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
This parameter sets the Firewire channel that the master reference is being received from.
RESET
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
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
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
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.
