brownout (P1211 disabled):

 

 

 

For these settings it is fundamental that

 

 

 

the drive only restarts if it has been in a

 

 

 

RUN state at the time of the fault

 

 

 

(F0003). The inverter will acknowledge

 

 

 

the fault and will restart the drive after a

 

 

 

blackout or brownwout. It is necessary

 

 

 

that the ON command is wired via

 

 

 

digital input (DIN).

 

 

 

P1210 = 5, Restart after blackout or fault

 

 

 

(P1211 disabled):

 

 

 

The inverter will acknowledge the faults

 

 

 

(F0003 etc.) at power on after blackout

 

 

 

and will restart the drive. It is necessary

 

 

 

that the ON command is wired via digital

 

 

 

input (DIN).

 

 

 

P1210 = 6, Restart after supply power

 

 

 

brown/blackout or fault (P1211 disabled):

 

 

 

The inverter will acknowledge the faults

 

 

 

(F0003 etc.) at power on after blackout or

 

 

 

brownout and will restart the drive. It is

 

 

 

necessary that the ON command is wired

 

 

 

via digital input (DIN). Setting 6 causes

 

 

 

the motor to restart immediately.

 

 

 

P1210 = 7, Restart after supply power

 

 

 

brown/blackout or fault (P1211

 

 

 

enabled):

 

 

 

This setting is for use where an external

 

 

 

bypass system or process is interlocked

 

 

 

with a relay that is set to

 

 

 

P0731/P0732=52.3 (fault). The inverter

 

 

 

functions the same as P1210=6 (trip on

 

 

 

brownout, blackout or fault) but uses

 

 

 

P1211 and only sets the fault bit

 

 

 

P0731/P0732=52.3 when the specified

 

 

 

number of restarts defined in P1211 has

 

 

 

expired. If no trip occurs after 2 hours,

 

 

 

the fault counter is reset.

 

 

 

 

 

 

NOTES:

1.Auto restart requires a constant ON command (such as via a digital input).

2.P1200 flying start must be used in cases where the motor may still be turning, such as after a brief input power break, or can be driven by the load.

3.A supply power brownout is when the power is interrupted and reapplied before the operator panel display has gone dark. It is a very short supply power break where the DC link has not fully collapsed.

4.A supply power blackout is when the operator panel display has gone dark before the power is reapplied. It is a long supply power break where the DC link has fully collapsed.
