故障现象描述:
1.主轴无转动 / PPU 屏幕提主轴,且屏中无报警提示。
2.屏幕有轴数值,实际主不动,且屏幕报警提示。
3.主轴转不稳定(时快时慢)
诊断步骤
检查 PPU 后侧主轴X54
1.接口是松动或损坏
2.启动主后用万用表测量 X54 的引脚 1
9,观察是有电压输出
检查 主轴与频器的连接缆是否完
如果上检查之后故障然存在,则很可能是系统 (PPU) ,
进行更或维修
若故障为:屏幕主轴转速数值,实际主轴不动
检查机数据 MD30130 / MD30240 / MD30134 / MD32250 / MD32260 /
MD35150 的设置否正确
1.MD30130=1 / MD30240=2
2.MD30134 主轴输出(可在 02 之间设)
0 性,1 / 2 单极(由实情况确定)
3.MD32250=100 / MD32260与实际电机额定转速持一

检查所使用的主轴变频器是出现故障
情况2
若故障:主轴度不稳定(时慢)

Spindle
fault
Fault description:
1. The spindle cannot move, the PPU screen shows the waiting for spindle
signal and the screen has no alarm prompt.
2. The screen has spindle values, but the actual spindle cannot move and
the screen has no alarm prompt.
3. The spindle angle of rotation is not steady (varies during rotation).
If the fault is
The spindle cannot move, the PPU screen shows
the waiting for spindle signal.
If the fault is
Th
e screen has spindle values, but the actual
spindle cannot move.
If the fault is
The spindle angle of rotation is not steady (varies
during rotation)
Check whether there is an interference between the connections (it is
better to separate thicker and thinner wires).
Check the interface of X54 on the back of the PPU
1.Whether the interface is loose.
2.Whether the connections have a faulty contact.
Please ch
eck whether the connection of the spindle converter is
loose or whether the converter is damaged.
Please check whether the PPU is in the program
test state.
1. Whether the indicator light of the
Program test
key on MCP is on or not (it
should not be on).
2. Whether the
PRT
indicator on the PPU
screen is activated or not (it should not be acti-
Use the diagnostic steps of
Case1
mentioned
above to check the
spindle if the fault still
exists.
Check the settings of machine data MD30200 (spindle is set to 1 if it has an
encoder, otherwise 0).
Check the spindle interface of X54 on the back of the PPU
1. Whether the interface is loose or damaged.
2. Measure pins 1 and 9 of X54 with a multi-meter after
starting the spindle, then observe if there is voltage output.
Check whether the connection cable between the PP
U,
spindle and encoder is good.
Check whether the settings of machine data MD30130/MD30240/MD30134/
MD32250/MD32260/MD35150 are correct.
1. MD30130 = 1 / MD30240 = 2
2. MD30134 - spindle output polarity (set between 0 ~ 2 )
0-dual polarity, 1/2-single polarity (depends on the actual situation)
3. MD32250 = 100 / MD32260, it is consistent with actual motor rated
speed.
Check whether the spindle converter sh
ows a fault or not.
Replacement and maintenance are necessary if the fault still exists after
the above inspection, because it is probable that the PPU is damaged.
