L8-55 Internal DB
TransistorProtection
(045F)
0 : Disable
Disables braking transistor protection.
Use this setting, if enabling the braking transistor can cause an rF [Braking Resistor Fault] in these conditions:
• With a regenerative converter, for example D1000.
• With a regenerative unit, for example R1000.
• When connecting braking resistor options to the drive, for example CDBR units.
• Without an internal braking transistor.
1 : Protection Enabled
Protects internal braking transistor when using a braking transistor or optional braking resistors.
These models have a built-in braking transistor:
• 2004 to 2138
• 4002 to 4168

Note:
If this value is too small, it can cause incorrect detection of STPo. If this value is too large, the drive will not detect STPo.

V/f CL-V/f OLV CLV AOLV
Sets the detection level for STPo [Motor Step-Out Detected] related to the ACR integral value.
V/f CL-V/f OLV CLV AOLV
Sets the length of time until the drive detects STPo after it is more than the value of L8-51 [STPo I
Detection Level].
V/f CL-V/f OLV CLV AOLV
Sets the Id deviation detection function for STPo [Motor Step-Out Detected].
V/f CL-V/f OLV CLV AOLV
Sets the protection function for the internal braking transistor.
V/f CL-V/f OLV CLV AOLV
Sets the length time that the acceleration stall prevention function can continue to operate before
the drive detects an STPo [Motor Step-Out Detected].
