Table 6.3 Error Displays, Causes, and Possible Solutions 
Parameter Range 
Setting Error 
Parameters are set outside of 
the possible setting range 
1.  Set the parameters to the 
proper values 
2.  Reset the drive   
Multi-Function 
Input Selection 
Error 
1. Either of Up command and 
Down command is not set 
(E1-□□= 10 or 11 )   
2. Either of Up command 2 
and Down command 2 is not 
set (E1-□□=12 or 13)   
Properly assign both of the UP and 
Down commands to the multi-
function input terminal. 
3-Wire  Sequence 
Control  Setting 
Error 
Multi-Function input 
terminals S1 and S2 are 
assigned to E1-□□= 2 (3-Wire 
Sequence) 
Do not assign multi-function input 
terminals S1 and S2 to E1-□□= 2 (3  –
Wire Sequence) 
PID Control 
Selection Fault 
(When b5-00 (PID 
Control Setting)= 1 
to 4) 
1.  Contradictory settings 
·  b5-14 (PID Sleep Start 
Level) is not set to 0.0 
·  b1-02 (Stopping Method 
Selection) is set to 2 (DC 
Braking to Stop) or 3 (Coast 
to Stop with Timer) 
2. L2-01 (Frequency 
Command Lower Limit)≠0 
when b5-00 = 1 or 2 (PID 
Control Enabled) 
3. b5-10 (PID Output Reverse 
Selection) = 1 (Reverse 
Enabled)    when b5-00 = 1 or 
2 
4. L2-01  ≠  0 when b5-00 = 3 
or 4 
1. Correct the parameter setting. 
2. Correct the parameter setting. 
3. Correct the parameter setting. 
4. Correct the parameter setting. 
V/F parameters setting 
incorrect   
Correct the setting in d1-02, d1-04, 
d1-06, d1-08 and d1-09.
