■
o2-05 Frequency Reference Setting Method Selection
The factory default setting of the Frequency Reference Setting Method parameter (o2-05 = “1: Enabled”) dictates that when setting a
Speed Command via the digital operator (“Hand” mode), it is not necessary to press the DATA/ENTER key before the iQpump drive will
begin to accelerate or decelerate to the new set speed. This is referred to as MOP (Motor Operated Potentiometer) type functionality.
When o2-05 = “1: Enabled,” the speed command is stored to memory 5 seconds after the INCREASE or DECREASE keys are released.
When o2-05 = “0: Disabled,” the digital operator INCREASE and DECREASE keys will change the speed command but the iQpump
drive will not accelerate or decelerate to the new speed command until the DATA/ENTER key is pressed. In order to change the Speed
Command in the HAND mode, U1-01 must be the top monitor and then the ENTER key must be pressed in order to access the Speed
Command function. This in not to be confused with pressing the ENTER key in order to achieve a change in speed using the INCREASE
and DECREASE keys, which is the subject of parameter o2-05.
■
o2-06 Operation Selection when Digital Operator is Disconnected
Leaving o2-06 enabled will cause the iQpump drive to fault, when the digital operator is removed, even if it’s not outputting to the motor.
The reset key on the digital operator will need to be pressed after reconnecting the digital operator to reset the fault and continue normal
operation.
If o2-06 = “0: Disabled” then the iQpump drive will not fault if the digital operator is disconnected, but the iQpump drive will
discontinue motor operation. If full iQpump drive operation is required while the digital operator is removed set o2-06 = “0: Disabled”
and o2-15 = “0: Disabled” (Hand Key Function). If both o2-06 and o2-15 are disabled then the digital operator can be disconnected
without disturbing iQpump drive operation.

Setting Range: 0 to 65535 Hours
Factory Default: 0 Hours
■
o2-08 Cumulative Operation Time Selection
The iQpump drive features an Elapsed Timer monitor that records in units of hours. The Elapsed Timer monitor is U1-13. Parameter o2-
08 programs this function to either accumulate elapsed hours based on time the iQpump drive is powered (o2-08 = “0: Power-On Time”)
or time the iQpump drive is running (o2-08 = “1: Running Time”). The iQpump drive is considered “running” anytime there is an active
run command or when the iQpump drive is outputting voltage (i.e. including during deceleration).
Parameter o2-07 allows manual adjustment of the Elapsed Timer, primarily to accommodate maintenance or control board replacement
in the event of damage. To reset the Elapsed Timer back to zero, set o2-07 = 0.
