Heat Sink Over-heat (OH1) Warning
Default: 105.0
Settings 0.0–110.0°C
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)
Default: 50
Settings 0–100% (Refer to Pr.06-03, Pr.06-04)
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.
