YASKAWA TM.iQp.02 iQpump Drive Programming Manual
Description
Sets the level used for multiplex pumping operation. Parameter is
active when P3-01 = 0 or P3-01 = 2 is selected.
P3-01=0: When the output frequency falls below the level
programmed in P3-09 for a time specified in P3-06 and a total of 2
pumps are running, the last pump (Pump 2) that was brought online
will be shutdown by means of a multi-function digital output opening
(H2-XX = 40, 41).
P3-01=1: Not Used.
P3-01=2: When the output frequency falls below the level
programmed in P3-09 and a total of 2 pumps are running and the delta
feedback (feedback minus setpoint) has exceeded the level
programmed in P3-05 for a time specified in P3-06, the last pump
(Pump 2) that was brought online will be shutdown by means of a
multi-function digital output opening (H2-XX = 40, 41).
Sets the level used for multiplex pumping operation. Parameter is
active when P3-01 = 0 or P3-01 = 2 is selected.
PE-01=0: When the output frequency falls below the level
programmed in P3-10 for a time specified in P3-06 and a total of 3
pumps are running, the last pump (Pump 3) that was brought online
will be shutdown by means of a multi-function digital output opening
(H2-XX = 40, 41).
P3-01=1: Not Used.
P3-01=2: When the output frequency falls below the level
programmed in P3-10 and a total of 3pumps are running and the delta
feedback (feedback minus setpoint) has exceeded the level
programmed in P3-05 for a time specified in P3-06, the last pump
(Pump 3) that was brought online will be shutdown by means of a
multi-function digital output opening (H2-XX = 40, 41).
Sets the time used to stabilize system when a pump is added (brought
online) or shutdown during multiplex operation. When a pump is
added, the stabilize timer temporarily disables the lead/lag
functionality for the programmed time to prevent pump cycling.
Note: This function only active in the multiplex mode when P1-01 is
greater than 0.
During the stabilization time, the pump protection and lead-lag control
is suspended.
Sets the level when the acceleration and deceleration times change over
to the values programmed in C1-05 and C1-06 respectively. This
function will activate when the difference between the delta setpoint
and feedback are within the level programmed in P3-12. This function
is used to improve the pump regulation.A value of 0 disables this
function.
Sets the level when the setpoint will be adjusted to compensate for the
friction losses. This function will activate when the output frequency
rises above the level programmed in P3-13. The maximum
compensation at maximum output frequency (E1-04) is specified by
maximum setpoint frequency (P2-10).
Note: This function is only active in simplex mode when P1-01 = 0.
Sets the maximum setpoint friction compensation at maximum output
frequency (E1-04). This function is a linear calculation with P3-13 as
its starting frequency.
Example: P3-13 = 30.0 Hz, P3-14 = 10.0 PSI, output frequency = 45.0
Hz and maximum frequency = 60.0 Hz
Setpoint Increase = (45-30 Hz) x 10 PSI / (60 Hz – 30 Hz) ≥ 5.0PSI
Note: This function is only active in simplex mode when P1-01 = 0.
