Name [ID] Description Def.
External fault
inactive [529]
External fault deactivation: In case of a numeric signal if the signal value is
lower than the defined level.
Look choises of parameter's Binary inputs [184] (page 17)
7.8.2 ENC. FAULTS
Group of parameters number [990]
Setting the fault evaluation of the encoders.
MENU \ SETTINGS \ FAULTS AND WARNINGS \ ENC. FAULTS
Name [ID] Description Def.
Encoder fault
mode [535]
Turning on the testing of motor rotation speed sensor loss and the
configuration of the testing method. Fault evaluation is recommended for
closed loop control with the feedback from the encoder.
Selecting the evaluation method of IRC/ARC encoder fault evaluated by the
extension module and the converter control board.
Wrong
direction
□ ERR output RM -
IRC
Fault " E32-IRC fault (page 33)" is evaluated during missing or incomplete signals A,
AN, B, BN, I, IN.
□ Incorrect
reverses of IRC1
Fault " E32-IRC fault (page 33)" is evaluated during high presence of incorrect IRC1
reverses at high speed.
□ Incorrect
reverses of IRC2
Fault " E32-IRC fault (page 33)" is evaluated during high presence of incorrect IRC2
reverses at high speed.
□ Switch to OPEN
If this option is active, during the IRC for ramp-down the converter generates only
warnings and switches to an open scalar or vector control.
□ Warning onl y
IRC fault maintenance will operate according to previous options, but it will not generate
the fault, only a warning.
□ Disconnected /
broken IRC
Fault " E32-IRC fault (page 33)" is evaluated by saturated torque and current controllers
and a longer zero speed period in vector control.
□ Speed step
change
Fault " E32-IRC fault (page 33)" is generated during high, unlike speed step change.
■ Wrong direction
Warning " W59-Incorrect IRC/ARC direction (page 31)" or fault " E59-Incorrect
IRC/ARC direction (page 34)" are generated when wrong IRC or ARC direction is
detected.
□ High frequency
Fault " E32-IRC fault (page 33)" is evaluated after exceeding the speed set by the
parameter High freq. encoder [1612] (page 109).
Incor. rev. IRC
sensitivity [9]
Setting the sensitivity of "Incorrect reverses of IRC1/IRC2" faults. 4
1 ÷ 10 IRC fault sensitivity is lowest when value 1 is set and highest when the value 10 is set.
Incor. rev. IRC
time filter [903]
IRC fault reaction period for "Incorrect reverses of IRC1/IRC2" faults. 0,100 s
0,001 s ÷ 300,000 s
High freq. encoder
[1612]
Threshold frequency from speed measurement sensor used for control
feedback by the parameter Speed source [1000] (page 58), interpteted as
electrical, not mechanical frequency.
200 Hz
Max. frequency
[111] ÷ 5000
If the fault evaluation is turned on by selecting "High frequency" in parameter Encoder
fault mode [535] (page 109), fault " E32-IRC fault (page 33)" is generated when this
frequency is exceeded.
7.8.3 FAULT ACKNOWLEDGEMENT
Group of parameters number [164]
Mode of operation after the fault and conditions settings for the converter block after a high number of faults.
MENU \ SETTINGS \ FAULTS AND WARNINGS \ FAULT ACKNOWLEDGEMENT
Name [ID] Description Def.
Fault
acknowledgement
source [165]
Setting the method of acknowledgement the fault state.
If the cause no longer exists (high current, low voltage),
the fault state ends - will be confirmed by the configured
fault confirmation method. Control panel |
