官方故障排除步骤
Message value: Drive object: SERVO, VECTOR Reaction: OFF2 Acknowledge: IMMEDIATELY (POWER ON) Cause: One of the following values is stored in p9700 or has been entered offline: 87 or 208. This is the reason that the system is attempting to copy the SI parameters from the Control Unit to the Motor Module during booting. However, no safety function is selected on the Control Unit (p9501 = 0, p9601 = 0) which is why the copy operation is rejected. Note: This fault does not result in a safety stop response. See also: p9700 (SI Motion copy function) Remedy: - set p9700 = 0. - check p9501and p9601 and correct if necessary. - start the copy function again by entering the appropriate value in p9700.
