2.1.5 Avoid unintended start

While the frequency converter is connected to mains, the motor can be started/stopped using digital commands, bus commands,
references or via the Local Control Panel.
• Disconnect the frequency converter from mains whenever personal safety considerations make it necessary to avoid unin-
tended start.
• To avoid unintended start, always activate the [OFF] key before changing parameters.
• Unless terminal 37 is turned off, an electronic fault, temporary overload, a fault in the mains supply, or lost motor connection
may cause a stopped motor to start.
