6.2. Control source selection
The selected "control source" serves to provide the inverter with its start, stop, and
reversal commands.
Possible control sources are:
• Digital inputs
• Keypad
• Network
Irrespective of the control source selection, stop commands are always active from
each source connected! If, for instance, the network control is active and a keypad is
connected for diagnostic purposes, the motor is also stopped if the keypad key
is
pressed.
Exception: In the jog operation, a stop command has no impact.
