Remedy: If you wish to operate a motor once with one motor encoder and then another time with the other motor
encoder, then you must set up two different MDSs, in which the motor data are the same.
Example:
p0186[0] = 0, p0187[0] = 0
p0186[0] = 1, p0187[0] = 1
207518 <location>Drive: Motor data set changeover incorrectly parameterized
Message %1
value:
Drive object: SERVO, TM41, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The system has identified that two motor data sets were incorrectly parameterized.
Parameter r0313 (calculated from p0314, p0310, p0311), r0315 and p1982 may only have different
values if the motor data sets are assigned different motors. p0827 is used to assign the motors
and/contactors.
It is not possible to toggle between motor data sets.
Alarm value (r2124, interpret hexadecimal):
xxxxyyyy:
xxxx: First DDS with assigned MDS, yyyy: Second DDS with assigned MDS
Remedy: Correct the parameterization of the motor data sets.
207519 <location>Drive: Motor changeover incorrectly parameterized
Message %1
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: With the setting p0833.0 = 1, a motor changeover via the application is selected. This is the reason
that p0827 must have different values in the appropriate motor data set.
Alarm value (r2124, interpret hexadecimal):
xxxxyyyy:
xxxx: First MDS, yyyy: Second MDS
Remedy: - parameterize the appropriate motor data sets differently (p0827).
- select the setting p0833.0 = 0 (motor changeover via the drive).
207520 <location>Drive: Motor cannot be changed over
Message %1
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The motor cannot be changed over.
Alarm value (r2124, interpret decimal):
1:
The contactor for the motor that is presently active cannot be opened, because for a synchronous
motor, the speed (r0063) is greater than the speed at the start of field weakening (p3048). As long as
r0063 > p0348, the current in the motor does not decay in spite of the pulses being suppressed.
2:
The "contactor opened" feedback signal was not detected within 1 s.
3:
The "contactor closed" feedback signal was not detected within 1 s.
Remedy: Re alarm value = 1:
Set the speed lower than the speed at the start of field weakening (r0063 < p0348).
Re alarm value = 2, 3:
Check the feedback signals of the contactor involved.
