Protection
Features
Ground Fault Protected from damage
Short Circuit Protected from damage
Motor Overload Programmable inverse time overload trip
Torque Limit All four quadrants individually programmable
Overvoltage Short voltage peaks are bridged; an error is triggered if an ov-
ervoltage lasts for longer than 500 ms
Undervoltage Short voltage dips are bridged; a defined “Restart” is performed
if an undervoltage lasts for longer than 200 ms
Over Temperature Protected from damage, warning display
MOL Input Terminal Programmable for N.C. or N.O. contacts
