item Function description
Display function
Digital display Display current run status parameter and set parameter
Status indicator light
A, Hz, V
unit for relevant current digital displayed physical parameter(for
current is A, for voltage is V, for frequency is Hz)
MOD
This indicator light is lit in nonsupervision status and extinguished
if no key pressed for a minute, then come back to supervision status
ALM
Alarm indicator light, indicate that the inverter is in over current or
over voltage suppressing status or failure alarm status currently
FWD
Forward run indicator light，indicate that the
inverter output forward phase order and the
connected motor rotate in forward direction
The inverter work in
DC brake status if
FWD, REV
indicator light is lit
at the same time
REV
reverse run indicator light, indicate that the
inverter output reverse phase order and the
connected motor rotate in reverse direction
4.2.4 Key board display status
EDS1000 keypad display status is classified as waiting status parameter display,
function code parameter editing status display, malfunction alarm status display, run
status parameter display in total 4 kinds of status. LED indicator light will all be lit
after the inverter electrified, and digital display LED will display character“-EN-”，
then enter into set frequency display. As shown in Fig.4-3 a.
(1) waiting parameter display status
The inverter is in waiting status and waiting status supervision parameter is
displayed on keyboard, normally parameter F3.28 decide which status supervision
parameter to be displayed. As shown in Fig.4-3 b，the unit is indicated by rightward
unit indicator light.
To press key，it can display different waiting status supervision
parameter circularly(display 15 kinds of supervision parameter of C group
acquiescently，whether the last 7 kinds of supervision parameter are displayed is
difined by function code F2.11，F2.12, for detail please see C group status
