力士乐TDM系列伺服电机编码器故障F822代码修理手册

F822 Motor Encoder Failure: Signal too Small
电机编码器故障：信号太小

Description:说明：
The motor encoder signals are monitored.
监测电机编码器信号。
If the signal amplitudes as measured via AK1 and AK2 are outside of the allowable region between Uss = 12.0V and Uss = 18.0 V, then the error message appears. 如果通过AK1和AK2测量的信号幅度在Uss=12.0V和Uss=18.0V之间的允许范围之外，则出现错误消息。
The drive becomes torque-free and an optional brake is immediately activated.
驱动器无扭矩，可选制动器立即启动。

Cause:原因：
1. Defective feedback cable.
反馈电缆有缺陷。
2. Defective feedback.
反馈有缺陷。

Remedy:解决措施：
For 1. Check the feedback cable.
检查反馈电缆。
Lay the power cables separate from the feedback cable.
将电源电缆与反馈电缆分开放置。
The cable shield must be connected to the drive controller.
电缆屏蔽必须连接到驱动器控制器。
(See also project reference of the drive control).
