Starting patterns
The inverter makes its frequency shift in accordance with the starting patterns shown below to
search the speed and rotation direction of the idling motor. When harmonization is complete
between the motor speed (including its rotation direction) and the inverter output frequency, the
frequency shift by auto search operation is terminated.
* Only when the auto search has not succeeded at the first trial,
the starting from the opposite direction is attempted.
Starting Patterns
Auto search operation is attempted using one of the patterns shown above. If not
succeeded, it will be tried again. If seven consecutive retries failed, the inverter will
issue
0c3 alarm and stop.
H11
Deceleration Mode
H11 specifies the mode of deceleration when a run command is turned OFF.
Data for H11 Function
0
Normal deceleration
The inverter decelerates and stops the motor according to deceleration
commands specified by H07 (Acceleration/deceleration pattern) and F08
(Deceleration time 1).
1
Coast-to-stop
The inverter immediately shuts down its output. The motor stops according to the
inertia of motor and load machinery and their kinetic energy losses.
When the reference frequency is low, the inverter decelerates the motor according to
the deceleration commands even if H11 = 1 (Coast-to-stop).
