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.

Important: Be aware that during rapid deceleration the iQpump drive may fault on an over voltage condition. When faulted, the iQpump
drive output shuts off allowing the motor to coast. The result is an uncontrolled motor state. Therefore, be sure to set an acceptable
deceleration time in parameter C1-09 when using the fast stop feature.
Function: Timer Function (Setting: 18)
The Timer Function works independently from the Drive. For Timer operation a digital input must be configured for a Timer Function
start (H1-0x = 18), a digital output must be configured as a Timer Function output (H2-0x = 12), and the Timer Function ON-Delay and
OFF-Delay parameters (b4-01 and b4-02, respectively) must be programmed.
Once the applicable parameter are programmed the Timer Function start digital input must be closed at least as long as the setting of b4-
01 before the Timer Function output will close. The Timer Function input must be open for at least as long as the setting of b4-02 before
the Timer Function output will reopen.

Function: PI Disable (Setting: 19)
When the PI Function has been enabled by b5-01 (PI Mode Selection), it can be indefinitely disabled by closing a digital input configured
as a PI Disable input (H1-0x = 19). When disabled, the iQpump drive operates as a standard drive that does not have PI enabled
Function: Program Lockout (Setting: 1B)
A Program Lockout digital input will allow changing of parameter values when it is open but prevent changing of any iQpump drive
parameter value except the Speed Command when it is closed. Parameter values can be viewed even when a Program Lockout is active.
