Temperature Level Overheat (OH) Warning
Default: 105.0
Settings 0.0–110.0°C
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 capacitor oH warning level (Pr.06-51), the cooling fan
resets. The temperature 35ºC is the criterion if Pr.06-15 is set below 35ºC.
06-16
Stall Prevention Limit Level
Default:
Settings 230V / 460V models: 0–100%
(refer to Pr.06-03)
100
575V / 690V models: 0–100%
(refer to Pr.06-03)
50
Sets the over-current stall prevention level when the motor’s operation frequency is larger than
Pr.01-01 (base frequency). 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 lowest over-current stall prevention level during acceleration is:
Pr.06-03 × Pr.06-16 = 150 × 80% = 120%. (Refer to Pr.06-03 diagram for the protection curve.)
Pr.06-16 is invalid when the over-current stall prevention activates according to Pr.06-04 at constant
speed.
