Troubleshooting Chapter 10
➊ See Table 38 for Type description.
F81 Comm Loss 2 RS485 (DSI) port stopped
communicating.
30. Turn off using Parameter 205 (Comm Loss Action).
31. Replace starter module if fault cannot be cleared.
F100 Parameter
Checksum
2 The checksum read from the board does
not match the checksum calculated.
32. Set Parameter 141 (Reset To Defaults) to Option 1 (Reset Defaults).
F122 I/O Board Fail 2 Failure has been detected in the drive
control and I/O section.
33. Cycle power.
34. Replace starter module if fault cannot be cleared.
Table 39 - Bulletin 284E Faults – Parameters 107, 108, and 109 (Fault 1, 2 or 3)
No. Fault
Type
➊ Description Action
Table 40 - Motor Does Not Start
Cause(s) Indication Corrective Action
No output voltage to the motor. None Check the power circuit.
• Check the supply voltage.
• Check all fuses and disconnects
Check the motor.
• Verify that the motor is connected properly.
• Verify that I/O Terminal 01 is active.
• Verify that Parameter 136 (Start Source) matches your configuration.
• Verify that Parameter 195 (Reverse Disable) is not prohibiting movement.
Drive is Faulted Flashing red status light Clear fault.
• Press Stop
• Cycle power
• Set Parameter 200 (Fault Clear) to Option 1 (Clear Faults).
• Cycle digital input is Parameters 151…154 (Digital In x Sel) is set to Option 7, (Clear
Faults).
Table 41 - Drive Does Not Respond to Changes in Speed Command
Cause(s) Indication Corrective Action
No value is coming form the
source of the command.
The drive Run indicator is lit
and output is 0 Hz.
• Check Parameter 112 (Control Source) for correct source.
• If the source is an analog input, check wiring and use a meter to check for presence of
signal.
• Check Parameter 102 (Commanded Freq) to verify correct command.
Incorrect reference source is
being selected via remote device
or digital inputs.
None • Check Parameter 112 (Control Source) for correct source.
• Check Parameter 114 (Dig In Status) to see if inputs are selecting an alternate source. Verify
settings for Parameters 151…154 (Digital In x Sel).
• Check Parameter 138 (Speed Reference) for the source of the speed reference. Reprogram
as necessary.
Table 42 - Motor and/or Drive Will Not Accelerate to Commanded Speed
Cause(s) Indication Corrective Action
Acceleration time is excessive. None Reprogram Parameter 139 (Accel Time 1) or Parameter 167 (Accel Time 2).
Excess load or short acceleration
times force the drive into current
limit, slowing, or stopping
acceleration.
None • Compare Parameter 103 (Output Current) with Parameter 189 (Current Limit1).
• Remove excess load or reprogram Parameter 139 (Accel Time 1) or Parameter 167 (Accel
Time 2).
• Check for improper setting of Parameter 184 (Boost Select).
