Cause: The friction characteristic is incorrect.
Alarm value (r2124, interpret decimal):
1538:
The friction torque is greater than the maximum from the upper effective torque limit (p1538) and zero.
This is the reason that the output of the friction characteristic (r3841) is limited to this value.
1539:
The friction torque is less than the minimum from the lower effective torque limit (p1539) and zero.
This is the reason that the output of the friction characteristic (r3841) is limited to this value.
3820 ... 3829:
Incorrect parameter number. The speeds entered in the parameters for the friction characteristic do
not correspond to the following condition:
0.0 < p3820 < p3821 < ... < p3829 <= p0322 or p1082, if p0322 = 0
Therefore the output of the friction characteristic (r3841) is set to zero.
3830 ... 3839:
Incorrect parameter number. The torques entered in the parameters for the friction characteristic do
not correspond to the following condition:
0 <= p3830, p3831 ... p3839 <= p0333
Therefore the output of the friction characteristic (r3841) is set to zero.

Remedy: Fulfill the conditions for the friction characteristic.
Re alarm value = 1538:
Check the upper effective torque limit (e.g. in the field weakening range).
Re alarm value = 1539:
Check the lower effective torque limit (e.g. in the field weakening range).
Re alarm value = 3820 ... 3839:
Fulfill the conditions to set the parameters of the friction characteristic.
If the motor data (e.g. the maximum speed p0322) are changed during commissioning (p0010 = 1, 3),
then the technological limits and threshold values, dependent on this, must be re-calculated by select-
ing p0340= 5).
207961 <location>Drive: Friction characteristic record activated
Message -
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The automatic friction characteristic record is activated.
The friction characteristic is recorded at the next power-on command.
Remedy: None necessary.
The alarm disappears automatically after the friction characteristic record has been successfully com-
pleted or the record is de-activated (p3845 = 0).
207963 <location>Drive: Friction characteristic record interrupted
Message Parameter: %1
value:
Drive object: SERVO, VECTOR
Reaction: OFF1
Acknowledge: IMMEDIATELY
Cause: The conditions to record the friction characteristic are not fulfilled.
Fault value (r0949, interpret decimal):
0046: Missing enable signals (r0046).
1082: The highest speed value to be approached (p3829) is greater than the maximum speed
(p1082).
1084: The highest speed value to be approached (p3829) is greater than the maximum speed (r1084,
p1083, p1085).
1087: The highest speed value to be approached (p3829) is greater than the maximum speed (r1087,
p1086, p1088).
1110: Friction characteristic record, negative direction selected (p3845) and negative direction inhib-
ited (p1110).
