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.
