Technical data
The many variables in the last requirement above are most easily dealt with using
the following tables.
•
First, determine your maximum braking time ON (ON
MAX
), minimum braking time
OFF (OFF
MIN
) and load type (deceleration or overhauling load).
•
Calculate duty cycle:
•
In the appropriate table, find the column that best matches your data:
– ON
MAX
< column specification and
– Duty cycle < column specification
•
Find the row that matches your drive.
•
The minimum power rating for deceleration to zero is the value in the selected
row/column.
•
For overhauling loads, double the rating in the selected row/column, or use the
“Continuous ON” column.
