在西门子上找到的国外的专家回答的答案，我看了一下。但参数MD36520一般都是按照标准的125%来设置的。还是奇怪，为什么只有RESET时才出现该报警！

找到的回答如下：
1016 “系统错误代码550010 ”报警原因

Here the information out of DOCONWEB
36520 DES_VELO_LIMIT % Threshold for setpoint velocity monitoring DOUBLE NEW CONF。
Maximum permissible setpoint velocity in percent of the maximum axis/spindle velocity.
With $MA_DES_VELO_LIMIT, the position setpoint is monitored for abrupt
changes. If the permissible limit value is exceeded, alarm 1016 error code550010 is output.
With axes, this machine data refers to $MA_MAX_AX_VELO.
With spindles, the MD refers to the smaller one of the set velocities
$MA_GEAR_STEP_MAX_VELO_LIMIT of the current gear stage or
$MA_SPIND_VELO_LIMIT.
