Setup

NOTE: These values are set at the factory and typically
do not need to be changed.
Icon Description
This enters the pump size used for calculating shot size and flow rates. The units are mm
ple if An LC1960 metering assembly (960 pump) was on the A side, 960 is the value entered.
This is the gear reduction (if any) used between the servo motor and actuator. If there is no gear box,
enter '1'.
This is the speed the actuator moves during the reload and home cycle in mm/sec.
This is the metered stroke or the distance the piston travels in the pump tube. This value is used for
calculating shot size and flow rates. For standard PR70's the value is 1.5".
This is the reload stroke or the distance the piston travels to the retracted position to reload the pump.
For standard PR70's the value is 1.0". This value may be less for thinner materials to shorten cycle
times.
This is the lead of the actuator in millimeters per motor revolution. The typical value for the PR70 is
10.
These pushbuttons choose the type of PR70, either the fixed ratio frame or the variable ratio frame.
These pushbuttons allow the pump speed to be set as a fixed value entered by the user on the
Shot/Flow screen or to be a variable speed set by a user entered voltage on an analog input in the
PLC. Note the remote speed is not active in Pressure Mode.
