7.3 Faults
7.3.1 FAULT CODES
Below are fault codes mostly caused by hardware operations. Additional fault codes
are listed in Programmer’s manual.
Fault
Code Fault
Description
F_OU Over voltage
Drive bus voltage reached the maximum level, typically due
to motor regeneration
F_FB Feedback error
Resolver signal lost or at least one motor hall sensor is
inoperable or not connected.
F_OC
Over current
Drive exceeded peak current limit. Software un-capable to
regulate current within 15% for more then 20mS. Usually
results in wrong motor data or poor tuning.
F_Ot Over temperature
Drive heatsink temperature has been reached maximum
rating.
F_EF
External fault input
activated Digital input was programmed as external fault input and has
been activated.
F_OS
Over speed Motor reached velocity above its specified limit
F_PE Excess position error Position error exceeded maximum value.
F_bd
Bad motor data Motor profile data invalid or no motor is selected
F_09
Motor over
temperature Optional motor temperature sensor (PTC) indicates that the
motor windings have reached maximum temperature
F_10
Subprocessor
failure
Error in data exchange between processors. Usually
happens when EMI level is high resulting from poor shielding
and grounding.
F_14
Undervoltage
Happens bus voltage level drops below 50% of nominal bus
voltage while drive is operating. Attempt to enable drive with
low bus voltage also result in this fault.
F_15
Hardware overload
protection Happens if phase current at any time becomes higher than
400% of total drive’s current capability for more then 5uS.
F_33 Negative Limit Switch Negative limit switch is activated
F_34 Positive Limit Switch Positive limit switch is activated
F_36
Drive Disabled by
User at Enable Input
Drive disabled while operating or attempt to enable drive
without deactivating “Inhibit input”. “Inhibit” input has reverse
polarity.
There are additional error codes related to the programming of the 940. Please
reference the programmer’s manual for more information.
7.3.2 Fault Event
When drive encounters any fault, the following events occur:
• Drive is disabled
• Internal status is set to “Fault”
• Fault number is logged in the drive’s internal memory for later interrogation
• Digital output(s), if configured for “Run Time Fault”, are asserted
• Digital output(s), if configured for READY, are de asserted
• If the display is in the default status mode, the LEDs display F_XX where XX is
current fault code.
• “Enable” LED turns OFF
7.3.3 Fault Reset
Fault reset is accomplished by disabling or re-enabling the drive depending on the
setting of the “Reset option” parameter (section 6.3.10).
