Heatsink Overheat
oH
The temperature of the heatsink exceeded the overheat pre-alarm level set to L8-02. Default value
for L8-02 is determined by drive capacity (o2-04).
Heatsink Overheat
oH1
The temperature of the heatsink exceeded the drive overheat level. The overheat level is determined
by drive capacity (o2-04).
Motor Overheat Alarm (PTC thermistor input)
oH3
• The motor overheat signal to analog input terminal A1 or A2 exceeded the alarm detection level.
• Detection requires multi-function analog input H3-02 or H3-10 be set to "E".
Motor Overheat Fault (PTC thermistor input)
oH4
• The motor overheat signal to analog input terminal A1 or A2 exceeded the fault detection level.
• Detection requires that multi-function analog input H3-02 or H3-10 = "E".
