ABB ACS320 User Manual

Actual signals and parameters 185
 Group 17: Override
This group defines the source for the override activation signal, the override speed/
frequency and pass code and how the override is enabled and disabled.
When override DI is activated, the drive stops and then accelerates to the preset
speed or frequency. When the DI is deactivated the drive stops and reboots. If the
start command, run enable and start enables are active in the AUTO mode the drive
starts automatically and continues normally after override mode. In the HAND mode
the drive returns to OFF mode.
When override is active:
• Drive runs at preset speed.
• Drive ignores all keypad commands.
• Drive ignores all commands from communication links.
• Drive ignores all digital inputs except override activation/deactivation, RUN
ENABLE and START ENABLE.
• Drive displays alarm message 2020 OVERRIDE.
