29 

When the TMS7 enters the trip state the cause of the trip is 
indicated on the LED display panel. 

 

 

0 

Shorted SCR 
The TMS7 has detected a shorted SCR(s). 
1.  Determine the affected phase using the 3 phase 

indicators LEDs located on the left hand side of 
the TMS7 cover. Damaged SCRs are indicated by 

an extinguished phase indicator LED (all phase 
indicator LEDs should be illuminated when input 

voltage is present but the motor is not running). 
SCR damage can be verified using the Power 

Circuit Test described in the Test & Measurement 
chapter of this section. 

2.  Replace the damaged SCR. 

3. 

Reset the trip condition by removing and 

reapplying control voltage to the TMS7. 

2 

Overcurrent trip 
The motor has been overloaded and the motor’s 
thermal limit, as calculated by the TMS7 motor thermal 

model, has been reached. 
1. 

Remove the cause of the overload and let the 

motor cool before restarting. 

3 

Motor thermistor trip 
The motor thermistors have indicated an 

overtemperature situation. 
1.  Identify and correct the cause of the motor 

overheating. 

2.  If no thermistors are connected to the TMS7, 

ensure there is a closed circuit across the motor 
thermistor input (terminals C1 & C2). 

4 

Current imbalance trip 
An imbalance in the phase currents has exceeded the 

limits set in Function 7. Current Imbalance Sensitivity. 
1.  Monitor the supply voltage 
2. 

Check the motor circuit 

5 

Supply frequency trip 
Supply frequency has varied outside the TMS7’s 

specified range. 
1.  Correct the cause of the frequency variations. 
2.  Check the three phase supply to the TMS7. Loss 

of all three phases is seen by the TMS7 as a 0Hz 

situation and may be the cause of a supply 
frequency trip. 

3. 

Check the three phase supply to the TMS7 is 

connected to input terminals L1, L2, L3. Incorrect 
connection of the incoming supply to the output 
terminals T1, T2, T3 means there is no supply 

connected to the TMS7 input. This will be seen as 

connected to the TMS7 input. This will be seen as 
a 0Hz situation and may the cause of a supply 
frequency trip. 

6 

Phase rotation trip 
The TMS7 has detected a phase rotation that has 
been prohibited by the setting made in Function 30. 

Phase Rotation Protection. 
1.  Change the incoming phase rotation. 

7 

Stall trip 
The TMS7 has measured a current equal to the limit 

set in Function 9. Stall Protection. 
1.  Identify and correct the cause of the 

instantaneous overload event. 

8 

Power circuit fault 
The TMS7 has detected a fault in the power circuit. 
1.  Ensure that the motor is correctly connected to 

the TMS7 and verify the circuit. 

2. 

Check that voltage is correctly applied to all three 

TMS7 input terminals (L1, L2 & L3). 

9 

Undercurrent trip 
The TMS7 has measured a run current lower than the 
limit set in Function 8. Undercurrent Protection. 
1.  Identify and correct the cause of the undercurrent 

event. 

F 

Heatsink overtemperature trip 
The TMS7 heatsink temperature sensor has indicated 

and excess heatsink temperature. 
1.  Verify that the TMS7 has sufficient ventilation. 
2.  Verify that cooling air is able to freely circulate 

through the TMS7. 

3. 

Verify that the TMS7 cooling fans (if fitted) are 
working. 

P 

Invalid motor connection 
The TMS7 cannot detect a valid motor circuit. 
1.  Ensure the motor is connected to the TMS7 in a 

valid configuration. Refer to Section 5 Power 
Circuits for further detail. 

C 

RS485 communication fault 
The RS485 link connected to the TMS7 has been 

inactive for a period of time greater than set in 
Function 60. RS485 – Timeout Protection. 
1.  Restore the RS485 link. 

E 

EEPROM read/write failure 
The TMS7 has failed to read or write to the internal 
EEPROM. 
Reset the TMS7. If the problem persists contact your 
supplier. 

 

Out of range FLC 
The TMS7 has detected that the motor is connected in 
the 3 Wire configuration and that Function 1. Motor 

FLC or Function 80 Motor FLC (secondary motor 
settings) has been set in excess of the TMS7’s 
maximum capability  for this connection format. 
1.  Reduce the motor FLC setting and then reset the 

TMS7. Note that the TMS7 cannot be reset until 

the FLC setting has been corrected. 

2. 

Alternatively, remove control voltage from the 

TMS7 and reconnect the motor in 6 Wire.
