Parker 690+ series - PHASE CONTROL

Programming Your Application 1-69
690+ Series Frequency Inverter
PHASE CONTROL
This is the principal phase function block
and controls the error generation as well
as the feed-forward calculation.

Parameter Descriptions
RESET (TOTAL)
Range: FALSE / TRUE
Total Reset, disables both the SPEED OUPUT and PHASE LOOP, see POSITION ENABLE.
POSITION ENABLE
Range: FALSE / TRUE
The position enable input. Enables the operation of the accumulator. If set FALSE, then the
accumulator is set to zero and any phase information is reset. See also RESET (TOTAL).
SPEED INPUT
Range: -300.00 to 300.00
Input to the speed feed-forward calculator, to obtain good phase locking it is important that this
input is used. The speed input will usually be the master line speed, this input should be set such
that the slave will follow the master even with the phase loop disabled.
INVERT SPEED OP
Range: FALSE / TRUE
Invert the speed output.
GEARING A
Range: -30000 to 30000
Gearing allows the slave to run at a ratio of the master speed / position.

FDFWD SCALE
Range: -300.00 to 300.00
Scale position feed-forward. Scaled with PHASE CONFIG::MAX SPEED. This feed forward
works only for position setpoint changes and is designed to reduce the following error of the
system by predicting the torque required to accelerate the motor.
OUTPUT SCALE
Range: 0.00 to 300.00
Scales the position output.
INVERT OUTPUT
Range: FALSE / TRUE
Inverts the position output.
