NOTE
• The stop selection setting is disabled when the following functions are operating.
Power failure stop function (Pr.261)
PU stop (Pr.75)
Deceleration stop due to a communication error (Pr.502)
Offline auto tuning (with motor rotation)
• When Pr.250 ≠ "9999 or 8888", acceleration/deceleration is performed in accordance to the frequency command until the
output is shut off by turning OFF the start signal.
• When the restart signal is turned ON during the motor coasting, the operation is resumed from Pr.13 Starting frequency.

5.13.11 Regenerative brake selection and DC feeding
mode
• For the operation with frequent starts and stops, the regenerative power can be consumed by using the optional brake unit
(FR-BU2, BU, or FR-BU).
• The power regeneration common converter (FR-CV) or power regeneration converter (MT-RC) is used for the continuous
operation during regenerative driving. The high power factor converter (FR-HC2) can be used also to reduce harmonics,
improve power factor, and operate continuously during regenerative driving.
• It is possible to choose between the DC feeding mode 1, which will operate with DC power supply (terminals P and N), and
DC feeding mode 2, which will normally operate in AC power supply (terminals R, S, and T) and operate in DC power
supply (terminal P and N), such as batteries, at the time of power failure.
• While the power is supplied only to the control circuit, the reset operation when the power is supplied to the main circuit
can be selected.
