Error Operation Comment
BB off
(instantly after
switching power on )
1) Check encoder and connection 'X3' (if necessary 'XA' / 'XC'),
jumper 'JP3' is not positioned correctly (1Vss or TTL/HTL)
Read the operating
instructions!
2) PTC thermistor plug not connected, one of the phases at
L1...L3 is missing
Series fuses ok?
3) Short-circuit at either 'X1' or the plugs of encoder or interface:
measure pin 20 and 22 at 'X1' against pin 18 (at each case
approx. 15V?), measure pin 3 against pin 4 at 'X3' (5V not there?
-> as a result of short-circuit at 'X3', 'XC' or 'X4' caused the
defect of the internal fuse 2,5A, if you can measure none of the
voltages the power-unit is defect -> send for repair!)
Disconnect all plugs!
4) emergency evacuation activated, but flag 0E62 not set to '0'
'E1'
resp
. '0E62' ok?
BB instantly off
(after ISP and E0)
1) Short-circuit at the motor terminal plate (humidity?), defect
motor supply cable, contactors defect, motor winding defect,
foreign particles
Insulation test?
2) Encoder-cable-screen not or only one-sided contacted to the
housing
Measure against PE
3) Power stage or AddOn of the inverter defect (send for repair)
4) IIdt-timer value (0E5A) is below 250ms (set it to 5000ms)
BB off after a few
seconds
1) IIdt error, because of wrong rotating field allocation or phase-
sequence of the motor, or motor is not connected at all
U1, U2, U3 ->
U, V, W (motor)
2) Motor temperature too high or thermistor is not working
correctly or defect
3) Mechanical stiffness (the brakes unlock not totally)
Motor is rotating
very slow or is
jerking
1) Phase-sequence, phase angle, encoder pulse numbers or
number of motor poles wrong, resp. slow speed instead of high
speed connected (modification – plant with old motor)
Rating plate?
Motor causes heavy
noise ('growling')
1) Amplification values (parameters 'k' and 'f7') adjusted too high,
or possibly encoder-cable-screen is not or only one-sided
contacted to the housing
2) JP3-flag 0E3E is set to '0' although no 1Vss-Encoder is in use
extraneous voltage
24V short-circuited
1) Input/Output at 'X1' or 'X2' short-term over voltage more than
30Vdc (Transildiodes break through -> possibly you have to
remove them)
Avoid suspending
mass as far as
possible
Parameter can not
be modified
1) Data safety switch between 'X3' and 'X4' set to 'R'
(at the top) -> set it to 'RW' (lower position)
2) wrong password or special software inside
After changing data
the drive does not
work
1) Variable/parameter, by mistake, transferred via FU-Control
during the run, modified and stored later
Transfer the
software again from
PC to inverter
After changing the
software the drive
does not work
1) 40-MHz-software transferred into 50-MHz-inverter (or
contrary). Wrong update transferred, chosen option board not
compatible with software (resp. important in regard of 12-bit and
16-bit resolver)
Read the operating
instructions!
Motor is accelerating
very slow
1) Parameter 't' wrong: 'old' silumin motors often have only
double-digit values, new ones always have triple-digit values from
150 to 450 (asynchronous gearless even from 550 to 750)
Read the operating
instructions!
2) Parameter 'f0' wrong: at 10...15A-inverters 'f0'-value can be till
850, for others normally have typical values from 300 to 600
Motor oscillates
during constant
motion
1) I-part 'run' too small: at all 50-MHz-inverters and 40-MHz-
inverters with special software (LIFT7TZ, LAST7TZ) the I-parts
0E1C and 0E1E can be modified separately (set 0E1E to approx.
2...5 times higher than 0E1C)
Read the operating
instructions!
