6.1 Faultless
condition
The green LED shows the operating status (“Enable” or “Disable”) of DES.
DES in “Disable” status (DES ready): green LED flashes (flash frequency ap-
prox. 1 Hz), red LED does not shine.
DES in “Enable” status (power stage of DES is enabled): green LED shines
continually, red LED does not shine.
6.2 Faulty
condition
Error conditions are detected by DES.
The red LED shines continually in the event of error condition.
Depending on error, the green LED flashes at varying intervals.

possible errors
1
Error 0 => Hall sensor error
•
Hall sensors incorrectly wired
•
Hall sensor supply voltage incorrectly wired
•
Damaged Hall sensor in the motor
2
Error 1 => Index processing error
•
Encoder without working index channel
•
System parameter “Encoder Resolution” set incorrectly
•
Input frequency of encoder signal too high
3
Error 2 => Wrong setting of encoder resolution
•
system parameter (“encoder resolution”) set incorrectly
4
Error 3 => Hall sensor 3 not found
•
Hall sensor 3 incorrectly wired
•
Damaged Hall sensor 3 in the motor
•
System parameter “Encoder Resolution” set too low
5
Error 4 => Over current error
•
Short circuit in the motor winding
•
Power supply cannot supply enough acceleration current
•
Gain regulation loop is too high; speed regulation gains must be reduced
•
System parameter ‘’Acceleration’’ too high
•
Damaged power stage
6
Error 5 => Over voltage error
•
power supply voltage too high
•
voltage in generation mode too high
7
Error 6 => Over speed error
•
Speed in current control mode too high (> 30 000 rpm)
8
Error 7 => Supply voltage too low for operation
•
supply voltage is too low for operation
9
Error 8 => Angle detection error
•
The difference of the angle between the encoder and Hall sensors is out
of tolerance
•
interference on encoder and Hall sensor signals
12
Error 11 => Overtemperature
•
The temperature of the power stage is too high
