All other errors
Cause:

Internal supply error, encoder supply error, parameter restore failure, or power base not recognized.


Remedy:


  • Check power supplies and encoder wiring.

  • Refer to Mint WorkBench “Error Handling” book.
Status LED: Alt. Red/Green

Undervoltage warning
Cause:

DC-bus voltage dropped below powerbase undervoltage level (no AC power).


Remedy:


  • Check that AC power is connected.
Communication Fault

Status LED is off
Cause:

Control circuit power is missing or disconnected.


Remedy:


  • Check that the 24 V DC control circuit supply is connected correctly to connector X2.

  • Ensure 24 V DC supply is switched on.
Firmware Fault

ETHERNET LEDs blinking green and red simultaneously
Cause:

Firmware download failed or no firmware present.


Remedy:


  • Download new firmware to the MicroFlex e100.
Connection Fault

Mint WorkBench fails to detect the MicroFlex e100
Cause:

Cabling issues, driver issues, or incorrect configuration.


Remedy:


  • Ensure the drive is powered and Status LED is illuminated.

  • Check Ethernet or USB cable connections.

  • Try an alternative cable or different PC port.

  • In Mint WorkBench “Select Controller” dialog, increase “Search up to Nodexx” value.

  • For USB: Check device is listed in Windows Device Manager as ‘USB Motion Controller’.

  • For Ethernet: Check PC Ethernet port is configured for TCP/IP operation.
Power On Fault

Drive does not start when applying AC power
Cause:

Motor output phases might be short-circuited.


Remedy:


  • Check that motor output phases are not short circuited.

  • Remove all power, correct the short circuit, and restart the drive.
Mint WorkBench Fault

The Spy window does not update
Cause:

System refresh has been disabled.


Remedy:


  • Go to Tools > Options > System tab.

  • Choose a System Refresh Rate (500 ms recommended).
USB Communication Fault

Mint WorkBench loses contact while using USB
Cause:

Power loss or PC USB interface issue.


Remedy:


  • Check that the MicroFlex e100 is powered.

  • Check that ‘USB Motion Controller’ is listed in Windows Device Manager.
Error 10010

Cannot enable the MicroFlex e100
Cause:

Drive enable input issue.


Remedy:


  • Check the drive enable input on connector X3 pins 9 and 19 is connected and powered correctly.
Tuning Issue

Motor is unstable when enabled
Cause:

Load coupling or tuning parameters.


Remedy:


  • Check that the load is firmly coupled to the motor.

  • Use Mint WorkBench Drive Setup Wizard to confirm motor data.

  • Use Mint WorkBench Autotune Wizard to retune the motor.

  • If still unstable, lower bandwidth in Autotune Options (Current/Position/Speed sliders).
Ethernet Fault

Slow response when issuing command from host
Cause:

TCP/IP socket closed due to inactivity (30 seconds).


Remedy:


  • Include a timed procedure in your application (period < 30s) that issues a command (e.g., reading AAABuild) to keep the socket open.
CANopen Fault

CANopen bus is ‘passive’
Cause:

Tx/Rx errors > 127 (Passive Threshold).


Remedy:


  • Check 12-24 V is applied to OPT 1 connector (pins 9 and 6/3).

  • Ensure at least one other node is on the network.

  • Check termination is only at ends.

  • Check baud rate and unique node IDs.

  • Check integrity of CAN cables.
CANopen Fault

CANopen bus is ‘off’
Cause:

Tx/Rx errors > 255 (Fatal Threshold).


Remedy:


  • Remove source of errors (check cabling, termination, power).

  • Reset bus using Mint BUSRESET keyword or reset the drive.
CANopen Fault

Manager node cannot scan/recognize a node
Cause:

Node configuration or compatibility issue.


Remedy:


  • Check node has a unique ID.

  • Ensure node supports node guarding (MicroFlex e100 does not support Heartbeat).

  • Power-cycle the node in question.

  • Note: Only DS401/DS403/ABB nodes are recognized by NODESCAN.
