Minimum Velocity Control Limit
(FCC45, SCC45, TCC45, INC45, FOC45, SOC45, TOC45, OSC45,)
The value in this word corresponds to the minimum controllable velocity
during the respective profile. The QDC module uses this word with the
Selected Velocity Valve, Output for Minimum (word 47) below. The QDC
module expects this velocity when setting the selected velocity valve to the
percentage output you enter in word 47.
We entered zero on corresponding worksheets.
Maximum Velocity Control Limit
(FCC46, SCC46, TCC46, INC46, FOC46, SOC46, TOC46, OSC46)
The value in this word corresponds to the maximum controllable velocity
during the respective profile. The QDC module uses this word with the
Selected Velocity Valve, Output for Maximum (word 48) below. The QDC
module expects this velocity when setting the selected velocity valve to the
percentage output you enter in word 48.
Enter the maximum ram (screw) or clamp speed per your OEM
specifications on corresponding worksheets.
Selected Velocity Valve, Output for Minimum
(FCC47, SCC47, TCC47, INC47, FOC47, SOC47, TOC47, OSC47)
The QDC module uses this word with the Minimum Velocity Control
Limit (word 45) above. Enter the %-signal output that the QDC module
uses to drive the selected velocity valve for minimum profile velocity. The
QDC expects a velocity equal to word 45 when setting the selected
velocity valve to this percentage output.
The QDC module uses this setpoint to drive the selected velocity valve
when attempting to attain zero ram (screw) or clamp velocity. It should
drive the selected velocity valve to a spool position that prohibits any
hydraulic flow.
