TM.iQp.07 iQpump Controller Programming Manual

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 iQpump 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.
