B.8 L: Protection Function
L parameters provide protection to the drive and motor, including control during momentary power loss, Stall Prevention,
frequency detection, fault restarts, overtorque detection, and other types of hardware protection.

The drive may not be able to provide protection when using
multiple motors, even if overload is enabled in L1-01. Set L1-01
to 0 and install separate thermal relays to each motor.
