11201

--

----

 

 

Gives feedback status information when the

 

 

 

 

 

 

 

 

 

 

 

 

 

DRIVEMODE parameter (1201) was used to start the

 

 

 

 

 

 

 

 

 

 

 

 

 

drive function 3, 5 or 6 (autotuning).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

50

OHMIC LOAD ?

 

Ohmic load not determined

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

51

IACT FEEDBACK ?

 

Current feedback is less than current reference dur-

 

 

 

 

 

 

 

 

 

 

 

 

 

ing measurement of armature resistance. Current

 

 

 

 

 

 

 

 

 

 

 

 

 

limits are lower than the limit for continous current

 

 

 

 

 

 

 

 

 

 

 

 

 

flow or lower than 20%.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

52

CURRENT CURVE ?

 

Bad current curve. Fuse blown,thyristor not firing or

 

 

 

 

 

 

 

 

 

 

 

 

 

no motor load

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

53

RUN COMMAND ?

 

Wrong starting conditions. The drive is running when

 

 

 

 

 

 

 

 

 

 

 

 

 

the autotuning is started or run command is not given

 

 

 

 

 

 

 

 

 

 

 

 

 

within 20 s after start of autotuning

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

54

TOO HIGH SPEED ?

 

Too high speed during autotuning .Speed greater

 

 

 

 

 

 

 

 

 

 

 

 

 

than 1% or EMF greater than 15%.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

55

INDUCTANCE ?

 

Inductance cannot be determined. Fuse blown, thy-

 

 

 

 

 

 

 

 

 

 

 

 

 

ristor not firing or no motor load

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

56

CONT CURR LIM ?

 

Limit for continous current flow cannot be determined

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

57

FIELD REMOVAL ?

 

The field removal takes longer time than 10 s

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

58

STOP COMMAND ?

 

Current regulator blocking or stop command appears

 

 

 

 

 

 

 

 

 

 

 

 

 

during autotuning

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

59

MUST BE LOCAL

 

Drive is not in local mode

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

60

CANNOT AUTOTUNE

 

cannot autotune the field current controller

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

61

ILL START COND.

 

illegal start condition for field autotuning
