3.Main Feature
Easy Handling
Incoming voltage is indicated orderly while a motor is stopped
To give a guarantee to exclusive operator:Password Input
To realize convenient and various data input
•Loader: DSP-VIP-PL
•Display Meter: DSP-VIP-PM
•Note Book PC: DSP-VIP-PL,VIP-PM
Main/Sub/Cab Menu:Three devided menu group according to usage and the frequency of data input
•Main menu:Data input frequency is rather higher
•Sub menu:Ratherly common application for all kind of motor
•Cab (calibration) menu :adjustable for indicating value within narrow range
(
±
12.7%) /This menu is appeared when "SET" key is pressed for 5 sec or more
and disappeared right after pressing again.
Beautiful inside lighting by every touch button:Easy handling in dark space of the panel.
To Indicate a necessasary information in every 3 sec
•Basic Factor circulating indication:V,I,KW,GR(Ec)/ “OFF” must be set in ”rota” mode
•Basic Factor + PF,Temp,KWH,AWT(Accumulated Working Time)/“ON” must be
set in ”rota” mode/ Possible to fix one of circulated factor or to release:one touch
for CLR Key
•To show load factor(actual/setting)/65% ~ 100%:Line Type/DSP-VIP-PL
,Round Type/DSP-VIP-PM
•
To check preset value during motor run:done by adjusting "SET" & "Mode" key
*Press "SET" key during a motor run,then search mode neccessary to check
, consequently name of mode & preset value is shown alternatively
*not possible to change preset value,only to show preset state.
Duplex Alarm:Higher Alarm,Lower Alarm to OC/Lower Alarm is only possible in case “LinE”
mode is preset for “OFF”
ON-OFF switch/DSP-VIP-PM:to save wiring and labor inside panel
Convenient installation:65Phi circle or rectagular hole(48*96)/DSP-VIP-PM:Display Meter.
To indicate trip number of main contactor:contributing to check a replacing term and
effective maintenance.
To keep a stable operation under frequency variation of Inverter:1Hz ~ 400Hz
To call initialized factory setting value:press test button before power-on,then keep
pressing state for 3 sec after power-on.
Indication for a position of “ON”-"OFF' command to run a motor:in case motor is run or
stopped during the ation by "OFF" or "Auto sensor",a position message like LOP,MCC(Display
meter),rcs(Remote control sensor),out-F(external fault input) and PC that such command
was originated to is appeared in front message window.
Multi-complexed Function
Power type protection relay based on Voltage and Current
To indicate RMS value/Voltage,current:RMS chip adopted in every input/to contribute
to check an exact condition of motor
To act as actual complexed meter:V,I,KW,PF,KWH,Temp
*Voltage Select:110V/220V/380V/440V/480V(110V is secondary voltage of PT)
*Current Meter with CT:0.5A~3600A(Auto Range for decimal point)
*KW Meter:0.1~60000KW(Auto Range)
*Power Factor Meter:
±
0%~100%
*KWH Meter:1KWH~99999999KWH(used "K" unit LED)
*Temperature Meter:0OC ~ 150OC
*Auto Range: to indicate decimal point in conjunction with "K/Test" LED in Loader and DM
To cover a wide current range
*70 Type:0.2A ~70A/0.2A ~ 6A(0.2KW~4.4KW/AC480V) with external CT
*With external CT :0.5~3600A
High sensitive Level and Wide range for ground fault protection:30mA~ 10A
*Standard type/with external ZCT : need to use shield wire for connection between ZCT and
Z1,Z2 terminal of DSP
*Optional type : ZCT embedded
*Alarm to disconnection with ZCT:In case ZCT is disconnected with Z1,Z2 of the
converter after the control power is on,not while operating,the preset process is not
gone ahead anymore as flickering "Ec-ct"/"Off" in "Ec" mode to clear this alarm.
To realize Short,Ground fault protection by instant trip time:0.05 sec
To be acceptable for various rating of ZCT: 200/1.5mA or 200/100mV,selectable in DIP SW
Temperature arising protection of case,winding of motor:sensed by PT100:0C~150OC
*If sensed temperature is greater than preset value, motor can not start
*if PT100 is not connected and the value except "OFF" in "TEP" mode is preset ,alarm
is shown and motor can not start. hence need to preset "OFF" in "TEP" mode to make
a motor start
Various and multiple trip output of Main and Aux relay
*Main/1a(97-98):energized(trip) with an output of C-SC/F-MC/R together
*AUX/1a(07-08):acts same as main trip or one of Shoc/Ec/Uc/AL/Temp/Ec-tE/SS-tr
/Ec-ta/Ec-tb selected in "Au-o" mode
*1a(27-28):trip for Voltage protection,but possible to change into "ALLc"(lower level
alarm) in "Line" mode
To memorize 8 events of the latest trip : to contribute analyzing trouble cause and motor working
condition in conjunction with a number of lighted LED in bar graph to show a order of tripped event.
Main contactor Auto Close:In case a line power is "on" within a preset time(SDDT) after a line power
is "OFF" during a normal operation,main contactor is closed automatically after another preset time
(DOMT)
*Shut Down Delay Time:1~5sec/Adjustable
*Delay On Make Time:0(instant)~25sec/Adjustable by 5 sec unit
*Expression in mode/eg,2-3:in case power is on within 2sec after power-off,motor starts
after 15sec(3 is matched with 15sec) from the instant of power-on
Self-diagonostics:in case of pressing "test" sw in converter or pressing "CLR" key for 3 sec
or more,main trip output is tripped after counting down o-time of definite T-I characteristic or
a time of 550% to "OC" preset value in Inverse T-I Curve ,hence % of bar graph LED shows how
much time is counted down
To have safe operation ,the alarm and the execution not to start motor is done in case as follows:
*PT100 is not connected in case the value is preset in "tEP' mode
*The latest measured temperature is greater than preset value
Remote Control through RS-485/422 digital communication
Various communication module function
* CM44 : 485/422,Modbus/RTU
* MWR-S : 485,Modbus/RTU, 1 month data record/recording interval:50msec/max
Basically 4~20mA output : 20mA for maximum current value among 3 phase
To realize effective system for digital comminication:possible to combine a module simply
if necessary
To response for RS-485/422,Modbus/RTU
To select one of RS 485 and 422 :Simply selectable in DIP SW inside communication module:CM-44
To put easily terminattion resistence in extreme end unit:Simply selectable in DIP SW
inside communication Module
To monitor and input a data by using "samdsp" in the field:Note PC < > Converter of DSP
*PC<RS232>VIP converter:not to need a communication module
*PC<Comm. Module>VIP converter:need 485(Comm. Module)/USB(PC): Protocol
Converter/ DSP-CMB
