5.1 故障报警及对策 Failure alarm and policies
故障原因排查
Failure reason one by one check
故障处理对策
Failure treatment policies
1
、变频器运行电流小于
P9-64 Frequency
converter running current lower than P9-64
1
、确认负载是否脱离或
P9-
64
、
P9-65
参数设置是否符合 实际运行
工况
Confirm whether load separated or
whether P9-64, P9-65 parameter setting
accordance with actual running working
condition
运行时PID 反馈丢失
故障 PID feedback
loss failure during
running
h PID
反馈小于
PA-26
设定值
PID feedback less
than PA-26 setting value
1
、检查
PID
反馈信号或设置
PA-26 为一个合适值 Check PID feedback
signal or set PA-26 as one suitable value
逐波限流 故障 Wave
tracing and limit
current failure
1
、 负载是否过大或发生电机堵转
Whether too
big load or happen motor blocked
2、 变频器选型偏小 Smaller frequency
converter device model select
1、 减小负载并检査电机及机械 情况
Reduce load and check the motor and
mechanical situation
2
、 选用功率等级更大的变频器
Select
more bigger power grade frequency
converter
运行时切换 电机故
障 Shift motor failure
during running
1、在变频器运行过程中通过端子更 改当前电
机选择 Modify current motor select through
terminal during frequency converter running
1、变频器停机后再进行电机切 换操作
Process motor shift operation after
frequency converter stop machine
电机过温 故障 Motor
over temperature
failure
1、 温度传感器接线松动 Temperature sensor
wiring loosen
2、 电机温度过高 Too high temperature motor
1、 检测温度传感器接线并排除 故障
Test temperature sensor wiring and solve
the failure
2
、 降低载频或釆取其它散热措 施对电
机进行散热处理 Reduce carriage
frequency or adopt other heat radiation
actions to process heat radiation of motor
初始位置 错误 Initial
position error
1
、电机参数与实际偏差太大
Too big motor
parameter and actual tolerance
1、重新确认电机参数是否正确， 重点
关注额定电流是否设定偏小
Confirm
again whether motor parameter correct,
pay attention at focus on whether lower
rated current setting
