BS Controller for AC SERVO PRESS
Instruction Manual Ver1.08
BS-M3A-1B
- 61 -
The regeneration electric power which occurs by rapid slowdown is changed
into heat by regeneration resistance. In BS Configurator, a monitor is possible
for the rate of regeneration load. If the rate of regeneration load exceeds 85%,
it will become the alarm of the abnormalities in regeneration (caution). There
are two methods in avoiding the abnormalities in regeneration. The first is the
method of lowering regeneration frequency.、The second is the method of using
more nearly mass regeneration resistance.
Although it is the warning of fault regeneration as MR-J3A when the
rate of regeneration load exceeds 85%, by BS controller, warning is also treated
as alarm.
Lowering regeneration frequency
Although there are a method of lengthening slowdown time, and a method of
taking long operation pause time in order to lower regeneration frequency ,in
all a cycle time becomes long.
The larger regeneration option is prepared by Mitsubishi Electric than the
regeneration resistance built-in MR-J3A. Refer to the technical data of MR-J3A
for the details of a regeneration option.
When it corresponds to the regeneration of high frequency by the
regeneration option, it is necessary to consider the temperature rise in a
control board. I ask measure, such as attaching a cooling device so that the
temperature in a control box may not exceed 50 degrees C, of you.
