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.
