Temperature Level Over-heat (oH) Warning

Settings
 If Pr. 06-15 is set to 110ºC, when the temperature reaches 110ºC, the drive stops with an IGBT
over-heat fault.
 For Frame C and above, when IGBT temperature is above Pr. 06-15 minus 15ºC, the cooling fan
enhances performance to 100%; however, when IGBT temperature is below 35ºC of Pr. 06-15
and the temperature of CAP is below 10ºC of oH2 over-heat warning (Pr. 06-51), the cooling fan
resets. The temperature 35ºC is the criterion if Pr. 06-15 is set below 35ºC.
 Stall Prevention Limit Level (Weak Magnetic Area Current Stall Prevention Level)
Settings
 Sets the over-current stall prevention level when operation frequency is larger than Pr.01-01. This
parameter only works during acceleration.
 Example: Pr. 06-03 = 150%, Pr. 06-04 = 100% and Pr. 06-16 = 80%, when the operation
frequency is larger than Pr. 01-01, the over-current stall prevention Level during acceleration is:
Pr. 06-03 × Pr. 06-16 = 150 × 80% = 120%.
 Pr. 06-16 is invalid when the over-current stall prevention activates according to Pr. 06-04 at
constant speed.
