Functions
(Example 1) 0-Hz start
(Example 2): Frequency matching start
• The Inverter starts running at 0 Hz regardless of the
motor rpm. The retry wait time is ignored at 0-Hz
start.
• If the Inverter starts running at 0 Hz with the motor
rpm high, an overcurrent trip may occur.
• When the FRS terminal is turned off and the retry wait
time elapses, the motor frequency is matched and a
frequency pull-in starts without stopping the motor. If
an overcurrent trip occurs at frequency matching
start, extend the retry wait time.
• Even if "frequency matching start" is selected, the
Inverter may start at 0 Hz when:
• The output frequency is equal to or lower than
1/2 of the base frequency
• The motor induction voltage quickly attenuates
• The Inverter detects a frequency equal to or
lower than the frequency matching lower limit
frequency setting (b007)

(Example 3) Frequency pull-in restart
• After the retry wait time (b003) elapses, the
Inverter starts output from the b030 set value.
The Inverter then decelerates according to b029,
while keeping the output current at the b028 set
value.
• When the frequency matches the voltage, the
Inverter accelerates again, and then output
frequency is restored to the original level.
• If an overcurrent trip occurs under this method,
reduce the b028 set value.
