4-95
14-28 Forced Run Command
Range 0.00~(the value of 00-12)
 This function is enabled when PID mode (10-03) is selected. Pump will not depend on the feedback
to make any PID output adjustment and runs the frequency of 00-05 (Frequency command) when
multi-function digital input (S1~S6) is set to 16 (PID control disable).
。
 And when the other digital input is set to 57(forced frequency run), inverter sets the frequency to run
depending on the parameter 14-28 (forced run command). If PID function disable is removed, the
inverter is controlled by PID.
14-29 Switching Time of Water Pressure Detection
Range 【0~240】Hr
 If function of multiple pumps in parallel is enabled, the switching way is MasterSlave1
Slave2Slave3  Master  … and the switching time is set via parameter 14-72.
14-30 Detection Time of Multiple Pumps in Parallel Running Start
Range 【0~30】s
 When parameter 14-31 is set to 1 or 3, detection time of multiple pumps in parallel running start is
enabled. If water pressure can not reach the error range of constant pressure and water flow time is
over the detection time (14-30), Master will inform Slave of running start.
14-31 Synchronous Selection of Multiple Pumps in Parallel
Range
0: Disable
1: Pressure Setting Run/Stop
2: Pressure Setting
3: Run/Stop
 When 14-31=0: Disabled
 When 14-31=1: Set 14-01 to 1, Pressure setting and Run/ Stop command are modified by master
and Slave follows Master’s command. Ru n /Stop command from Slave can be regarded as the
emergency stop command with the highest priority.
 When 14-31=2: Pressure setting is modified by Master and Slave follows Master’s command to
update synchronously.
 When 14-31=3: Run/ Stop command is set by Master and Slave follows Master’s command.
Run/Stop command from Slave can be regarded as the emergency stop command with the
highest priority.
Note:
1. When Master modifies the pressure setting, it requires pressing ENTER key to modify the pressure
setting of Slave.
2. When the switching time of multiple pumps in parallel (14-29) changes and reconnection, it will
recount the time.
