9.7 Adjust Value
9.7.1 Servo PID Manual Tuning
Located under Additional Functions/Set value/Adjust Value, it allows the user to test and
configure the servo PID and block modes.
PID Coefficients
Proportional-Action Coefficient
1:
Proportional-action coefficient for both moving
directions.
Derivative-Action Coefficient 1: Derivative-action coefficient for both moving
directions.
Integral-Action Coefficient 1: Integral-action coefficient for both moving directions.
Block Modes
Target Mode: Sets the desired mode for the block. The input
parameters of the block in conjunction with the state
of the block are used to determine if the block can
achieve the requested target mode. The automatic
modes used in this profile are Auto and RCAS. The
manual modes are LO and Man. In O/S mode, the
normal algorithm is no longer executed.
Actual Mode: Indicates the current mode of operation the block is
able to achieve.
Working SP: Process variable from the analog output block after
characterization, FLOP and reverse acting
(SIGNAL_ACTION) in POSITION_UNITS.
Working Position: Position value (Hall sensor value) in engineering
units defined in the POSITION_UNITS parameter.
