YASKAWA SIEP YAIP1U 01C AC Drive - P1000 Technical Manual
• Cycle power to the drive.
• If the problem continues, replace the control board or the entire drive. Contact Yaskawa or a Yaskawa
representative for instructions on replacing the control board.
Option Card Error Occurred at Option Port CN5-C
Refer to the option manual for details.
Heatsink Overheat
oH
The heatsink temperature exceeded the overheat pre-alarm level set to L8-02. The default value for L8-02
is determined by drive model selection (o2-04).
• Check the temperature surrounding the drive. Verify temperature is within drive specifications.
• Improve the air circulation within the enclosure panel.
• Install a fan or air conditioner to cool the surrounding area.
• Remove anything near the drive that might be producing excessive heat.
• Measure the output current.
• Decrease the load.
• Lower the carrier frequency selection (C6-02).
• Replace the cooling fan.
• After replacing the cooling fan, set parameter o4-03 to 0 to reset the cooling fan maintenance.
Overheat 1 (Heatsink Overheat)
oH1
The heatsink temperature exceeded the drive overheat level. Overheat level is determined by drive
capacity (o2-04).
• Check the temperature surrounding the drive.
• Improve the air circulation within the enclosure panel.
• Install a fan or air conditioner to cool the surrounding area.
• Remove anything near the drive that might be producing excessive heat.
• Measure the output current.
• Lower the carrier frequency selection (C6-02).
• Reduce the load.
Motor Overheat (NTC Input)
oH5
The motor temperature exceeded the level set to L1-16 (or L1-18 for motor 2)
• Reduce the load.
• Check the ambient temperature.
Motor Overload
oL1
The electronic motor overload protection tripped
Reduce the load.
Increase the acceleration and deceleration times (C1-01 through C1-04).
