Heat Sink Over-heat (OH1) Warning

Settings
 If Pr.06-15 is set to 110°C, when the temperature reaches 110°C, the drive stops with an IGBT
over-heat fault.
 For Frame C and above, when IGBT temperature is above Pr.06-15 minus 15°C, the cooling fan
enhances performance to 100%; however, when IGBT temperature is below 35°C of Pr.06-15
and the temperature of CAP is below 10°C of oH2 over-heat warning (Pr.06-51), the cooling fan
resets. The temperature 35°C is the criterion if Pr.06-15 is set below to 35°C.
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 is as below:
Over-current stall prevention level during acceleration = Pr.06-03 × Pr.06-16 = 150 × 80% =
120%.
Over-current stall prevention level during operation = Pr.06-04 × Pr.06-16 = 100 × 80% = 80%
 Pr.06-16 is invalid when the over-current stall prevention activates according to Pr.06-04 at
constant speed.
