Table 7- 44 Setting the automatic restart

Parameter Explanation

Automatic restart mode (factory setting: 0) p1210

14:

16:

26:

Disable automatic restart

Acknowledge all faults without restarting

Restart after power failure without further restart attempts

Restart after fault with further restart attempts

Restart after power failure after manual fault acknowledgement

Restart after fault after manual fault acknowledgement

Acknowledgement of all faults and restart with ON command

p1211 Automatic restart start attempts (factory setting: 3)

This parameter is only effective for the settings p1210 = 4, 6, 14, 16, 26.

You define the maximum number of start attempts using p1211. After each successful

fault acknowledgement, the inverter decrements its internal counter of start attempts by

For p1211 = n, up to n + 1 start attempts are made. Fault F07320 is output after n + 1

unsuccessful start attempts.

The inverter sets the start attempt counter back again to the value of p1211, if one of

the following conditions is fulfilled:

• After a successful start attempt, the time in p1213[1] has expired.

• After fault F07320, withdraw the ON command and acknowledge the fault.

• You change the start value p1211 or the mode p1210.

p1212 Automatic restart wait time start attempt (factory setting: 1.0 s)

This parameter is only effective for the settings p1210 = 4, 6, 26.

Examples for setting this parameter:

1. After a power failure, a certain time must elapse before the motor can be switched-

on, e.g. because other machine components are not immediately ready. In this case,

set p1212 longer than the time, after which all of the fault causes have been

removed.

2. In operation, the inverter develops a fault condition. The lower you select p1212,

then the sooner the inverter attempts to switch-on the motor again.
