Functions
8.11 Emergency mode
• Motor heating
• Operation at a rated operational voltage U
The 3RW55 soft starter's intrinsic device protection remains active when an active emergency
run (failure of a power semiconductor) is active. This ensures that no consequential damage
arises due to use of the "Emergency run" function if the motor and the plant continue to be
operated.
Application
• Avoiding unwanted plant standstills and failures
Validity
This function is not available for the 3RW55 Failsafe soft starter.
Requirements
• 3RW55 soft starter from firmware version V2.1
• Ex operation not active
Setting options
• 3RW5 HMI High Feature
Menu: "Parameters > Soft Starter > Emergency mode > Emergency run"
