tracing and limit
current failure
Err40
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

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

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
