•
1_PWMXX
Note: This code has to convert to decimal.
This code means motor duty (motor speed) at error detection.
If value is more than 128, it means speed-adjusting worked and
(value – 128) is the duty.
•
1__FGXXXX
Left 2numbers : FG counter, place of thousands/hundreds
Right 2numbers : FG counter, place of tens/one
Note:
These 2 code has to convert to binary.
This code means FG counter at error detection.
This has 2meanings as follows:
Bit7 of sensor status FG code means
0 Counter between each sensor
1 Counter every 500 msec
•
1TOUTXX
This code means timer remained.
If value is 0, it means operation-timeout occurred.
If you want to know how many msec remain, (value
×
512) will be
the answer.
Typical Example
•
DROP DW broken
Code Meaning
HIST01 FG counter error
JCPB121 Normally open
SENS9398 Motor driver status 93
→
10010011
Over current permitted
Open direction
Motor Drive
Sensor status 98
→
10011000
FG counter error detected
STOP UP shielded
DROP DW shielded
DROP DW open
PWMBC Duty 188
→
(188 – 128) = 60 % with speed adjust
FG1C58 1C
→
28
58
→
88
means FG was counted 2888 pulse
TOUT13 13
→
19
remains 19
×
512 = 9728 msec remains
FG counter over at open normal operation and DROP DW was
undetected, this code means “DROP DW seems to be broken” or
“Belt was slipped”.
LIFT DEMO MODE
Procedure:
1. Press the
[POWER]
button to turn the power on.
2. Touch and press three buttons of
N x
,
.
