Dynamic (Regenerative) Braking - To Urgently Stop The Motor - Toshiba TOSVERT VF-P7 Instruction Manual

6.13.4 Dynamic (regenerative) braking - To urgently stop the motor

 ：Dynamic braking mode selection
 ：Dynamic braking resistance
 ：Dynamic braking resistor capacity
・Function
Dynamic braking is used in the following cases:
1) need to stop the motor quickly.
2) The inverter trips because of an over-voltage (OP) during deceleration.
3) Fluctuation of load condition causes a regenerative power even at a constant s
peed such as press machine.

※Default settings vary from model dependent. Refer to 6.13.4-4).
Protection level is defined by (Refer to 6.13.5).
Note 1) While dynamic braking is in operation, "P" blink is displayed at left side of the
monitor. (It is not an error.) The blink starts at achieving (over-voltage
stall protection level / dynamic braking protection level).
Note 2) In the case of oscillating of monitor or taking long time at deceleration, set
(over-voltage stall protection) = .
Note 3) When using braking unit(PB3), set (dynamic braking mode selection) = ,
and (over-voltage stall protection) = .
