I always have to get the book for that specific drive do a little reading and you should easily figure out what you need. generally torque values come from the motor. That is asuming that you have the process requirements and just need to program your drive
this is From http://www.elec-toolbox.com
To calculate motor full-load torque, apply this formula:
T = HP x 5252 rpm
T = torque (in lb-ft) HP = horsepower 5252 = constant rpm = revolutions per minute Example: What is the FLT (Full-load torque) of a 30HP motor operating at 1725 rpm?
T = HP x 5252 rpm T = 30 x 5252 1725 T = 157,560 1725 T = 91.34 lb-ft
