官方故障排除步驟
Message value: Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: NONE Cause: The calculation of the jerk time Tr = MAX(p2572, p2 573) / p2574 resulted in an excessively high value so that the jerk time is internally limited to 1000 ms. Note: The alarm is also output if jerk limiting is not active. Remedy: - increase the jerk limiting (p2574). - reduce maximum acceleration or maximum deceleration (p2572, p2573).
