fails, parameter 48 will remain at a 3 so that another autotune will be carried out the next
time the drive is run.
This determines the boost level for the fixed boost characteristic when parameter 48 is
set to 2.
OFF - the functionality of terminal 13 is determined by the setting of parameter 05.
ON - terminal 13 is set-up as a motor thermistor input
Connect the motor thermistor between 0V and terminal 13.
Trip resistance: 3kΩ
Reset resistance: 1k8
The drive will not trip if the motor thermistor goes short circuit
When terminal 13 is set up as a motor thermistor, it is not affected by the logic
select (parameter 34).
The following parameters are used for setting up an external mechanical brake.
If the brake function is to be used, parameter 29 should be set accordingly before
any parameters are programmed. This is because parameter 29 will set all
parameters back to their default values.
Brake set-up parameters
The following parameters become active when parameter 29 is set to br.EU or br.US.
Sets the zero speed threshold
Sets the threshold level for the motor current
Sets the hysteresis level on the motor current
Sets the logic delay on the digital output
