• Addition: Pipeline filling feature

Parameter F06.58: Pipeline filling frequency
Parameter F06.59: Pipeline filling time
Parameter F06.60: Pipeline filling target pressure

• Adjustment: Modify the sleep condition attainment threshold from 90% to 98%.

• If three or more units are offline, including both the primary and secondary units, the standby unit will still be able to go online. In previous versions, the standby unit would not automatically go online.

F05.65 represents the time for setting a timed malfunction. 
F05.66 represents the unit setting, where setting it to 1 corresponds to seconds (s), and setting it to 0 corresponds to hours. 
F05.67 represents the automatic reset time for E070 faults, measured in seconds (s). 
F05.68 represents the automatic reset time for E030 faults, also measured in seconds (s).

• Adjustment: The maximum value supported for parameter F05.20 is 6000.0 seconds.
• Addition: Parameter F05.65 introduces a timed fault E070, where the most significant bit represents the unit of measurement. If the most significant bit is 0, the unit is hours; if it is 1, the unit is seconds. The maximum supported value is 2000 hours or 2000 seconds.
• Parameter F05.66 sets the automatic reset time for fault E070, with the current upper limit set at 100 seconds.

Fault F05.67 has a preset recovery time of E030, which is currently set to a default value of 36000 seconds. However, there is a bug in the system causing the frequency converter to fail to start after the fault is recovered, and manual mode is also unable to initiate.

IP20_60521_1

2023-01-13

The functionality of fault code F05.64 has been disabled due to error code E060.

• Rectify the bug that prevents the device from entering sleep mode when the wake-up delay time F09.51 is not set to 0.

IP65_60324_2

2022-12-29

F17.73 is synchronized with the standby indicator light.

2023-01-01 BUG

The default value for the wake-up delay time F09.51 upon factory settings is 0.0. If it is modified to any other numerical value, the device will be unable to wake up after entering sleep mode.

IP65_60324_1

2022-12-25

• 与IP20_60519软件同步更新，暂未将F17.73与standby指示灯同步

IP20_60519_2

2022-12-14

• We have not yet synchronized the F17.73 with the standby indicator light, as per the IP20_60519 software update.

IP20_60517_3

2022-12-09

• Modify parameter F17.73 to synchronize with the status of the standby indicator light.

IP20_60517_2

2022-12-07

• Change the feedback pressure in manual mode to real-time updating.

IP20_60517_1、IP_65_60323_1

2022-12-06

• Bug fix: After entering sleep mode, one of the slave machines fails to start when switching to manual mode.

IP65_60317

2022-07-08

• I have primarily added F05.62, the shutdown handling mode; 0: remains the same as before, 1: avoids communication congestion, 2: multiple shutdown commands.

Number of shutdown command transmissions (valid when F05.62=2).

• Rectify the machinery function: After entering sleep mode, the machinery will be restarted. The time-based machinery has been enhanced to execute in seconds. When selecting seconds, it is possible to configure F00.28=2 to clear any portion that is less than one hour.
• Enable frequency setting for the offload detection function. Parameter F06.57 sets the frequency limitation (F05.12 sets the function switch, F05.13 sets the detection current percentage, and F05.14 sets the detection time).

F05.61: Set the maximum number of activated water pumps in automatic mode.
F26.07: Modify the priority for starting inverters with lower stack numbers to 0, inverters with shorter running times to 1, and sequentially rotate based on Modbus addresses to 2.
F26.29: When set to 2, it is possible to configure the manual or automatic mode through the upper-level computer (communication address 2005H, where data 0 represents automatic mode, 1 represents manual mode, with power loss memory).

• Send external fault command with data 9 to communication address 1000H, resulting in the variable frequency drive (VFD) entering a free stop state (sending this command to the host will stop the main pump, auxiliary pump, and secondary pump).

PS：

There are a few issues with this version, which have been updated in later versions

IP20_60501

• This version lacks an automatic external fault reset feature, which would enable the automatic switching of the host when there is a terminal input external fault causing a shutdown.
