Using Channel Limited Channel Control Mode to Install Specimens
To help protect specimens and fixtures, you may want to use the Station Builder application to create a
Channel Limited Channel (CLC) control mode that you can use as the Manual Command control mode.
The CLC control mode is typically set up as displacement control with a force signal as the limit input. Once
created, you can use the Station Setup tool to set limits (typically force) to control the amount of force that
can be applied during specimen installation.
When using Manual Command set to CLC, as the force signal value enters the user-defined CLC bandwidth,
channel limiting starts to slow the actuator response. If a force limit is reached, the limiting channel prevents
further actuator movement, regardless of the displacement command.

For more information about CLC setup and tuning, see Adjustments Tab - CLC Control Modes on page 234
and About CLC Tuning on page 236.
