Overview of Alarms
Cause: More than one encoder with identical component number is assigned to a single drive data
set. In one drive data set, it is not permissible that identical encoders are operated together.
Fault value (r0949, decimal):
1000*first identical encoder + 100*second identical encoder + drive data set.
Example:
Fault value = 1203 means:
In drive data set 3, the first (refer to p0187[3]) and second encoder (refer to p0188[3]) are
identical.
See also: p0141, p0187, p0188, p0189
Remedy: Assign the drive data set to different encoders.
See also: p0141, p0187, p0188, p0189
207511 <location>Drive: Enc. used multiple
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: Each encoder may only be assigned to one drive and within a drive must - in each drive
data set - either always be encoder 1, always encoder 2 or always encoder 3. This unique
assignment has been violated.
Fault value (r0949, decimal):
The two parameters in coded form, that refer to the same component number.
First parameter:
Index: First and second decimal position
Parameter number: Third decimal position (1 for p0187, 2 for p0188, 3 for p0189)
Drive number: Fourth and fifth decimal position
Second parameter:
Index: Sixth and seventh decimal position
Parameter number: Eighth decimal position (1 for p0187, 2 for p0188, 3 for p0189)
Drive number: Ninth and tenth decimal position
See also: p0141
Remedy: Correct the double use of a component number using the two parameters coded in the fault
value.
207512 <location>Drive: Encoder data set changeover not permissible
Reaction: NONE
Acknowledge: NONE
Cause: A changeover of the encoder data set is prepared using p0187, p0188 or p0189. For this
firmware release, an encoder data set changeover is not supported. Commissioning can
only be exited with the correct parameterization.
Alarm value (r2124, decimal):
Parameter number with incorrect indices (p0187, p0188 or p0189).
See also: p0187, p0188, p0189
Remedy: The selectors to the encoder data sets (p0187, p0188, p0189) must, for all data sets, point
to the same encoder data set.
The following must apply:
p0187[0] = p0187[1] = ... = p0187[n]
p0188[0] = p0188[1] = ... = p0188[n]
p0189[0] = p0189[1] = ... = p0189[n]
207514 <location>Drive: Data structure does not correspond to the interface
module
Reaction: NONE
Acknowledge: NONE
