Figure 20. LM08 Electric motor protection trip curve
Ensure operational motor protection function!
ï‚„ This function must be activated to ensure the motor protection function is
operational!
The trigger level is established from the LM03 Motor Rated Current and LM11 Peak
Motor Current Factor.  Refer to LM11 Peak Motor Current below for additional details.
LM09 Electric Motor Protection Current
Current level for Electric motor protection.
This parameter sets the current threshold in amps above which the Elevator drive
activates the motor overload function, described in LM08 Electric motor protection. This
