A07943 Sync-line-drive: Synchronization not permitted
Drive object: VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: Synchronization is not permitted.
Alarm value (r2124, interpret decimal):
1300: The control mode (p1300) has not been set to sensorless closed-loop speed control or V/f characteristic.
1910: Motor data identification activated.
1960: Speed controller optimization activated.
1990: Encoder adjustment activated.
3801: Voltage Sensing Module (VSM) not found.
3845: Friction characteristic record activated.
Remedy: Fulfill the conditions for the line-drive synchronization.
Re alarm value = 1300:
Set the control mode (p1300) to sensorless closed-loop speed control (p1300 = 20) or V/f characteristic (p1300 = 0
... 19).
Re alarm value = 1910:
Exit the motor data identification routine (p1910).
Re alarm value = 1960:
Exist the speed controller optimization routine (p1960).
Re alarm value = 1990:
Exit the encoder adjustment (p1990).
Re alarm value = 3801:
Connect-up a Voltage Sensing Module (VSM) and when connecting to an adjacent drive object ensure that the drive
objects have the same basis clock cycle.
Re alarm value = 3845:
Exit the friction characteristic record (p3845).
F07950 (A) Drive: Incorrect motor parameter
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: - the motor parameters were incorrectly entered while commissioning (e.g. p0300 = 0, no motor)
The braking resistor (p6811) has still not been parameterized - commissioning cannot be completed.
Fault value (r0949, interpret decimal):
The parameter number involved.

(Rated motor current), p0307 (Rated motor power), p0310 (Rated motor frequency), p0311 (Rated motor speed),
p0314 (Motor pole pair number), p0315 (Motor pole pair width), p0316 (Motor torque constant), p0320 (Motor rated
magnetization current/short-circuit current), p0322 (Maximum motor speed), p0323 (Maximum motor current)
Remedy: Compare the motor data with the rating plate data and if required, correct.

circuit current), p0322 (Maximum motor speed), p0323 (Maximum motor current)
Reaction upon A: NONE
Acknowl. upon A: NONE
F07955 Drive: Motor has been changed
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The code number of the actual motor with DRIVE-CLiQ does not match the saved number.
Fault value (r0949, interpret decimal):
Number of the incorrect parameter.
See also: p0301 (Motor code number selection), r0302 (Motor code number of motor with DRIVE-CLiQ)
