Fault Message/Warning Cause
n170 Customer profile table is not initial-
ized.
Appears with n160, when you try to trigger a motion task
that uses a customer profile table for generating the veloc-
ity profile and when the selected profile table is empty
(see MT.CNTL and MT.TNUM.
F201 Internal RAM failed. Hardware failure detected.
F202 External RAM failed. Hardware failure detected.
F203 Code integrity failed. Software failure detected. FPGA register access failure
occurred.
F204 to F232 EEPROM failure detected EEPROM failure detected
F234 to F237
n234 to n237
Temperature sensor high. High temperature limit reached.
F240 to F243
n240 to n243
Temperature sensor low. Low temperature limit reached.
F245 External fault. This fault is user generated and is caused by user set-
tings.
F247 Bus voltage exceed allowed thresh-
olds.
Hardware problem in bus measurement.
F248 Option board EEPROM corrupted. EEPROM failure detected.
F249 Option board downstream checksum. Communications with the I/O on the option board failed.
F250 Option board upstream checksum. Communications with the I/O on the option board failed.
F251 Option board watchdog. Communications with the I/O on the option board failed.
F252 Firmware and option board FPGA
types are not compatible.
The option board FPGA is not compatible with this hard-
ware.
F253 Firmware and option board FPGA ver-
sions are not compatible.
The version of the option board FPGA is not compatible
with this firmware.
F301
n301
Motor overheated. Motor overheated.
F302 Over speed. Motor exceeded VL.THRESH value.
F303 Runaway. Motor did not follow command values.
F304
n304
Motor foldback. Maximum motor power has been exceeded; the power
has been limited to protect the motor
F305 Brake open circuit. Motor brake open circuit. Fault threshold is 200 mA.

t load. Motor I2t load (IL.MI2T) has exceeded the warning thresh-
old IL.MI2TWTHRESH.Can only be generated if
IL.MIMODEhas been set to 1.
F312 Brake released when it should be
applied.
