PLL (PHASE LOCKED LOOP)
The phase locked loop function block allows the drive to ride through short disturbances to the
supply voltage, frequency or phase and provides immunity to waveform distortion.

PROFILED GAIN
This function block may be used to profile the proportional gain input to the PID block.
PROFILED GAIN
Parameter
Tag
Range
PROP. GAIN
404
0.0 to 100.0
The nominal gain prior to profiling.
MIN PROFILE GAIN
474
0.00 to 100.00 %
This expresses the minimum gain required at minimum diameter (core) as a percentage of the (maximum) P gain at full diameter (100%), when
MODE > 0.
DIAMETER
709
0.00 to 100.00 %
The actual measured diameter. If appropriate, this may be connected to the DIAMETER output parameter in the DIAMETER CALC function block.
MIN DIAMETER
710
0.00 to 100.00 %
Set to the minimum core diameter (normally the empty core diameter) as a percentage of the maximum roll diameter. If appropriate, this may be
connected to the MIN DIAMETER parameter in the DIAMETER CALC function block.
D-100 Programming
PROFILED GAIN
Parameter
Tag
Range
MODE
473
0 to 4
This determines the shape of the proportional gain profile. The higher the setting, the steeper the curve of the profiled gain.
For Mode = 0, Profiled Gain = constant = P.
For Mode = 1, Profiled Gain = A * (diameter - min diameter) + B.
For Mode = 2, Profiled Gain = A * (diameter - min diameter)^2 + B.
For Mode = 3, Profiled Gain = A * (diameter - min diameter)^3 + B.
For Mode = 4, Profiled Gain = A * (diameter - min diameter)^4 + B.
PROFILED GAIN
475
.x
The proportional gain after profiling by a profiler block which varies the gain versus diameter. This is primarily to be used with Speed Profiled
Winders for compensation against varying diameter and therefore inertia.
• When MODE is not ZERO (see above) this overrides the P gain above.
• When MODE = 0, then PROFILED GAIN = PROP. GAIN.

Programming D-103
When EXTERNAL RESET is set TRUE, the raise/lower output resets to RESET VALUE (default = 0.00%).
When RAISE INPUT is TRUE, the output increases at INCREASE RATE. The output cannot exceed MAX VALUE.
The reverse is true when LOWER INPUT is TRUE: LOWER INPUT reduces the output at DECREASE RATE. The output cannot drop below MIN
VALUE.
The ramp is held at its last value when the RAISE and LOWER INPUT are removed.
Setting both RAISE INPUT and LOWER INPUT to TRUE at the same time creates a ramp hold condition.
If MIN VALUE is greater than MAX VALUE the output is forced to zero.

RAMPS
The RAMPS parameters set the shape and duration of the ramp used for starting and
changing speeds.
NOTE The STOP RATES function block contains a separate deceleration rate for
controlled stopping of the drive.
By default the inputs are ANIN 3 (A4) for a ramped speed input, and DIGIN 2 (C7) to switch
RAMP HOLD. The input signal to the block is clamped by MIN SPEED, which sets the minimum
ramp input speed when the drive is enabled. The default output connection is to SPEED LOOP::
SETPOINT 3.
RAMP INPUT is internally routed to the JOG/SLACK function block to be modified as determined
by the JOG inputs. The RAMPS block then shapes the signal to produce the RAMP OUTPUT
signal.
The RAMPING output becomes TRUE when the absolute value of the difference between RAMP OUTPUT and the JOG/SLACK function block
output exceeds RAMPING THRESH.
RAMP ACCEL TIME and RAMP DECEL TIME set the acceleration and deceleration times taken for input changes. % S-RAMP adds a "S" shaped
section to the linear ramp. When set to 0.00%, the ramp will be linear. As the percentage is increased, 350% of the S-RAMP time is added to the linear
ramp creating more gradual starting and stopping. The formula for the actual ramp time is shown below. Ramp time is the value of parameters RAMP
ACCEL TIME or RAMP DECEL TIME.
Actual Ramp Time = RAMP TIME x (3.5 x % S-RAMP/100 + 1)
RAMP HOLD stops the ramp from changing. When DIGIN 2 (C7) is ON, the ramp stays at the last ramp value.
The reset signal can have two sources, a RUN signal or an external reset signal. When AUTO RESET is ENABLED, the ramp resets whenever a Run
signal is given at terminal C3. Connecting a digital input to EXTERNAL RESET allows an external source to reset the ramp.

RAMP HOLD

-105.00 to 105.00 %

% S-RAMP
266
0.00 to 100.00 %
Percentage of ramp with S-shaped rate of change. A value of zero is equivalent to a linear ramp. Changing this value affects the ramp times.
RAMPING THRESH.
286
0.00 to 100.00 %
Ramping flag threshold level. The threshold is used to detect whether the ramp is active.
AUTO RESET
287
DISABLED / ENABLED
When ENABLED, the ramp is reset whenever SYSTEM RESET is TRUE. (SYSTEM RESET Tag 374 is an internal flag that is set TRUE for one
cycle after the Speed/Current loop is enabled, i.e. every time the drive is started).
EXTERNAL RESET
288
DISABLED / ENABLED
When ENABLED, the ramp is reset to RESET VALUE. EXTERNAL RESET does not depend on AUTO RESET for its operation.
RESET VALUE
422
-300.00 to 300.00 %
The ramp output value at power-up, or when the ramp is reset. In order to catch a spinning load smoothly (`bumpless transfer’) connect SPEED
FEEDBACK Tag No. 62 (source) to RESET VALUE Tag No. 422 (destination).
