公式トラブルシューティング手順
Message value: Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: NONE Cause: The absolute value of the speed difference from the two setpoints (p2151, p2154) and the speed actual value (r2169) exceeds the tolerance thre shold (p2163) longer than tolerated (p2164, p2166). The alarm is only enabled for p2149.0 = 1. Possible causes could be: - the load torque is greater than the torque setpoint. - when accelerating, the torque/current/power limit is reached. If the limits are not sufficient, then it is possible that the drive has been dimensioned too small. - the speed controller is inhibited (refer to p0856; refer to Kp/Tn adaptation of the speed controller). - for closed-loop torque control, the speed se tpoint does not track the speed actual value. - for active Vdc controller. - the encoder pulse number was incorrectly parameterized (p0408). The signal is not generated if the ramp-function gener ator tracking prevents the setpoint and actual speed from drifting (moving) apart. Only for vector drives: For V/f control, the overload condition is de tected as the Imax controller is active. See also: p2149 (Monitoring configuration) Remedy: - increase p2163 and/or p2166. - increase the torque/current/power limits. - enable the speed controller. - for closed-loop torque control: The speed setpoint should track the speed actual value. - correct the encoder pulse number in p0408 or mount the correct tachometer.
