Message value: %1 Drive object: VECTOR Reaction: OFF1 (NONE, OFF2) Acknowledge: IMMEDIATELY Cause: A fault has occurred during the encoder test. Fault value (r0949, interpret decimal): 1: The speed did not reach a steady-state condition. 2: The speed setpoint was not able to be approached as the minimum limiting is active. 3: The speed setpoint was not able to be approached as the suppression (skip) bandwidth is active. 4: The speed setpoint was not able to be appr oached as the maximum limiting is active. 5: The encoder does not supply a signal. 6: Incorrect polarity. 7: Incorrect pulse number. 8: Noise in the encoder signal or speed controller unstable. 9: Voltage Sensing Module (VSM) incorrectly connected. SINAMICS-Alarms Remedy: Re fault value = 1: - check the motor parameters. - carry out a motor data identification routine (p1910). - if required, reduce the dynamic factor (p1967 < 25 %). Re fault value = 2: - adapt the speed setpoint (p1965) or adapt the minimum limit (p1080). Re fault value = 3: - adapt the speed setpoint (p1965) or suppre ssion (skip) bandwidths (p1091... p1094, p1101). Re fault value = 4: - adapt the speed setpoint (p1965) or maximum limit (p1082, p1083 and p1086). Re fault value = 5: - check the encoder connection. If required, replace the encoder. Re fault value = 6: - check the connection assignment of the enc oder cable. Adapt the polarity (p0410). Re fault value = 7: - adapt the pulse number (p0408). Re fault value = 8: - check the encoder connection and encoder cable. It is possible that there is a problem associated with the ground connection. - reduce the dynamic response of the s peed controller (p1460, p1462 and p1470, p1472). Re fault value = 9: - check the connections of the Voltage Sensing Module (VSM). Note: The encoder test can be switc hed out (disabled) using p1959.0. See also: p1959
