Function
This is the frequency set from the operation
panel.
This is the frequency setting for jogging.
The value can be displayed in units of 0.1
or 10 times as set on B10-5.
The time to reach the max. frequency or
max. speed from 0 is set.
1: Disable = 2: Enable
1: Disable = 2: Enable
Set the boost voltage at 0Hz.
This is automatically adjusted by the
automatic tuning.
Set
the
reduced
voltage
frequency/2.
Set how much to compensate the voltage
drop caused by R1 measured with
automatic tuning.
Set the motor's rated slip.
This is automatically adjusted by the
automatic tuning.
This is automatically adjusted by the
automatic tuning. The optimum boost
amount for outputting the maximum torque
is set.
This is automatically adjusted by the
automatic tuning. When setting manually,
monitor the output voltage and change the
setting in increments of 1% or less.
Set the time to apply the DC brakes.
This is used instead of the DC brake
voltage in the vector mode and PM mode.
This is not adjusted with automatic tuning.
Change is
possible during
operation.
