Description
This parameter sets the maximum amplitude of the current for dynamic braking. AXIS#.DBILIMIT can only be set manually when AXIS#.MOTOR.DISAUTOSET index (28) is set to 1. Setting AXIS#.MOTOR.AUTOSET to 0 does not make AXIS#.DBILIMIT writeable.
-
- If the motor or drive current is in foldback before entering dynamic brake mode, the actual current limit might be less than AXIS#.DBILIMIT when dynamic braking starts. The current will be limited to the minimum of AXIS#.DBILIMIT and AXIS#.IL.IFOLD . Once the foldback current recovers, AXIS#.DBILIMIT will be the enforced current limit.
Example
Setting AXIS#.DBILIMIT to 2 limits the dynamic brake current to 2 Arms.

| Bug fix | 02-08-00-000 | The bug caused AXIS#.DBILIMIT to be reset to its default value under some conditions. The fix involved making the parameter read only by default and calculated from motor parameters. |
