DANGER
UNINTENDED EQUIPMENT OPERATION
•The automatic restart can only be used on machines or installations which do not pose any danger to either
personnel or equipment.
• If the automatic restart is activated, R1 will only indicate a fault has been detected once the time-out period for
the restart sequence has expired.
• The equipment must be used in compliance with national and regional safety regulations.
Failure to follow these instructions will result in death or serious injury.

YES
This function defines drive behavior upon detection of a fault.
If validated, this function allows an automatic restart of the drive when the cause of the detected fault has
disappeared and the other operating conditions permit the restart.
v Function inactive
v Automatic restart, after locking on a detected fault, if the cause has disappeared and the other operating
conditions permit the restart. The restart is performed by a series of automatic attempts separated by
increasingly longer waiting periods: 1 s, 5 s, 10 s, then 1 minute for the following attempts.
The drive status relay remains activated if this function is active. The speed reference and the operating
direction must be maintained.
Use 2-wire control (Type of control tCC page 48 = 2C and 2 wire type control tCt page 51 = LEL).
If the restart has not taken place once the Max. automatic restart time tAr has elapsed, the procedure
is aborted and the drive remains locked until it is turned off and then on again.
The detected faults, which permit this function, are listed on page 110:
