06-15 Temperature Level Overheat (OH) Warning

Settings
 Sets the drive's internal IGBT overheat warning level. When the temperature is higher than
Pr.06-15 setting, the oH1 fault displays and the warning remains but it does not affect the drive
operation.
 Use this parameter to check the motor overheat in advance in order to take precautionary
measures to decrease the temperature and maintain the motor's normal operation.
 If you set the temperature 5ºC higher than the maximum setting value for Pr.06-15, IGBT
overheating occurs and the drive stops. Refer to Chapter 14 oH1 fault descriptions for details.
Stall Prevention Limit Level (Weak Magnetic Field Current Stall
06-16

Prevention Level)
Settings
 This parameter only works in VF, VFPG, and SVC control mode.
 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: When Pr.06-03 = 150%, Pr.06-04 = 100% and Pr.06-16 = 80%, when the operation
frequency is larger than Pr.01-01 (Base motor frequency), 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 protective curve.)
