Device added
(same type)
Option board added.
Subcodes:
S1 = Control board
S4 = Control unit
S5 = Adapter board and slot
Reset. Device is ready for
use.
Old board settings will be
used.
39 Device removed Option board removed.
Reset. Device no longer
available.
40
Device unknown
Unknown option
board or drive.
Subcode in T.14:
S1 = Unknown device
S2 = Power1 not same type as Power2
S3 = NXS or NXP1 and star coupler
S4 = Software and ctrl unit incompatible
S5 = Old control board version
Contact your local distribu-
tor.
41 IGBT temperature
IGBT Inverter Bridge overtemperature
protection has detected too high a short
term overload current
Check loading.
Check motor size.
42
Brake resistor
overtemperature
Subcodes:
S1 = Internal brake chopper overtemp.
S2 = Brake resistance too high (BCU)
S3 = Brake resistance too low (BCU)
S4 = Brake resistance not detected (BCU)
S5 = Brake resistance leakage (earth
fault) (BCU)
Reset unit.
Set the deceleration time
longer and restart.
Dimensioning of the brake
chopper is not correct.
Use external brake resistor.
43 Encoder fault
Problem detected in encoder signals.
Sub code in T.14:
S1 = Encoder 1 channel A is missing
S2 = Encoder 1 channel B is missing
S3 = Both enc. 1 channels are missing
S4 = Encoder reversed
S5 = Encoder board missing
S6 = Serial communication fault
S7 = Channel A/Channel B mismatch
S8 = Resolver/Motor pole pair mismatch
S9 = Missed start angle
Check encoder channel
connections.
Check the encoder board.
44
Device changed
(different type)
Option board or power unit changed.
New device of different type or different
rating than the previous one.
Subcodes:
S1 = Control board
S2 = Control unit
S3 = Power board
S4 = Power unit
S5 = Adapter board and slot
Reset
Set the option board
parameters again if option
bard changed. Set AC drive
parameters again if power
unit changed.
