官方故障排除步驟
Message value: Drive object: SERVO, VECTOR Reaction: OFF2 Acknowledge: IMMEDIATELY Cause: A drive data set was selected - with the pulses enabled - which has a different parameterized direction of rotation (p1821). It is only possible to change the mo tor direction of rotation usi ng p1821 when the pulses are inhibited. Remedy: - change over the drive data set with the pulses inhibited. - ensure that the changeover to a drive data set does not result in the motor direction of rotation being changed (i.e. for these drive data sets, the same value must be in p1821). See also: p1821
