About Channel Limited Channel (CLC) Control Modes
Use a channel limited channels (CLC) control mode for specimen installation and
removal. Before CLC control modes can be tuned, they must first be defined in
the Station Builder application.
A CLC control mode requires an active and a limiting feedback signal:
• The active feedback signal controls the actuator’s movement. It is normally
the channel’s displacement feedback signal.
• The limiting feedback signal limits the actuator’s force. It is normally the
channel’s force feedback signal.
When CLC is used as the control mode, the controller will not allow the actuator
to exceed limits set for either the active or limiting feedback signals:
• Interlocks can trip if the actuator’s active (displacement) feedback signal
exceeds limits set for it in the Station Setup window’s Limits tab.
• The actuator’s limiting (force) feedback signal cannot exceed limits set for it
in the Station Setup window’s Adjustment tab.
