The following simultaneous contradictory settings: C6-05 is greater than 6
and C6-04 is greater than C6-03 (carrier frequency lower limit is greater than
the upper limit). If C6-05 is less than or equal to 6, the drive operates at
C6-03.
Upper and lower limits between C6-02 and C6-05 contradict each other.

Scaling for the pulse train monitor is set to 0 (H6-07 = 0) while H6-06 is not
set to 101, 102, 105, or 116.

Torque Control in enabled (d5-01 = 1) while the Speed/Torque Control
switch function is assigned to a digital input (H1-oo = 71).
Either Torque Control is enabled by d5-01 = 1, the or Speed/Torque Control
switch is assigned to a digital input H1-oo = 71, while at the same time:
• Feed Forward is enabled (n5-01 = 1), or
• Droop Control is enabled (b7-01 ≠ 0), or
• Intelligent Stall Prevention or Intelligent Stall Prevention 2 is enabled
(L3-04 = 2 or 5), or
• A digital input is set for the power KEB 1 or KEB 2 (H1-oo = 7A or 7B)

In AOLV/PM, the automatically calculated energy saving coefficients are
out of the allowable range.

One of the following errors occurred while online tuning was enabled in OLV
(A1-02 = 2):
• E2-02 was set below 30% of the original default value
• E2-06 was set below 50% of the original default value
• E2-03 = 0

6.6 Operator Programming Errors
Correct the settings for E1-04, E1-06, E1-07, E1-09, and E1-11 (for motor
2, correct E3-04, E3-06, E3-07, E3-09, and E3-11).
Error Name
Carrier Frequency Setting Error
Correct the setting for the carrier frequency.
Possible Solutions
Correct the parameter settings.
Error Name
Pulse Monitor Selection Error
Incorrect setting of monitor selection for pulse train (H6-06).
Possible Solutions
Change scaling for the pulse train monitor or set H6-06 to 101, 102, 105,
or 116.
Error Name
Torque Control Setting Error
Parameters settings that are not allowed in combination with Torque
Control have been set.
Possible Solutions
Correct the parameter settings.
Error Name
Energy Savings Constants Error
Possible Solutions
Check and correct the motor data in E5 parameters.
Error Name
Online Tuning Parameter Setting Error
Parameters controlling online tuning are not set correctly.
Possible Solutions
Set E2-02, E2-03, and E2-06 to the correct values.
