The principle of operation of the other parameters is explained in the following diagram and
in the table below.
1)
The inverter automatically acknowledges faults under the following conditions:
• p1210 = 1 or 26: Always.
• p1210 = 4 or 6: If the command to switch-on the motor is available at a digital input or via the
fieldbus (ON/OFF1 = 1).
• p1210 = 14 or 16: Never.
2)
The inverter attempts to automatically switch the motor on under the following conditions:
• p1210 = 1: Never.
• p1210 = 4, 6, 14, 16, or 26: If the command to switch-on the motor is available at a digital input
or via the fieldbus (ON/OFF1 = 1).
3)
If, after a flying restart and magnetization (r0056.4 = 1) no fault occurs within one second, then the
start attempt was successful.
