Code 207995: <location>Drive: Pole posi tion identification not successful

Message value: %1 Drive object: SERVO Reaction: OFF2 Acknowledge: IMMEDIATELY Cause: The pole position identificati on routine was unsuccessful. Fault value (r0949, interpret decimal): 1: No current is established. 2: The starting current is not zero. 3: The selected max. distance was exceeded (p1981). 4x: The measuring signal does not permit a clear evaluation. 5: The max. current was exceeded during the measurement. 6: The current measurement must be re-calibrated. 7x: The Sensor Module does not support t he pole position identification routine. 70... 79: Only for inter nal Siemens troubleshooting. 8: The pole position identification routine curr ent required is greater than the max. current. 9: The set pole position identification routine current is zero. 10: Data set changeover during t he pole position identification. 11: The encoder adjustment to determine the commutation angle (p1990 = 1) and the encoder without zero mark is not finely synchroni zed or does not have any valid data. 100: Motion-based pole position ident ification, 1st and 2nd measurement different. Motor locked or current (p1993) too low. 101: Motion-based position position identification, insu fficient motion, motor locked or current (p1993) too low. 102: Motion-based pole position ident ification, brake is being used and is closed. The motion-based position position identification in conj unction with the brake is not permitted. 103: Motion-based pole position identification without encoder. 104: Motion-based pole position ident ification, speed actual value not zero after stabilizing time. Note: x = 0... 9 Remedy: Re fault value = 1: Check the motor connection and DC link voltage. For the following parameters, set practical values that are not zero (p0325, p0329). Re fault value = 3: Increase the max. distance (p1981). Reduce the currents for the pole positi on identification routine (p0325, p0329). Stop the motor in order to carry out the pole position identification routine. Re fault value = 40... 49: Increase the currents for the pole posit ion identification routine (p0325, p0329). Stop the motor in order to carry out the pole position identification routine. Select another technique for pole position identification routine (p1980). Use another motor, absolute encoder or Hall sensors. Re fault value = 5: Reduce the currents for the pole positi on identification routine (p0325, p0329). Re fault value = 6: Re-calibrate the Motor Module. Re fault value = 7x: Upgrade the software in the Sensor Module. Re fault value = 8: Reduce the currents for the pole position identification routine (p0329, p0325, p1993). The power unit cannot provide the necessary pole position identification routine current (p0209 < p0329, p0325, p1993), replace the power unit by a power unit with a higher max. current. SINAMICS-Alarms Re fault value = 9: Enter a value not equal to zero in the pole position identification routine current (p0329, p0325, p1993). Re fault value = 10: Do not initiate a data set changeover during the pole position identification. Re fault value = 11: - for incremental encoders without commutation with zero mark (p0404.15 = 0), it does not make sense to adjust the encoder to determine the commuta tion angle (p1990 = 1). In this case, the function should be de-selected (p1990 = 0) or, for an encoder with suitable zero mark, commutation with zero mark should be selected (p0404.15 = 1). - for absolute encoders, only adjust the encoder to determine the commutation angle (p1990 = 1) if the encoder supplies commutation information and is finely synchronized (p1992.8 = 1 and p1992.10 = 1). The encoder is possibly parked, de-activated (p0145), not ready to operate or signals a fault condition. - deselect the encoder adjustment to deter mine the commutation angle (set p1990 to 0). Re fault value = 100, 101: Check and ensure that the motor is free to move. Increase the current for motion-based pole position identification (p1993). Re fault value = 102: If the motor is to be operated with a brake: Select a different technique to identify the pole position (p1980). If the motor can be operated without a brake: Open the brake (p1215 = 2). Re fault value = 103: The motion-based pole position identification can only be carried out using an encoder. Connect an encoder or select another technique for pol e position identification routine (p1980). Re fault value = 104: Pole position identification, increase the smoothing time, motion-based (p1997). Pole position identification, increase the rise time, motion-based (p1994). Pole position identification, c heck the gain, motion-based (p1995). Pole position identificati on, check the integral time, motion-based (p1996).
