Kinetix 5700 Capacitor Module Status Indicators
The 2198-CAPMOD-2240 capacitor module status indicators and module
status (MS) connector are on the front of the module. The module status
connector is a relay output suitable for wiring to a DC-bus power supply digital
input, assigned as Bus Capacitor OK, or the Logix5000 controller.

General Troubleshooting
These conditions do not always result in a fault code, but can require
troubleshooting to improve servo drive performance. See the iTRAK System
User Manual, publication
for general iTRAK troubleshooting.

Condition
Potential Cause
Possible Resolution
Axis or system is unstable.
The position feedback device is incorrect or open.
Check wiring.
Unintentionally in Torque mode.
Check to see what primary operation mode was programmed.
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 Select limit is incorrectly set (servo motor is not matched to axis
module).
• Check setups.
• Run Tune 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).
• Enable adaptive tuning. See
for more notch
filter information.
