The [Regen Power Lim] is programmed as a percentage of the rated power. The
mechanical energy that is transformed into electrical power during a deceleration or
overhauling load condition is clamped at this level. Without the proper limit, a bus
overvoltage may occur.
When using the bus regulator [Regen Power Lim] can be left at factory default, –
50%. When using dynamic braking or a regenerative supply, [Regen Power Lim]
can be set to the most negative limit possible (–800%). When the user has dynamic
braking or regenerative supply, but wishes to limit the power to the dynamic brake
or regenerative supply, [Regen Power Lim] can be set to a level specified by the
user.
