Error Code #
Indication
Type
331 Instantaneous Input Current Limit
Instantaneous input current limit has been exceeded. Typically indicates short
term power overload. If problem persists contact Service Department.
Persistent
334 Startup Current Check Failure
Input current limit was exceeded during machine power-up. If problem per-
sists contact Service Department.
Persistent
335 Startup Voltage Check Failure
Input voltage was too high or too low during machine power-up. Verify that
the input voltage is between 200V and 650V.
Temporary
336 Thermal Fault
Thermostat on primary module tripped. Typically caused by a fan malfunction
or blocked air vent.
Temporary
337 Precharge Timeout
The DC bus voltage was not charged to a certain level at end of precharge. If
problem persists contact Service Department.
Persistent
338 Input Power Limit
The input power drawn by the machine exceeded a safe level. If problem per-
sists, contact the Service Department.
Persistent
341 Input Voltage Dropout
The input voltage momentarily dropped out. Check connections and verify
quality of input power.
Temporary
346 Transformer Primary Overcurrent
Transformer current too high. Typically indicates short-term power overload. If
problem persists, contact the Serivce Department.
Persistent
347 Average Input Current Limit
Average input current limit has been exceeded. Typically indicates short term
power overload. If problem persists contact Service Department.
Persistent
349 Bus Undervoltage
The DC bus voltage dropped below the allowable limit. If problem persists,
contact the Service Department.
Temporary
Persistent errors require power to be cycled for the error to clear.
Temporary faults will go away on their own if the error condition is removed.
WIRE DRIVE MODULE
Error Code #
81 Motor Overload
82 Motor Overcurrent
83 Shutdown #1 Is Open
84 Shutdown #2 Is Open
Indication
Long term average motor current limit has been exceeded. Typically indicates
mechanical overload of system. If problem continues consider higher torque gear
ratio (lower speed range).
Absolute maximum motor current level has been exceeded. This is a short term
average to protect drive circuitry.
1.This refers to the ‘green’ I/O connector on the bottom of the controller.
If not being externally accessed, verify the integrity of the connector and jumper.
If accessed through a remote circuit, verify the integrity of that circuit.
