6. Control Functions and Parameter Settings
6-52
(2) The multi-pump control, uses the PID function. Refer to the explanation given for the
parameters B43-0 to 4. The PID is enabled setting PIDEN function to ON.
The multi-pump control is always carried out in the remote mode (LCL OFF), through
RUN, RRUN commands.
(3) Refer to section (1) and set the parameters B44-1 to 3.
(4) By using the setting interlock function (C20 = 0 to 3), the VAT2000 run/stop can be
controlled by the pressure command input (FSV, FSI). In this case, the signal
command (RUN-R.RUN) should be always ON.
Refer to the explanation on C20-0 to 3

Traverse run
Traverse function allows operation in which the frequency fluctuates with the pattern shown
below. This is effective for evenly winding up the thread on a bobbin in a weaving system.

1) Traverse run
(1) To carry out traverse run, turn the sequence command PROG ON.
(2) If the sequence command RUN or R RUN is turned ON, the machine will accelerate at
the cushion (A01-0) at the center frequency (speed), and then traverse run will start.
(3) When RUN (or R RUN) is turned OFF, the machine will decelerate to a stop with the
cushion (A01-1).
(4) During traverse operation, the conventional cushion, S-ramp, overcurrent limit (OCL)
and overvoltage limit (OVL) will not function. However, these will function while
accelerating or decelerating during start or stop.
(5) The traverse center frequency (rotation speed) can be selected with C02-1.
C02-1 = 1: Analog fixed (C07-4)
= 2: Panel fixed (B45-0)
= 3: Sequence (S0,S1)
When using traverse run, set B11-8 to 1 (selection mode setting: binary mode).
If C02-1 is set to 1, the setting from a external source selected with C07-4 will be the
center frequency (speed).
When C02-1 is set to 3, and traverse run is being carried out, the operations (2) and
(3) described below will take place through the sequence command S0 and S1.
