N O T I C E
During emergency-mode operation, all stop commands to the drive are ignored, including coast/coast inverse and external inter-
lock. The keypad is also locked during emergency mode to prevent user interference during operation of the safety system. How-
ever, if Safe Torque Off is available in the drive, this function is still active.
N O T I C E
Emergency mode has a special live zero function for handling lost analog signal inputs used for emergency mode setpoint/feed-
back, for example, for handling a burnt cable. How emergency mode should continue in these live zero situations is configured in
parameter 6-02 Emergency Mode Live Zero Timeout Function. If live zero is activated, Emergency mode not working as expected is
activated so that a redundant system can take over or a setup change can be activated. A warning for live zero has a higher
priority than the warning Emergency mode and will replace that information in the display.
N O T I C E
If setting the command [11] Start Reversing on a digital input terminal in parameter 5-10 Terminal 18 Digital Input, the drive under-
stands this as a reversing command.
