The setting of parameter L5-02 determines whether the fault output (MA-MB) will be closed during an auto restart attempt.
The setting of L5-02 can be important when interfacing the Drive with other equipment.
The following faults will allow the Auto Restart function to initiate:
•
OC (Overcurrent)
•
LF (Output Open Phase)
•
PF (Input Phase Loss)
•
PUF (DC Bus Fuse)
•
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.
