Function: Reset Cmd Active (Setting: 11)
A Reset Cmd Active digital output will close to signal that a Fault reset is being attempted from terminals or Serial Com.
Function: Timer Output (Setting: 12)
This Timer function, that is built into the Drive, is independent of the rest of the iQpump drive operation, i.e. there is no requirement for
a Run command for the timer to operate. A Timer digital output will close b4-01 seconds after a digital input configured as Timer Input
(H1-0x = 18) closes and remains closed. The Timer digital output will remain closed for b4-02 seconds after the Timer digital input opens
and remains open.
Refer to the descriptions of parameters b4-01 and b4-02 for a timing chart of the Timer function.
Function: Trq Det 1 N.C. (Setting: 17)
The Trq Det 1 function ties a digital output to the overtorque/undertorque sensing capabilities of the Drive. If a digital output is
configured as Trq Det 1 N.C., whenever the output current exceeds the level of L6-02 for at least the length of time set in L6-03, the
digital output will open.
The torque detection function has a built-in hysteresis of 10% of the iQpump drive rated output current.

Function: Reverse Dir (Setting: 1A)
The Reverse Dir digital output will close whenever the iQpump drive is turning the motor in the direction that corresponds to the reverse
direction (CW or CCW). The Reverse Dir digital output will remain closed during deceleration when the rotation is in the reverse
direction.

Function: Restart Enabled (Setting: 1E)
Depending on the setting of parameter L5-01, the iQpump drive may be configured to automatically attempt to restart itself after certain
faults. The Restart Enabled output will be closed once the restarts begin and will remain closed until a successful restart is accomplished
or the number of Auto Restart attempts as specified by L5-01 is reached.
A timing diagram for the Auto Restart function is contained in the parameter L5-01 description.
