■ L: Protection Functions
L parameters provide protection to the drive and motor, including control during momentary power loss, Stall Prevention,
frequency detection, fault reset, overtorque detection, torque limits, and other types of hardware protection.
L1: Motor Protection
L2: Undervoltage Detection
No.
(Addr.)
Name Description Setting
