Possible Solutions
You entered an incorrect password in
A1-04 [Password]
.
•
Enter the correct password to
A1-04
again.
•
If you forgot the password, set the password again with
A1-04
and
A1-05 [Password Setting]
.
Note:
If you set the password, you cannot change these parameters until the password aligns:
•
A1-01 [Access Level Selection]
•
A1-03 [Initialize Parameters]
•
A1-06 [Application Preset]
•
A2-01 to A2-32 [User Parameter 1 to User Parameter 32]
The drive detected
Uv [Undervoltage]
.
•
View
U1-07 [DC Bus Voltage]
to see the power supply voltage.
•
Examine the main circuit wiring.

The Motor Does Not Rotate After Entering Run Command
Causes
Possible Solutions
The drive is not in Drive Mode.
1.
Make sure that the keypad shows [Rdy].
2.
If the keypad does not show [Rdy], go back to the Home screen.
Auto-Tuning completed.
Go back to the Home screen on the keypad.
Note:
When Auto-Tuning completes, the drive changes to Programming Mode. The drive will not
accept a Run command unless the drive is in Drive Mode.
The drive stopped, you pushed
, and changed the Run command source
to the keypad.
Do one of these two:
•
Push
.
•
Re-energize the drive.
The drive received a fast stop command.
Turn off the fast stop input signal.
The settings for the source that supplies the Run command are incorrect.
Set
b1-02 [Run Command Selection 1]
correctly.
The frequency reference source is set incorrectly.
Set
b1-01 [Frequency Reference Selection 1]
correctly.
There is defective wiring in the control circuit terminals.
•
Correctly wire the drive control circuit terminals.
•
View
U1-10 [Input Terminal Status]
for input terminal status.
The settings for voltage input and current input of the master frequency
reference are incorrect.
Examine these analog input terminal signal level settings:
•
Terminal A1: Jumper switch S1 and
H3-01 [Terminal A1 Signal Level Select]
•
Terminal A2: Jumper switch S1 and
H3-09 [Terminal A2 Signal Level Select]
The selection for the sinking/sourcing mode and the internal/external power
supply is incorrect.
•
For sinking mode, close the circuit between terminals SC-SP with a wire jumper.
•
For sourcing mode, close the circuit between terminals SC-SN with a wire jumper.
•
For external power supply, remove the wire jumper.
The frequency reference is too low.
•
View
U1-01 [Freq Reference]
.
•
Increase the frequency reference to a value higher than
E1-09 [Minimum Output Frequency]
.
The MFAI setting is incorrect.
•
Make sure that the functions set to the MFAI are correct. The frequency reference is 0 when
H3-
02, H3-10 = 1 [MFAI Function Select = Frequency Gain]
and voltage (current) is not input.
•
View
U1-13 and U1-14 [Terminal A1, A2 Input Voltage]
to see if the analog input values set to
terminals A1 and A2 are applicable.
was pushed.
Turn the Run command OFF then ON from an external input.
Note:
When you push
during operation, the drive will coast to stop. Set
o2-02 = 0 [STOP Key
Function Selection = Disabled]
to disable the
function.
The 2-wire sequence and 3-wire sequence are set incorrectly.
•
Set one of the parameters
H1-03 to H1-07 [Terminals S3 to S7 Function Select]
to
0 [3-Wire
Sequence]
to enable the 3-wire sequence.
•
If a 2-wire sequence is necessary, make sure that
H1-03 to H1-07 ≠ 0
