Corrective Action/Further information
V phase is not connected to the drive, check that output contactors are closing fully, not arcing,
or not opening whilst the drive is running, and see P10-08 (Motor connected check
W phase is not connected to the drive, check that output contactors are closing fully, not
arcing, or not opening whilst the drive is running, and see P10-08 (Motor connected check
Shown when the rotor speed is higher than 150% of maximum speed (P8-01) (immediate trip)
or higher than 125% maximum speed (P8-01) for more than 100ms, whichever happens first
Press STOP key, the drive is now ready to be configured for the required application
Drive intended for use with a 3 phase supply, one input phase has been disconnected or lost.

Sin Cos A B Line Loss
Sin Cos C Line Loss
Sin Cos D Line Loss
A valid Modbus telegram has not been received within the watchdog time limit set in P5-06
Check the network master / PLC is still operating, Check the connection cables.
Increase the value of P2-06 to a suitable level
A valid CAN open telegram has not been received within the watchdog time limit set in P5-06
Check the network master / PLC is still operating, Check the connection cables.
Increase the value of P2-06 to a suitable level
Internal communication to the inserted Communication Option Module has been lost.
Check the module is correctly inserted
Internal communication to the inserted Option Module has been lost.

Check motor thermistor for wiring faults, check thermistor has not failed.
Encoder Speed Error. The % error between the estimated (open loop)/measured encoder
feedback speed and the actual motor speed is greater than the value set in P6-11 for the time
set in P6-12

Check supply to terminals STO1 and STO2 is >18V, otherwise Refer to your Invertek Sales

Quadrature HTL Over-speed
Refer to your Invertek Sales Partner.
The value set in parameter P10-05 (Travel Direction Change Counter limit) has been reached.
User Parameter defaults have been loaded. Press the Stop key.
This occurs routinely when power is switched off.
If it occurs during running, check the incoming supply voltage, and all connections into the
drive, fuses, contactors etc.
If in rescue mode confirm that the voltage is within the range detailed in section 6.5
If in rescue mode try decreasing rescue mode speed (P7-03)
Whilst operating in Rescue mode the output power to the motor exceeded the value of UPS
rating (P7-04) for the time set in parameter (P7-16) UPS Overload Time Limit, Reduce Rescue
Mode Speed/Motor Load.
Trip occurs when ambient temperature is less than -20°C. The temperature must be raised
Under temperature
over -20°C in order to start the drive.

Confirm that the speed loop gains have been optimised.
In Gearless applications can be caused by excess rollback, see section 14 Comfort
Optimisation
If operating a Gearless motor check the encoder offset is correct and try repeating the
measurement to confirm consistent values are being measured (P4-08 to 3)
In Geared Open loop applications this can be caused by the motor stalling, check :
o
Motor data is correct, and an auto-tune has been performed.
o
Motor rated current is set correctly.
o
Magnetising current in P4-28 is not too high.
o
Brake is releasing.
