254 ACE-tronics G9 ASD Installation and Operation Manual
Trips/Faults
A Trip is an ASD response to a Fault (though Fault and Trip are sometimes used interchangeably). A
Trip is a safety feature that disables the ASD system in the event that a subsystem of the ASD is
malfunctioning or a parameter setting has been exceeded.
Listed in Table 15 are the Faults that may result in a Trip and the possible causes. When a Trip is
incurred the LCD screen shows the Fault screen and the LED screen displays the active Fault code.
Table 15. ACE-tronics G9 ASD Fault Listing.
LCD Screen LED Screen Possible Causes
Analog Input Loss E-18 • V/I signal loss.
• ACE G9-120V-PCB failure.
• P24 over-current condition.
• F633 setting is too high.
Analog Input
Over-Voltage
E-10 • Over-voltage at the V/I, RX, or RR input(s).
ASD Overload OL1 • Acceleration time is too short.
• DC Injection current is too high.
• Improper V/f setting.
• Motor running during restart.
• ASD or the motor is improperly matched to the application.
Autotune Error ETN • Autotune readings that are significantly inconsistent with the
configuration information.
• A non-3-phase motor is being used.
• Incorrect settings at F400 or F413.
• Using a motor that has a significantly smaller rating than the ASD.
• ASD output cabling is too small, too long, or is being housed in a cable
tray with other cables that are producing an interfering EMF.
• Motor is running during the Autotune function.
ETN1 • F402 adjustment required (Motor temperature is too high).
• F410 adjustment required (Motor Constant 1 improperly set).
ETN2 • F412 adjustment required (Motor Constant 3 improperly set).
ETN3 • Autotune setting F400 is set to Auto Calculation and there is a
problem with the Motor Constant readings; F405, F406, and F407.
Brake Sequence
Response Error
E-11 • F630 is set to a non-zero value.
• Braking sequence discrete input and output terminals are not setup
properly.
Communication
Error
ERR5 • Communication time out error.
• Communication malfunction.
• Improper or loose connection.
• Improper system settings.
