Solutions Module error status values
The Solutions Module checks for various errors as shown below.
* Phase errors are detected when the error is greater than 10
o
electrical over ten consecutive one second samples.
+ These trips can be enabled/disabled by Pr x.17.
# If the terminations are not enabled on the A, B or Z inputs the wire break system will not operate. (Note that as default the Z input terminations are
disabled to disable wire break detection on this input.)
Encoder initialisation will occur when trips 1 to 8 are reset. This causes an encoder with comms to be re-initialised and auto-configuration to be
performed if selected. Ab.Servo, Fd.Servo and Fr.Servo encoders will use the UVW commutations signals for the first 120° electrical when the motor
is restarted.
It is important that a break in the connections between the drive and the position feedback device can be detected. This feature is provided either
directly or indirectly as listed below.

The differential levels of the sine and cosine waveforms are available to
the drive. The drive detects wire break if Sine

value produced by two valid waveforms with a differential peak to peak
magnitude of 0.25V (1/4 of the nominal level). This detects wire break in
the sine and cosine connections.

Wire break in the comms link is detected by a CRC or time-out error.

supply Pr x.09 and Pr x.11 and possibly Pr x.10.
