Chapter 7 Troubleshooting
General Troubleshooting These conditions do not always result in a fault code, but can require
troubleshooting to improve performance.
Link A Status Indicator (Ethernet Port 1)
Condition Status
Off Drive is not connected to the network.
Steady Green Drive is connected to the network but not transmitting data.
Flashing Green Drive is connected to the network and transmitting data.
Link A Status Indicator (Ethernet Port 2)
Condition Status
Off Drive is not connected to the network.
Steady Green Drive is connected to the network but not transmitting data.
Flashing Green Drive is connected to the network and transmitting data.
General Troubleshooting
Condition Potential Cause Possible Resolution
Axis or system is unstable. The position feedback device is incorrect or open. Check wiring.
Motor tuning limits are set too high. Run Tune in the Logix Designer application.
Position loop gain or position controller accel/decel rate is improperly set. Run Tune in the Logix Designer application.
Improper grounding or shielding techniques are causing noise to be
transmitted into the position feedback or velocity command lines, causing
erratic axis movement. Check wiring and ground.
Motor Data is incorrectly set (induction motor is not matched to axis module). • Check setups.
• Run Motor Test in the Logix Designer application.
Mechanical resonance. Notch filter or output filter can be required (refer to Axis
Properties dialog box, Output tab in the Logix Designer
application).
You cannot obtain the motor
acceleration/deceleration that you
want. Torque Limit limits are set too low. Verify that torque limits are set properly.
Incorrect motor selected in configuration. Select the correct motor and run Tune in the Logix Designer
application again.
The system inertia is excessive. • Check motor size versus application need.
• Review induction system sizing.
The system friction torque is excessive. Check motor size versus application need.
Available current is insufficient to supply the correct accel/decel rate. • Check motor size versus application need.
• Review induction system sizing.
Acceleration limit is incorrect. Verify limit settings and correct them, as necessary.
Velocity Limit limits are incorrect. Verify limit settings and correct them, as necessary.
Motor does not respond to a
command. The motor wiring is open. Check the wiring.
The motor cable shield connection is improper. • Check feedback connections.
• Check cable shield connections.
The motor has malfunctioned. Repair or replace the motor.
The coupling between motor and machine has broken (for example, the
motor moves, but the load/machine does not). Check and correct the mechanics.
Primary operation mode is set incorrectly. Check and properly set the limit.
Velocity or torque limits are set incorrectly. Check and properly set the limits.
Brake connector not wired Check brake wiring
