Cause: The condition to plot the friction characteristic are not fulfilled.
Fault value (r0949, decimal):
0046: Missing enable signals (r0046).
0840: OFF1 (p0840) is selected before the friction characteristic has been completely
plotted.
1082: The highest speed value to be approached (p3829) is greater than the maximum
speed (p1082).
1110: Friction characteristic plot, negative direction of rotation has be selected (p3845) and
the negative direction of rotation is inhibited (p1110).
1111: Friction characteristic plot, positive direction of rotation has be selected (p3845) and
the positive direction of rotation is inhibited (p1111).
1198: Friction characteristic plot selected (p3845 > 0) and the negative direction of rotation
(p1110) and positive (p1111) are inhibited (r1198).
1300: The control mode (p1300) has not been set to closed-loop speed control.
1755: For sensorless closed-loop control (p1300 = 20), the lowest speed value to be
approached (p3820) is less than or equal to the changeover speed, open-loop controlled
operation (p1755).
1910: Motor data identification activated.
1960: Speed controller optimization activated.
3820 - 3829: Speed (p382x) cannot be approached.
3840: Friction characteristic incorrect.
3845: Friction characteristic plot de-selected.
Remedy: Fulfill the conditions to plot the friction characteristic.
Re fault value = 0046:
Establish missing enable signals.
Re fault value = 0840:
Select OFF1 (p0840) only after the friction characteristic plot has been completed.
Re fault value = 1082:
Select the highest speed value to be approached (p3829) less than or equal to the
maximum speed (p1082).
Re fault value = 1110:
Select the frequency characteristic plot, positive direction of rotation (p3845).
Re fault value = 1111:
Select the frequency characteristic plot, negative direction of rotation (p3845).
Re fault value = 1198:
Enable the permitted direction of rotation (p1110, p1111, r1198).
Re fault value = 1300:
Set the control mode (p1300) on the closed-loop speed control (p1300 = 20, 21).
Re fault value = 1755:
For sensorless closed-loop speed control (p1300 = 20) select the lowest speed value to be
approached (p3820) greater than the changeover speed of open-loop controlled operation
(p1755).
Re fault value = 1910:
Exit the motor data identification routine (p1910).
Re fault value = 1960:
Exist the speed controller optimization routine (p1960).
Re fault value 3820 - 3829:
- check the load at speed p382x.
- check the speed signal (r0063) for oscillation at speed p382x. If required, check the speed
controller settings.
Re fault value = 3840:
Make the friction characteristic error-free (p3820 - p3829, p3830 - p3839, p3840).
Re fault value = 3845:
Activate the friction characteristic plot (p3845).
