Digital Operator Operation Failure Indication
:
Fault Code Content Probable Cause What to do
LOC
Parameter / freq. /
REV direction is
locked
1. Try to change parameter /freq.
when Fn_04 = xxx1 or xx1x
2. Try to run in REV direction
when Fn_03 = x1xx
1. Set Fn_04 = xxx0 or xx0x
2. Set Fn_03 = x0xx
Err1 Operation error
1. Try to change freq. by
pressing
∧
or
∨
when Fn_11 > 0
2. Try to change Fn_124
3. Try to change functions which
cannot be changed during
operation
1. Set Fn_11 = 0
2. Fn_124 (CPU version) cannot be
changed
3. Change those functions in
stop mode
Err2 Setting error
1. Fn_07 is in the range of Fn_65
±
Fn_68, Fn_66
±
Fn_68 or Fn_67
±
Fn_68
2. Fn_06
≤
Fn_07
3. Fn_70
≤
Fn_75
4. Fn_27
≥
Fn_28
1. Adjust Fn_65 - Fn_68 or Fn_07
setting
2. Fn_06 > Fn_07
3. Fn_70 > Fn_75
4. Fn_27 < Fn_28
Err3 Setting error
1. V/F curve is set too steep when
Fn_05= 18
2. Analog freq. signal is set too steep
1. (Fn_38 - Fn_40) / (Fn_37 -
Fn_39)
≤
65, (Fn_40 - Fn_41) /
(Fn_39 - 0.1)
≤
65
Err4 Setting error
1. Incorrect settings of Fn_37 -
Fn_41
1. Fn_37 > Fn_39 > 0.1 Hz
Fn_38
≥
Fn_40
≥
Fn_41
Err5
Parameters setting
error
1. Under disable condition
2. Amend Fn-101 or Fn_102
during communication
1.Set enable before communication
. Fn_101, Fn_102 should be
amended before communication.
Err6
Communication
error
1. Connection error
2. Improper parameters
3. Checksum error
4. Agreement error
1. Investigate connection
2. Check Fn_101, Fn_102
3. Check communication
agreement
4. Check communication
Err7
Parameter setting
error
1. Attempt to change Fn_00 or Fn_96
2. The value in Fn_96 is far from the
value of detected voltage
1. Refer to 2.3 “Changing control
boards”
2. Check PN voltage circuit
