3 Startup Procedure and Test Run
Possible Solutions
• Enter the correct password to A1-04 [Password] again.
• If you forgot the password, set the password again with A1-04 and A1-05
[Password Setting].
Note:
If the password is set, these parameters cannot be changed unless the
password matches:
• A1-01 [Access Level Selection]
• A1-02 [Control Method Selection]
• A1-03 [Initialize Parameters]
• A1-06 [Application Preset]
• A2-01 to A2-32 [User Parameter 1 to User Parameter 32]
• Check the power supply voltage with U1-07 [DC Bus Voltage].
• Check the main circuit wiring.
Possible Solutions
Change the motor control method with parameter A1-02 [Control Method
Selection].
Possible Solutions
Give the Run command from the drive control terminals by setting b1-02 =
1 [Digital Input].
Possible Solutions
• Input the signal from the terminal set for the external baseblock signal.
• Avoid using the external baseblock signal.
1. Check whether [Rdy] is displayed on the keypad.
2. If [Rdy] is not displayed, return to the Home screen.
Switch the keypad to the Home screen.
Note:
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.
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.
• Check the input terminal status using U1-10 [Input Terminal Status].
Check the analog input terminal signal level settings.
• Terminal A2: DIP switch S1 and H3-09 [Terminal A2 Signal Level
Select]
• For sinking mode, short circuit terminals SC-SP using a wire jumper.
• For sourcing mode, short circuit terminals SC-SN using a wire jumper.
• In the case of an external power supply, remove the wire jumper.
• Check U1-01 [Frequency Reference].
• Make the frequency reference higher than E1-09 [Minimum Output
Frequency].
