previous speed command can be reset to the frequency reference lower limit automatically by closing either the UP or Down input
without having a Run command active.
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).
■
Function: Fast Stop N.O. (Setting: 15)
■ Function: Fast Stop N.C. (Setting: 17)
The Fast Stop function operates much like an emergency stop input to the drive. While in the Run mode, if a Fast Stop is input to the
iQpump drive (CLOSED for H1-0x = 15 or OPEN for H1-0x = 17), the iQpump drive will decelerate to a stop with the deceleration time
determined by C1-09 (Fast Stop Time). The Run command can remain closed during the Fast Stop operation. The iQpump drive will not
run, from either the terminals or the digital operator, while the Fast Stop is being input to the drive. To restart the drive, the Fast Stop input
must be removed and the Run command must be cycled.
