Motor Does Not Rotate Properly after Pressing RUN Button or after Entering External
Run Command
n Motor Does Not Rotate
Cause
The drive is not in the Drive Mode.
The LO/RE key was pushed.
Auto-Tuning has just completed.
A Fast Stop was executed and has not yet been reset. Reset the Fast Stop command.
Settings are incorrect for the source that provides the
Run command.
There is faulty wiring in the control circuit terminals.
The drive has been set to accept the frequency
reference from the incorrect source.
The terminal set to accept the main speed reference is
set to the incorrect voltage and/or current.
Selection for the sink/source mode and the internal/
external power supply is incorrect.
Frequency reference is too low.
Multi-function analog input is set up to accept gain for
the frequency reference, but no voltage (current) has
been provided.
The STOP key was pressed when the drive was started
from a REMOTE source.

• If the password entered to A1-04 does not match the password saved to A1-05, then drive
settings cannot be changed.
• Reset the password.
If you cannot remember the password:
•
STOP
Scroll to A1-04. Press
• Set a new password to parameter A1-05.
• Check the drive input power voltage by looking at the DC bus voltage (U1-07).
• Check all main circuit wiring.
• Check if the DRV light on the digital operator is lit.
• Enter the Drive Mode to begin operating the motor.
Clock Adjustment Modes on page
Stop the drive and check if the correct frequency reference source is selected. If the operator keypad
shall be the source, the LO/RE key LED must be illuminated. If the source is REMOTE, it must
be off.
Take the following steps to solve the problem:
• Push the LO/RE key.
• If o2-01 is set to 0, then the LO/RE key will be disabled.
• When Auto-Tuning completes, the drive is switched back to the Programming Mode. The Run
command will not be accepted unless the drive is in the Drive Mode.
• Use the digital operator to enter the Drive Mode.
Adjustment Modes on page
Check parameter b1-02 (Run Command Selection).
Set b1-02 so that it corresponds with the correct Run command source.
0: Digital operator
1: Control circuit terminal (default setting)
2: MEMOBUS/Modbus communications
3: Option card
• Check the wiring for the control terminal.
• Correct wiring mistakes.
• Check the input terminal status monitor (U1-10).
Check parameter b1-01 (Frequency Reference Selection 1).
Set b1-01 to the correct source of the frequency reference.
0: Digital operator
1: Control circuit terminal (default setting)
2: MEMOBUS/Modbus communications
3: Option card
4: Pulse train input (RP)
Refer to Terminals A1, A2, and A3 Input Signal Selection on page
Check jumper S3. Refer to Sinking/Sourcing Mode for Digital Inputs on page
• Check the frequency reference monitor (U1-01).
• Increase the frequency by changing the maximum output frequency (E1-09).
• Check the multi-function analog input settings.
• Check if analog input A1, A2, or A3 is set for frequency reference gain (H3-02, H3-10, H3-06
= 1). If so, check if the correct signal is applied to the terminal. The gain and the frequency
reference will be 0 if no signal is applied to the gain input.
• Check if H3-02, H3-10, and H3-06 have been set to the proper values.
• Check if the analog input value has been set properly. (U1-13 to U1-15)
• Pressing the STOP key will decelerate the drive to stop.
• Switch off the Run command and then re-enter a new Run command.
• Set o2-02 to 0 to disable the STOP key.
