11- 03 Carrier Frequency auto reduction due to temperature rise
Range
【0】:Disable
【1】:Enable
If inverter (heat sink) temperature rises above 80°C the carrier frequency is reduced by 4K.
If the temperature falls below less than 70°C, carrier frequency is restore to the value of 11-01.
Temperature can be displayed by setting parameter 12-00=04000.

Use S Curve parameters where a smooth acceleration or deceleration action is required,
this will prevent possible damage to driven machines by sudden acceleration/deceleration.

Note:
Regardless of the stall prevention period, actual acceleration and deceleration time =preset
acceleration / deceleration time + S curve time.
Please set the required individual S curve times in the parameters (11-04~11-07).
When S curve time (11-04~11-07) is set as 0, the S curve function is disabled.
The calculation of S curve time is based on the Maximum output frequency of motor
(01-02), Please refer to the parameters (00-14/00-15/00-16/00-17).
