Remarks

1

Model

SJ700D-004 to 550LFF3/LFEF3/LFUF3 SJ700D-007 to 1320HFF3/HFEF3/1500HFUF3

2

Added
function

Constant torque/ 
Variable torque   
(CT/VT) selection

Constant torque / Variable
torque mode selectable
(b049)

Newly added parameter b049 to switch between 
Constant torque mode and Variable torque mode.

In case of driving light load application, you can 
choose one power size smaller inverter or one 
frame size smaller inverter.

3

PM motor control
 [ordering production]

Control mode (A044) 

PM motor control (06) is added to the selection in A044 

PM motor control is only available in Variable torque 
mode.  
(note) The model supporting PM motor control is 
ordering production. 

4

PM motor control 
parameters (H101~H134) 

Parameters related to PM motor control are newly added 
(same as WJ200 series)

5

Automatic return 
to the initial display 

Automatic return
to the initial display (b164)

Without operating for 10 minutes, 
the display returns to the initial display automatically. 

6

Data read and 
write

Data Read/Write selection
 (b166)

Selection of enabling or disabling data Read / Write from the 
copy unit WOP for parameter setting protection and security

7

Inverter mode

Inverter mode monitor
 (d060)

Displays currently selected inverter mode, IM motor 
(induction motor) or PM motor mode.(IM mode or PM mode.) 

8

Phase loss 
protection

Phase loss output 
protection (b141,b142)

The inverter detects motor output phase loss

9

Improvement
function

EzSQ

Improvement

Parallel processing of 5 tasks

10

EzSQ starting trigger terminal: changed from FW terminal to 
PRG terminal which can be assigned any of input terminals.

11

Additional function

Always running mode is added to 
selection of starting method for EzSQ. 

12

Command to store changed data into EEPROM (eepwrt command)

13

Command to obtain clock data from WOP (rtcset command)

14

Part of EzSQ program variables (P129 (U29) to P131 (U31)) 
are automatically stored at power down (only when A017 is 
other than 00)

15

WOP operator 
[Option] 

Full compatibility with the copy unit WOP(5 line display)

16

Real time clock function is available. 

17

RS485 

Communication speed 
is improved. 

2400/4800/9600/19.2k/38.4k/57.6k/76.8k/115.2k bps 

18

Modbus RTU

Maximum data length is expanded. 
03h (Read holding register) 10h (Write in holding resisters) 

4 registers (8 byte) to 16 registers (32 byte)

19

Command to write into/read from multiple holding registers 
is added (17h: Write/Read multiple holding registers)

Read and Write 16 registers (32 byte)

20

Broadcast communication function is added. 

21

EEPROM storing mode is added. 

22

Initializing 

Initializing method 

Parameter setting (b180=01) triggers initialization

Initialization method of SJ700-2  is also valid.

23

Initializing of EzSQ 

Parameter b084 range is expanded. 

24

Initial value 

b037=00 (Full access) 

25

Selection of
initial display

Selection of initial display is expanded
(all monitoring parameters, frequency command F001 (WOP monitor B)

26

Others

Warnings

Warnings are organized. 

47 warnings to 31 warnings

27

Run command in
case of warnings

At occurrence of warning, the inverter does not accept Run command.
