Conditions for PI_PROCESS output: C = 0: Const PI,
C = 1: PI_PROCESS-B >= PI_PROCESS-OUT >= 0,
C = 2: PI_PROCESS-B >= PI_PROCESS-OUT >= -(PI_PROCESS-B),
P gain = A/100, I gain = 1/(Bx Loop Time),
If there is an error with PI settings, output -1.
26 PI_PROCESS
A is an input error, B is an output limit, C is the value of Const PI output.
Range of C is 0–32,767.
27 UPCOUNT
Upcounts the pulses and then output the value- UPCOUNT(A, B, C).
After receiving a trigger input (A), outputs are upcounted by C conditions. If
the B inputs is 1, do not operate and display 0. If the B inputs is 0, operate.
If the C parameter is 0, upcount when the input at A changes from 0 to 1.
If the C parameter is 1, upcount when the input at A is changed from 1 to 0.
If the C parameter is 2, upcount whenever the input at A changes.
Output range is: 0–32767
28 DOWNCOUNT
Downcounts the pulses and then output the value- DOWNCOUNT(A, B, C).
After receiving a trigger input (A), outputs are downcounted by C
conditions. If the B input is 1, do not operate and display the initial value of
C. If the B input is 0, operate.
Downcounts when the A parameter changes from 0 to 1.
The Pl process block (Pl_PROCESS Block) must be used after the PI control block (PI_CONTROL Block)
for proper Pl control operation. Pl control operation cannot be performed if there is another block
between the two blocks, or if the blocks are placed in an incorrect order.
User sequence features work only with code version 1.00, IO S/W version 0.11, and keypad S/W version
1.07 or higher versions.
4.24 Fire Mode Operation
This function is used to allow the inverter to ignore minor faults during emergency situations, such
as fire, and provides continuous operation to fire pumps.
When turned on, Fire mode forces the inverter to ignore all minor fault trips and repeat a Reset
and Restart for major fault trips, regardless of the restart trial count limit. The retry delay time set at
PR. 10 (Retry Delay) still applies while the inverter performs a Reset and Restart.
