VLT AutomationDrive FC 301/302
Programming Guide
The following events are logged:
• W200 - Emergency mode.
• W201 - Emerg. M mode was act. (deactivated).
• W202 - Emerg. M limits exceeded covered by the activated critical alarm number.
• (W280) - Emcy M service warning - service is needed.
• (W281) - Emcy OPR unexpected - emergency mode does not work as expected.
All alarms are logged as usual, and critical emergency mode alarms are logged in the emergency mode log in parameter group 18-1*
Emergency Mode Log.
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.
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.
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.
