4-236
23- 28 Foreced Run Command
Range 【0.00 ~ 599.00】Hz
 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 23-28 (forced run command). If PID function disable is
removed, the inverter is controlled by PID.
23-29 Switching Time of Multiple Pumps in Parallel
Range
【0 ~ 240】hour/min
 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 23-72.
23- 30 Detection Time of Multiple Pumps in Parallel Running Start
Range 【0.0 ~ 30.0】Sec
 When parameter 23-31 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 (23-30), Master will inform Slave of running start.
23- 31 Synchronous Selection of Multiple Pumps in Parallel
Range
【0】: Disable
【1】: Pressure Setting and Run/ Stop
【2】: Pressure Setting
【3】: Run/Stop
 When 23-31=0: Disabled
 When 23-31=1: Set 23-01 to 1, Pressure setting and Run/ Stop command are modified 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.
 When 23-31=2: Pressure setting is modified by Master and Slave follows Master’s command to
update synchronously.
 When 23-31=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 (23-29) changes and reconnection, it will
recount the time.
