Coasting to stop
When undervoltage or power failure
occurs, the inverter output is shut off.
1
When undervoltage or a power failure
occurs, the inverter can be decelerated to
a stop.
2
When undervoltage or a power failure occurs,
the inverter can be decelerated to a stop.
If power is restored during a power failure, the
inverter accelerates again.
262
Subtracted
frequency at
deceleration start
0.01Hz 3Hz 0 to 20Hz
Normally operation can be performed with
the initial value unchanged. But adjust the
frequency according to the magnitude of
the load specifications (moment of inertia,
torque).
