Information Information Installation
Trip
The position feedback did not change or required speed could not be reached during the
tunE1*
inertia test (see Pr 5.12)
Ensure the motor is free to turn i.e. brake was released
Check feedback device wiring is correct
11 Ensure that Pr 3.26 is set correctly
Check feedback parameters are set correctly
Check encoder coupling to motor
Position feedback direction incorrect or motor could not be stopped during the inertia test
tunE2*
(see Pr 5.12)
Check motor cable wiring is correct
12 Check feedback device wiring is correct
Swap any two motor phases (closed loop vector only)
Drive encoder commutation signals connected incorrectly or measured inertia out of
tunE3*
range (see Pr 5.12)
Check motor cable wiring is correct
13
Check feedback device U,V and W commutation signal wiring is correct
tunE4* Drive encoder U commutation signal fail during an autotune
Check feedback device U phase commutation wires continuity
14
Replace encoder
tunE5* Drive encoder V commutation signal fail during an autotune
Check feedback device V phase commutation wires continuity
15
Replace encoder
tunE6* Drive encoder W commutation signal fail during an autotune
Check feedback device W phase commutation wires continuity
16
Replace encoder
tunE7* Motor number of poles set incorrectly
Check lines per revolution for feedback device
17
Check the number of poles in Pr 5.11 is set correctly
Unid.P Power module unidentified trip
Check all interconnecting cables between power modules
110
Ensure cables are routed away from electrical noise sources
UP ACC Onboard PLC program: cannot access Onboard PLC program file on drive
Disable drive - write access is not allowed when the drive is enabled
98
Another source is already accessing Onboard PLC program - retry once other action is complete
UP div0 Onboard PLC program attempted divide by zero
90 Check program
Onboard PLC program variables and function block calls using more than the allowed
UP OFL
RAM space (stack overflow)
95 Check program
UP ovr Onboard PLC program attempted out of range parameter write
94 Check program
UP PAr Onboard PLC program attempted access to a non-existent parameter
91 Check program
UP ro Onboard PLC program attempted write to a read-only parameter
92 Check program
UP So Onboard PLC program attempted read of a write-only parameter
93 Check program
UP udF Onboard PLC program un-defined trip
97 Check program
UP uSEr Onboard PLC program requested a trip
96 Check program
