Chapter 6 - Parameter Description [APP]
6-72
Steps to use MMC operation
A. Set MMC in APP-01
B. Set Process PI to Yes in APP-02
C. Set Pre PID operation enable/disable
Related Parameter: APP-74, 75, 76 and 77.
a. Used for trial operation to check such as pipe
damage before operation.
b. Used to know the starting set point before PID
operation
D. Set PID set point value input method in APP-04
a. Keypad, V1, I …
b. Set target value
E. Set PID Feedback input method in APP-06
a. Set according to sensor used.
b. Analog input (4~20mA, 0~10V …)
c. Select Units of Process Variable (PSI, percent, etc)
in I/O-86.
d. Scale Feedback with I/O-87 and APP-31, 32 or 33.
e. Check whether the setting performs well.
i. Pre-operation is needed.
ii. Checks whether output to feedback value is
generated.
F. Set Multi-motor driving sequence in APP-66
a. Modes EXCH_NONE and AUX_EXCH: Main
motor and Aux motors used
i. Available motor: Main motor 1 + Aux motors 4
(max).
b. MAIN_EXCH Mode: Exchange of Main/Aux
motors to drive output
ii. Available motor: Aux motors 4 (max).
G. Set the number of Aux motors in APP-43
H. Set the starting Aux motor in APP-41
I. Set the start freq of Aux motors in APP-44~47
J. Set the stop freq of Aux motors in APP-51~54
K. Start operation.
Related MMC functions and parameters
A. Energy-saving under light load
Sleep, Wake up APP-63, 64, 65.
B. To easily and effectively use Process PID
operation, Pre PID APP-74, 75, 76, 77.
C. To divide the load to the motor equally
Auto Change APP-66, 67, 68.
D. To associate other conditions with Aux motor
operation, INTERLOCK APP-69.
E. Adjusting Aux motor ON/OFF condition and
output (pressure, air/wind volume) variation
Aux Start Diff APP-71
Aux Stop Diff APP-72.
F. To change response characteristics
PI Control APP-03, 07, 08 and 09.
APP-63: Sleep Delay Time
APP-64: Sleep Frequency
APP-65: Wake-Up Level
The Sleep function is initiated when output demand is
low. The drive stops the motor when the frequency
output dips below the Sleep Frequency (APP-64) for
the duration of the Sleep Delay Time (APP-63).
While in the sleep state, the drive keeps monitoring
the process (feedback) and initiates the Wake-Up
function when the feedback has decreased below the
Wake-Up level (APP-65).
