[求助] 随时间变化的位移约束求解问题

采用如下命令流定义随时间变化的正弦位移载荷，会产生如下错误代码很是费解啊，求高手解答:
*** ERROR ***                         CP =    158.828 TIME= 23:24:33
Present time -4.999999923E-05 is less than or equal to the previous
time 0 in a transient analysis.

*** ERROR ***                         CP =    159.156 TIME= 23:24:47
The step data was checked and there were errors found.
  Please check output or errors file ( D:\ANSYS anli\default.err ) for
messages.

*** WARNING ***                      CP =    160.484 TIME= 23:24:49
Input time should be greater than zero.

*** ERROR ***                         CP =    161.969 TIME= 23:24:51
Present time -8.660253949E-05 is less than or equal to the previous
time 0 in a transient analysis.

命令流如下:

!***************表数组赋值***********************
*DIM,LOAD,TABLE,7,1,1,Time,dispaacement,
dt=1/60
PI=3.1415926

LOAD(0,0,0)=1

*DO,I,1,7,1
LOAD(I,0,1)=(I-1)*dt
*ENDDO

*DO,I,1,7,1
LOAD(I,1,1)=-0.0001*SIN(10*PI*(I-1)*dt)
