- reduce max. speed (p1082).
- suppress meas. (p1959).
Re fault value = 193:
- the motor has moved through more than 5° electrical (r0093). Lock motor rotor at one of these pole
position angles (r0093): 90 °, 210 ° or 330 ° (+/-5 °) and then start identification.
Re fault value = 194:
- switch out all supplementary torques (e.g. CI: p1511).
- for hanging/suspended axes: Lock motor rotor at one of these pole position angles (r0093): 90 °, 210
° or 330 ° (+/-1 °) and then start identification.
Re fault value = 195:
- de-select closed-loop torque control (p1300 = 21 or 20, or set the signal source in p1501 to a 0 sig-
nal).
Re fault value = 200, 201:
- set pulse frequency to 0.5 * current controller frequency (e.g. 4 kHz for a current controller clock cycle
of 125 us).
- reduce cable length between Motor Module and motor.
- read-out measured values (r1950, r1951) and therefore determine suitable values for p1952, p1953
according to your own estimation.
207991 <location>Drive: Motor data identification activated
Message -
value:
Drive object: SERVO
Reaction: NONE
Acknowledge: NONE
Cause: The motor data ident. routine is activated.
The motor data identification routine is carried out at the next power-on command.
See also: p1910, p1960
Remedy: None necessary.
The alarm automatically disappears after the motor data identification routine has been successfully
completed or for the setting p1910 = 0 or p1960 = 0.
207991 <location>Drive: Motor data identification activated
Message -
value:
Drive object: VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The motor data ident. routine is activated.
The motor data identification routine is carried out at the next power-on command.
See also: p1910
Remedy: None necessary.
The alarm automatically disappears after the motor data identification routine has been successfully
completed or for the setting p1900 = 0.
207993 <location>Drive: Incorrect direction of rotation of the field or encoder
actual value inversion
Message -
value:
Drive object: SERVO
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: Either the direction of the rotating field or the encoder actual value has an incorrect sign. The motor
data identification automatically changed the actual value inversion (p0410) in order to correct the
control sense. This can result in a direction of rotation change. To acknowledge this fault, the correct-
ness of the direction of rotation must first be acknowledged with p1910 = -2.
