52 YASKAWA TM.iQp.02 iQpump Drive Programming Manual
Important: Be sure to set b1-01 = “1: Terminals,” (Auto Setpoint =Terminals) if the MOP function is to be used. If b1-01 = “0:
Operator,” then the MOP is disabled even if it is programmed. The Jog inputs have priority over the MOP function.

Function: Fault Reset (Setting: 14)
Whenever the iQpump drive detects a fault condition, the fault output contact will close and the Drive’s output will shut OFF causing the
motor to coast (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). Once the Run command is
removed, the fault can be reset by either the RESET key on the digital operator or by closing a digital input configured as a Fault Reset
(H1-0x = 14).
