Parameterizing the automatic restart
Table 6- 42 Parameterizing the automatic restart
P1210 = Automatic restart mode
0: Automatic restart locked
1: Fault acknowledgment after an ON command; P1211 locked (factory setting)
2: Automatic restart after a power failure; P1211 locked
3: Automatic restart after a line supply undervoltage or fault; P1211 enabled
4: Automatic restart after a line supply undervoltage; P1211 enabled
5: Automatic restart after a power failure and fault; P1211 locked
6: Automatic restart after a line supply undervoltage / failure or fault; P1211 locked
P1211 = Number of automatic restart attempts [minimum 0 ... maximum 10]
P1200 = Starts inverter onto a spinning motor by rapidly changing the output frequency of the
inverter until the actual motor speed has been found. Then, the motor runs up to set-
point using the normal ramp time.
0: Flying start disabled
1: Flying start always active, start --> setpoint
2: Flying start active if power on, fault, OFF2, start --> setp.
3: Flying start active if fault, OFF2, start --> setpoint
4: Flying start always active, only --> setpoint
5: Flying start active if power on, fault, OFF2, only --> setp.
6: Flying start active if fault, OFF2, only --> setpoint
Flying start must be used in cases where the motor may still be turning (e.g. after a
short mains break) or can be driven by the load. Otherwise, overcurrent trips will occur.
Useful for motors with high inertia loads. Settings 1 to 3 search in both directions. Set-
tings 4 to 6 search only in direction of setpoint.
