t168 to t171
User trip defined in 2
nd
processor Solutions Module code
168 to 171 SM-Applications program must be interrogated to find the cause of this trip

216 SM-Applications program must be interrogated to find the cause of this trip
th Motor thermistor trip
24
Check motor temperature
Check thermistor continuity
Set Pr 7.15 = VOLt and reset the drive to disable this function
thS Motor thermistor short circuit
25
Check motor thermistor wiring
Replace motor / motor thermistor
Set Pr 7.15 = VOLt and reset the drive to disable this function
tunE* Autotune stopped before completion
18
The drive has tripped out during the autotune
The red stop key has been pressed during the autotune
The Safe Torque Off signal (terminal 31) was active during the autotune procedure
tunE1* The position feedback did not change or required speed could not be reached during the inertia test (see Pr 5.12)
11
Ensure the motor is free to turn i.e. brake was released. Check feedback device wiring is correct
Check feedback parameters are set correctly
Check encoder coupling to motor
tunE2* Position feedback direction incorrect or motor could not be stopped during the inertia test (see Pr 5.12)
12
Check motor cable wiring is correct. Check feedback device wiring is correct
Swap any two motor phases
tunE3* Drive encoder commutation signals connected incorrectly or measured inertia out of range (see Pr 5.12)
13 Check motor cable wiring is correct. Check feedback device U,V and W commutation signal wiring is correct
tunE4* Drive encoder U commutation signal fail during an autotune
14
Check feedback device U phase commutation wires continuity
Replace encoder
tunE5* Drive encoder V commutation signal fail during an autotune
15
Check feedback device V phase commutation wires continuity
Replace encoder
tunE6* Drive encoder W commutation signal fail during an autotune
16
Check feedback device W phase commutation wires continuity
Replace encoder
tunE7* Motor number of poles set incorrectly
17
Check lines per revolution for feedback device
Check the number of poles in Pr 5.11 is set correctly
UP ACC Onboard PLC program: cannot access Onboard PLC program file on drive
98
Disable drive - write access is not allowed when the drive is enabled
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
UP OFL Onboard PLC program variables and function block calls using more than the allowed 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
