The Motor Does Not Rotate After Entering Run Command

Causes
The drive is not in Drive Mode.
The drive stopped, was pushed, and changed the Run command source
to the keypad.
Auto-Tuning completed.
The drive received a fast stop command.
The settings for the source that supplies the Run command are incorrect.
The frequency reference source is set incorrectly.
There is defective wiring in the control circuit terminals.
The settings for voltage input and current input of the master frequency
reference are incorrect.
The selection for the sinking/sourcing mode and the internal/external power
supply is incorrect.
The frequency reference is too low.
The MFAI setting is incorrect.
was pushed.
The 2-wire sequence and 3-wire sequence are set incorrectly.

• 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]
• A1-02 [Control Method Selection]
• A1-03 [Initialize Parameters]
• A1-06 [Application Preset]
• A1-07 [DriveWorksEZ Function Selection]
• A2-01 to A2-32 [User Parameter 1 to User Parameter 32]
• View U1-07 [DC Bus Voltage] to see the power supply voltage.
• Examine the main circuit wiring.
1. Make sure that the keypad shows [Rdy].
2. If the keypad does not show [Rdy], go back to the Home screen.
Do one of these two:
• Push
.
• Re-energize the drive.
Note:
Set o2-01 = 0 [LO/RE Key Function Selection = Disabled] to prevent changing the Run
command source with .
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.
Turn off the fast stop input signal.
Set b1-02 [Run Command Selection 1] correctly.
Set b1-01 [Frequency Reference Selection 1] correctly.
• Correctly wire the drive control circuit terminals.
• View U1-10 [Input Terminal Status] for input terminal status.
Examine these analog input terminal signal level settings:
• Terminal A1: DIP switch S1-1 and H3-01 [Terminal A1 Signal Level Select]
• Terminal A2: DIP switch S1-2 and H3-09 [Terminal A2 Signal Level Select]
• Terminal A3: DIP switch S4, S1-3 and H3-05 [Terminal A3 Signal Level Select]
• 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.
• View U1-01 [Freq Reference].
• Increase the frequency reference to a value higher than E1-09 [Minimum Output Frequency].
• Make sure that the functions set to the MFAI are correct. The frequency reference is 0 when H3-
02, H3-10, H3-06 = 1 [MFAI Function Select = Frequency Gain] and voltage (current) is not
input.
• View U1-13 to U1-15 [Terminal A1, A2, A3 Input Voltage] to see if the analog input values set to
terminals A1, A2, and A3 are applicable.
Turn the Run command OFF then ON from an external input.
Note:
When you push during operation, the drive will ramp to stop. Set o2-02 = 0 [STOP Key
Function Selection = Disabled] to disable the
• Set one of the parameters H1-03 to H1-08 [Terminals S3 to S8 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 H1-08 ≠ 0.
