Temperature level overheat (OH)

Depending on
the model
power
● 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. See Chapter 14 oH1 fault descriptions for details.

Stall prevention limit level
(Weak magnetic field current stall
prevention level)
0 to 100% (see Pr.06-03–Pr.06-04)
100
● 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).
● Example: When Pr.06-03 = 150 %, Pr.06-04 = 100 % and Pr.06-16 = 80 %.
The over-current stall prevention level during acceleration:
Pr.06-03 * Pr.06-16 = 150 x 80 % = 120 %.
The over-current stall prevention level during operation:
Pr.06-04 * Pr.06-16 = 100 x 80 % = 80 %.
