Faults and alarms
15.2 List of faults and alarms
Cause: The serial number of the motor encoder of a synchronous motor has changed. The change was only checked for encoders
with serial number (e.g. EnDat encoders) and build-in motors (e.g. p0300 = 401) or third-party motors (p0300 = 2).
Cause 1:
- the encoder was replaced.
Cause 2:
- a third-party, built-in or linear motor was re-commissioned.
Cause 3:
- the motor with integrated and adjusted encoder was replaced.
Cause 4:
- the firmware was updated to a version that checks the encoder serial number.
Note:
With closed-loop position control, the serial number is accepted when starting the adjustment (p2507 = 2).
When the encoder is adjusted (p2507 = 3), the serial number is checked for changes and if required, the adjustment is reset
(p2507 = 1).
Proceed as follows to hide serial number monitoring:
- set the following serial numbers for the corresponding Encoder Data Set: p0441= FF, p0442 = 0, p0443 = 0, p0444 = 0,
p0445 = 0.
- parameterize F07414 as message type N (p2118, p2119).
Remedy: For causes 1, 2:
Carry out an automatic adjustment using the pole position identification routine. Acknowledge fault. Initiate the pole position
identification routine with p1990 = 1. Then check that the pole position identification routine is correctly executed.
SERVO:
If a pole position identification technique is selected in p1980, and if p0301 does not contain a motor type with an encoder
adjusted in the factory, then p1990 is automatically activated.
or
Set the adjustment via p0431. In this case, the new serial number is automatically accepted.
or
Mechanically adjust the encoder. Accept the new serial number with p0440 = 1.
For causes 3, 4:
Accept the new serial number with p0440 = 1.
F07433 Drive: Closed-loop control with encoder is not possible as the encoder has not been unparked
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The changeover to closed-loop control with encoder is not possible as the encoder has not been unparked.
Remedy: - check whether the encoder firmware supports the "parking" function (r0481.6 = 1).
- upgrade the firmware.
Note:
For long-stator motors (p3870.0 = 1), the following applies:
The encoder must have completed the unparking procedure (r3875.0 = 1) before a changeover can be made to closed-loop
control with encoder. The encoder is unparked using binector input p3876 = 0/1 signal and remains until a 0 signal in this
state.
F07434 Drive: It is not possible to change the direction of rotation with the pulses enabled
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A drive data set was selected - with the pulses enabled - which has a different parameterized direction of rotation (p1821).
It is only possible to change the motor direction of rotation using p1821 when the pulses are inhibited.
Remedy: - change over the drive data set with the pulses inhibited.
- ensure that the changeover to a drive data set does not result in the motor direction of rotation being changed (i.e. for these
drive data sets, the same value must be in p1821).
