Greetings folks!
New member here, but been doing automation work for just North of 25 years.
Thought I'd pop in and ask the brain-trust a question.
I have an application which is a hydraulic press retrofit using a servo-drive.
General:
PLC - 1769-L30ERM
Drive - Kinetix 350
Motor - MPL series low inertia motor
Mechanical - Tolomatic linear actuator coupled to a ram
What I'm wanting to do is emulate the operation of a hydraulic press by manipulating the output torque of the drive by temporarily writing a reduced torque value to the drive (axis.TorqueLimitPositive), performing an absolute position MAM move past the position where the the part would be properly inserted , and monitoring the axis.TorqueReference parameter feedback until a timer is done. Basically, the motor runs at that torque value, pressing on the part until it's commanded to stop and reverse, either because it reached the end of the move or times out.
My question is, will this work? Is it a conventional method for accomplishing this? Is there a better way of doing it?
Thanks in advance!
