L8-39: Reduced Carrier Frequency
Determines value the carrier frequency is reduced to by the torque boost function.
L8-55: Internal Braking Transistor Protection
Enables or disables protection for the internal braking transistor.
Setting 0: Disabled
Disable braking transistor protection when not using the internal braking transistor, including the following instances:
When using a regen converter such as DC5.
When using a regen unit such as RC5.
When using external braking transistor options like CDBR units.
When using the drive in common DC bus applications and the internal braking chopper is not installed.
Enabling L8-55 under such conditions can incorrectly trigger a braking transistor fault (rF).
Setting 1: Enabled
The following models come with a built-in braking transistor:
•CIMR-L2A0018 to 2A0115
•CIMR-L4A0009 to 4A0060
Enable L8-55 when connecting a braking resistor or a braking resistor unit to the drive built-in braking transistor.
Overload Tolerance for Internal Braking Transistor
Below, Figure 5.40 show the overload tolerance level for the drive’s built-in braking transistor.
