(Comparison between SJ700-2 and SJ700D-3)
Enhanced function, added parameters, etc.
Constant torque / Variable
Newly added parameter b049 to switch between
torque mode selectable
Constant torque mode and Variable torque mode.
(b049)
Control mode (A044) PM motor control (06) is added to the selection in A044
PM motor control Parameters related to PM motor control are newly added
parameters (H101~H134) (same as WJ200 series)
Automatic return Without operating for 10 minutes,
to the initial display (b164) the display returns to the initial display automatically.
Data Read/Write selection Selection of enabling or disabling data Read / Write from the
(b166) copy unit WOP for parameter setting protection and security
Inverter mode monitor Displays currently selected inverter mode, IM motor
(d060) (induction motor) or PM motor mode.(IM mode or PM mode.)
Phase loss output
The inverter detects motor output phase loss
protection (b141,b142)
Parallel processing of 5 tasks
Improvement
EzSQ starting trigger terminal: changed from FW terminal to
PRG terminal which can be assigned any of input terminals.
Always running mode is added to
selection of starting method for EzSQ.
Command to store changed data into EEPROM (eepwrt command)
Additional function
Command to obtain clock data from WOP (rtcset command)
Part of EzSQ program variables (P129 (U29) to P131 (U31))
are automatically stored at power down (only when A017 is
other than 00)
Full compatibility with the copy unit WOP(5 line display)
Real time clock function is available.
Communication speed
2400/4800/9600/19.2k/38.4k/57.6k/76.8k/115.2k bps
is improved.
Maximum data length is expanded.
03h (Read holding register) 10h (Write in holding resisters)
Command to write into/read from multiple holding registers
Modbus RTU
is added (17h: Write/Read multiple holding registers)
Broadcast communication function is added.
EEPROM storing mode is added.
Initializing method Parameter setting (b180=01) triggers initialization
Initializing of EzSQ Parameter b084 range is expanded.
Initial value b037=00 (Full access)
Selection of initial display is expanded
(all monitoring parameters, frequency command F001 (WOP monitor B)
Warnings are organized.
At occurrence of warning, the inverter does not accept Run command.
PM
In case of driving light load application, you can
choose one power size smaller inverter or one
frame size smaller inverter.
PM motor control is only available in Variable torque
mode.
(note) The model supporting PM motor control is
ordering production.
4 registers (8 byte) to 16 registers (32 byte)
Read and Write 16 registers (32 byte)
Initialization method of SJ700-2 is also valid.
