3 CONTROL PANEL
The control panel involves 4 digits 7-segment display and 4 Led-lamps, 8 keys and a potential meter (VR).
It has four possible operation modes: "CTL", "MON", "PAR" and "ALM modes, described below.
3.1 CTL mode
VR input is equivalent to AI3 input.
Push the "CTL/MON" key, will change the keypad operation between "CTL"
and "MON" Mode.
If both "HZ" and "I" Led are blank, it is under "CTL" Mode.
Under "CTL" Mode, user can control the inverter running in either direction
and may modify the desired running speed.
For normal run/stop control, use only the three keys:
FWD
key is used for running the inverter in forward direction.
REV
key is used for running the inverter in reverse direction.
STOP
key is used to stop the inverter.
If Pr.40=3 or 8, the running frequency shall be modified by keypad, then these
keys are enabled:
RD/WT
key is used to read out the data in Pr.00 (minimum value is Pr.16)
▲
key is used to increase the set frequency or the data read from Pr.00.
▼
key is used to decrease the set frequency or the data read from Pr.00.
STOP
key is used for cursor shift
Procedure:
a.
Under normal CTL mode, push RD/WT will enter
Set Frequency mode
, the display will show the value stored in
Pr.00 and blinking the data.
b.
Push
▲
or
▼
, the display starts to show the cursor position.
c.
Push
▲
or
▼
, in order to modify the Panel set frequency.
d.
Push CTL/MON key will go back to normal CTL mode.
Note: If Pr.40=8, the newly modified Set Frequency will write into Pr.00 automatically.
3.2 MON mode
Push the "CTL/MON" key, will change the keypad operation between "CTL" and "MON" Mode.
Under "MON" Mode, user can control the inverter running in either direction and may monitor any two internal status
easily. (Refer to Sec.13)
If "HZ" Led is on, it is under "MON" Mode and 7-segment shows the "HZ" data.
(Or the desired parameter assigned
by Pr.99)
If "I" Led is on, it is under "MON" Mode and 7-segment shows the "I" data.
(Or the desired parameter assigned by
Pr.98)
FWD
key is used for running the inverter in forward direction.
REV
key is used for running the inverter in reverse direction.
STOP
key is used to STOP the inverter.
▲
key is used to select "HZ" or "I" data shown on the 7-segment display.
▼
key is used to select "HZ" or "I" data shown on the 7-segment display.
3.3 PAR mode
Push the "PAR/ALM" key, will change the keypad operation between "PAR" or "ALM" mode.
If push PAR/ALM key, 7-segment shows "Pr.xx", it is under "PAR" Mode.
If push PAR/ALM key, 7-segment shows "0.-xx", it is under "ALM" Mode.
For PDA/E series, under PAR mode, the HZ and I lamps all ON.
Under "PAR" Mode, user can modify or monitor all the internal PARAMETERS.
To modify a parameter, follow the steps described below:
STEP 1: push "PAR/ALM" key, the 7-segment will show "Pr.nn". (nn is parameter number)
STEP 2: push
▲
or
▼
key to select desired parameter number,
and "STOP" key used as cursor shift
.
STEP 3: push "RD/WT" key to READ the content of the specified parameter.
The 7-segment now shows the value of this parameter.
STEP 4: push
▲
or
▼
key to modify the displayed value,
and "STOP" key used as cursor shift
.
STEP 5: push "RD/WT" key to WRITE the new value into parameter memory.
STEP 6: push "PAR/ALM" repeat STEP 1 to modify next parameter.
3.4 ALM mode
Push the "PAR/ALM" key, will change the keypad operation between "PAR" or "ALM" mode.
If push PAR/ALM key, 7-segment shows "0.-xx", it is under "ALM" Mode.
Under "ALM" Mode, the user can execute RESET function or monitor ALARM STATUS.
STOP/RESET
key, the inverter will execute RESET function.
▲
and
▼
key are used to check ALARM History.
