Sets the current value when the overload
restriction is activated.
Sets the deceleration time when the
overload restriction is activated. The
value is set to the deceleration time from
the maximum frequency to 0 Hz.
Sets the operation of Overload restriction
2, which operates when the [OLR]
terminal is ON.
The settings are similar to [b021], [b022],
