• System configuration
• Operation Process
1) Position control by the unit (CS1W-HCA12-V1):
A speed command is issued to the servo driver with the analog
output. The servo driver feeds back the absolute position infor-
mation with the absolute encoder input. Using the feedback, po-
sition control is executed (through the speed command output)
following SPED or ACC instructions on the ladder program of the
unit.
2) Pressure control by the unit (speed control and torque limit):
Reaching a certain position (position for pressure control) caus-
es the unit to output a speed and a torque limit command for the
speed control and torque limit. The pressure control (clamping
etc) is executed after the unit converts the analog inputs (load
cell, strain gauge, etc) from the pressure sensor to the analog
outputs (torque limit by the speed command and torque limit out-
put) for the servo driver.
3) Position control by the unit
Once the operation (molding, etc) is completed, a speed com-
mand output from the unit returns the mechanical system to its
origin.
