Miscellaneous
(BRAKE IGBT FAULT) [2]
The brake IGBT has short-circuited. This fault means
that the unit is not able to stop the brake and that,
consequently, the resistor is constant being energized.
WARNING/ALARM: 44
Encoder loss (ENCODER FAULT)
The encoder signal is interrupted from terminal
32 or 33. Check the connections.
LEDs on encoder board:
When all LEDs are ON the connection to encoder
and encoder condition are OK.
LED 403 OFF: 5 V supply missing
LED 400 OFF: Channel A or inv. A missing
or shortcircuited
LED 401 OFF: Channel B or inv. B missing
or shortcircuited
LED 402 OFF: Channel Z or inv. Z missing
or shortcircuited.
ALARM 48:
Tracking fault
The following events can generate Alarm 48:
•
Parameter 361 set too low: Extend the range
•
Wrong encoder direction: Motor goes one way,
the encoder goes the other way
•
Running in torque limit: Insufficient torque to follow
the ramp, hitting an obstruction, etc.
•
Bad PID settings: Oscillations can produce
large errors. Readjust the PID control
(Parameters 417 and 418)

Warning word 1, Extended status word
and Alarm word
Warning word 1, extended status word and alarm
word are shown on the display in Hex format. If
there are more than one warning or alarm, a sum
of all warnings or alarms will be shown.
Warning word 1, extended status word and alarm
word can also be displayed using the serial bus
in parameter 540, 541 and 538.
