from 0 to 10 V) of the external
analog input (frequency reference).
•The maximum Inverter output voltage from base to maximum frequencies is the voltage set at AVR
voltage selection A082.
•The Inverter cannot output voltage beyond that of the incoming voltage.
