CG Drive Trip Errors, Causes and Remedies

Sr. No.	Error	Means	Causes
1	UV	DC bus under voltage	Low AC supply voltage Low DC bus voltage when supplied by an external DC power supply
2	OV	DC bus over voltage	Deceleration rate set too fast for the inertia of the machine Mechanical load driving the motor
3	OI.AC**	Drive output instantaneous over current	Insufficient ramp times Phase to phase or phase to ground short circuit on the drives output Drive requires autotuning to the motor Motor or motor connections changed, re-autotune drive to motor
4	OI.br**	Braking resistor instantaneous over current	Excessive braking current in braking resistor Braking resistor value too small
5	O.SPd	Over speed	Excessive motor speed (typically caused by mechanical load driving the motor)
6	tunE	Auto tune stopped before completion	Run command removed before autotune complete
7	It.br	I2t on braking resistor	Excessive braking resistor energy
8	It.AC	I2t on drive output current	Excessive mechanical load High impedance phase to phase or phase to ground short  circuit at drive output Drive requires re-autotuning to motor
9	O.ht1	IGBT over heat based on drives  thermal model	Overheat software thermal model
10	O.ht2	Over heat based on drives heatsink	Heatsink temperature exceeds allowable maximum
11	th	Motor thermistor trip	Excessive motor temperature
12	O.Ld1*	User +24V or digital output overload	Excessive load or short circuit on +24V output
13	O.ht3	Drive over-heat based on thermal model	Overheat software thermal model
14	O.ht4	Power module rectifier over  temperature	Power module rectifier temperature exceeds allowable maximum
15	cL1	Analog input 1 current mode, current loss	Input current less than 3mA when 4-20 or 20-4mA modes selected
16	SCL	Serial communications loss time-out	Loss of communication when drive is under remote control
17	EEF	Internal drive EEPROM trip	Possible loss of parameter values
18	PH	Input phase imbalance or input phase loss	One of the input phases has become disconnected from the drive (applies to 200/400V three phase drives only, not dual rated drives)
19	rS	Failure to measure motors stator resistance	Motor too small for drive Motor cable disconnected during measurement
20	CL.bt	Trip initiated from the control word	Control word has initiated a trip
21	C.Err	SmartStick data error	Bad connection or memory corrupt within SmartStick
22	C.dAt	SmartStick data does not exist	New/empty SmartStick being read
23	C.Acc	SmartStick read/write fail	Bad connection or faulty SmartStick
24	C.rtg	SmartStick/drive rating change	Already programmed SmartStick read by a drive of a different rating
25	O.cL	Overload on current loop input	Input current exceeds 25mA
26	HFxx trip	Hardware faults	Internal drive hardware fault (see the Advanced User Guide)
Sr. No.	Error	Means	Remedy
27	OVL.d	I x t overload (I = current, t = time)	Reduce motor current (Load)
28	hot	Heatsink/IGBT temperature high	Reduce ambient temperature or reduce motor current
29	br.rS	Braking resistor overload	See Menu 10 in the Advanced User Guide
30	AC.Lt	Drive is in current limit	See Menu 10 in the Advanced User Guide
31	FAIL	Failed attempt to read stick	An attempt has been made to read the stick when the drive was not disabled or tripped, or the stick is read-only

Baumuller Error No. 570

Power section auxiliary voltage supply . + safety relay

The error is triggered if both the auxiliary voltage supply (Error 566) or the power section (internal or external) and the safety relay (error 568) is not switched on. The voltage supply to the transistor triggering is released in the power section via the safety relay. The switching on sequence specified in the documentation must be complied with to avoid error messages when switching in a drive.
The error is fatal and leads to immediate shutoff of the drive controller. In this case the drive coasts to a standstill. Renewed release of the drive by the controller is prevented until the cause of the error has been corrected and the error has been acknowledged.

Source and Remedy 
Check the voltage supply of the auxiliary voltage, Safety relay is switched off
Incorrect activation of the safety relay Examine the activation of the safety relay. 

How to Make Programming of Lenze Drive 9300 Series

By Key Pad

1. Press Program key
2. Press Left Arrow(user mode) key
3. Press Up Arrow (code list) key
4. Press Right Arrow(enter) key
5. Use Up and Down Arrow keys to see different parameters
6. To change parameters first go to parameter no. C002
7. Initially the C002 parameter is always 1. if we want to change the parameters, then first we have to make C002 as 0 otherwise it does not allow to change parameters.
8. But be careful because once we make C002 as 0, all the parameters in the drive goes to factory set values. i.e. default values
9. Then go to the parameters we want to change as per our requirement (press “Shift + Program” key for fast switching between parameters)
10. Press Program key to set new value( set new values using Up and Down Arrow keys)
11. To save the new value press “Shift + Program” key, then OK message appears on the display.
12. Again press program key to return to last menu
13. After changing all  parameters, go to C003 parameter
14. Make C003 parameter as 1 to save and load all changes we made.
