AC890PX AC Drive
FIREWIRE REF
SETUP:: PHASE CONTROL::FIREWIRE REF
Performance Level = ADVANCED : CLOSED-LOOP VEC Motor Control Mode only.
The FireWire option card (Option B) must be fitted to the drive.
This block processes Virtual Master commands received over Firewire communications, producing position, speed and acceleration references to be
used by the control loops, when Firewire is selected as the reference source (Firewire Comms Sel is TRUE in Comms Control block).
Parameter Descriptions
CHANNEL PREF: 119.01 Default: 0 Range: 0 to 62
This parameter sets the Firewire channel that the master reference is being received from.
RESET PREF: 119.02 Default: FALSE Range: FALSE / TRUE
This parameter resets the Outputs to zero. Note if this is set TRUE whilst the drive is running following the Firewire Reference, then the drive will
decelerate to zero speed on the System Ramp.
INVERT PREF: 119.03 Default: FALSE Range: FALSE / TRUE
This parameter inverts the master reference. Note that this inversion does not take place locally in the drive, so the master and local diagnostics
below will always be in the same direction.
GEAR RATIO A PREF: 119.04 Default: 1000000 Range: -2000000000 to 2000000000
This parameter provides a Gear Ratio A/B (see GEAR RATIO B) inserted between master reference input and Firewire Ref outputs. Output = Gear
ratio A / Gear Ratio B * Master Input.
GEAR RATIO B
PREF: 119.05 Default: 1000000 Range: -2000000000 to 2000000000
This parameter provides a Gear Ratio A/B (see GEAR RATIO A) inserted between master reference input and Firewire Ref outputs. Output = Gear
ratio A / Gear Ratio B * Master Input.
POSITION OUTPUT PREF: 119.06 Default: —.xxxx deg Range: —.xxxx deg
This diagnostic shows the position demand in load mechanical degrees.
SPEED OUTPUT
PREF: 119.07 Default: —.xx Hz Range: —.xx Hz
This diagnostic shows the speed demand in load mechanical Hz (rev/s).
