Base Block
This feature is used to remove the output of the inverter while operating but maintaining
the operating status of a run relay. When a digital input set to 33 (Base Block) is activated
during operation, the output is blocked and the motor will run freely. The output being
blocked by the base block feature does not have effect on the relay and will be recognized
as being in operation even if there is no inverter output. When the base block signal is de-
activated, speed search operation will start with the value set in Cn.72~75 even if the Cn.71
speed search operation selection parameter is not activated.

Define
Set a multi-function (digital) relay terminal to 14 (Run).
When the run command is applied, the inverter will accelerate up to
the reference frequency. When the base block signal is applied during
acceleration or constant speed operation, the inverter will block the
output immediately and motor will free-run. When the base block
signal is de-activated, the inverter will accelerate as a speed search
operation until it reaches the reference frequency, without receiving a
specific reset command.
"bb" will be displayed on the keypad during the base block
operation. De-activating the base block input will reset the inverter
automatically and the base block will not be recorded in the trip
history.
