• OL1 (Motor Overload)
• OL3 (Overtorque)
• OL2 (Drive Overload)
• OV (DC Bus Overvoltage)
• GF (Ground Fault)
• UV1 (DC Bus Undervoltage)
• OH1 (Overheat)
In order for auto restart after a UV1 fault, Momentary Power Loss Ride-thru must be enabled (L2-01 = "1: PwrL Ride Thru t," or "2:
CPU Power Active"). Setting H2-01 or H2-02 equal to "1E" configures a digital output as "Restart Enabled" to signal if an impending
auto restart is possible.
