5-6 Operation Functions
Ensure that MC3 and MC2 are mechanically interlocked. Otherwise the Inverter may be damaged.
If the earth leakage breaker ELB has tripped because of ground fault, etc. the commercial power
supply circuit will not work, either. If backup is necessary, supply power from a commercial power
supply circuit ELBC.
For FWY, RVY, and CSY, use low-voltage relays. Refer to the above sequence for timing.
If an overcurrent trip occurs at frequency matching, extend the setting of Restart Standby Time
b003.
For the Commercial Switching operation, refer to "Examples of connections and timing of
Commercial Switching operation."
The system can also be set to automatically restart upon power-on. This does not require the CS
terminal. For details, refer to "Reset (RS)" on page 5-100.

Stabilization Parameter

This function is used for adjustment to reduce motor hunting.
In case of motor hunting, check whether motor capacity H003/H203 and motor pole number
selection H004/H204 match your motor. If they do not, match them. If the motor's primary
resistance is smaller than that of the standard motor, increase the H006/H206 set value
gradually. To run a motor with a capacity larger than the Inverter's rated capacity, reduce the
5
set value.
Other than this function, the following methods are suggested to reduce hunting:
Lower the Carrier Frequency (b083). → Refer to "Carrier Frequency" on page 5-51.
Lower the Output Voltage Gain (A045/A245). → Refer to "Output Voltage Gain" on page 5-72.
