2. Installation Into Inverter
The installation procedure and points of caution are as described below.
(1)Remove the inverter unit's front cover.
CAUTION
1. Wait at least 20 minutes after turning the power OFF before starting work. Make sure that the
displays on the operation panel have gone out before removing the cover.
2. After removing the cover, confirm that the “CHARGE” LED on the unit has gone out.
Also check that the voltage between terminals L+1 or L+2 and L- is 15V or less before starting
the inspections.
(Check with the “CHARGE” LED if the unit is not provided with the L- terminal.)
(2)If the other option PCB is installed onto the position for option II on the control PCB cover,
install this PCB onto the position for option III.
Refer to Fig. 2-1.
(3)When wiring to TB1 use AWG26 to 16 (0.14 to 1.5mm2) for the wires.
Wires should be terminated correctly, with suitable crimp terminals or ferrules.
Pass the wires through the cable connection hole on the inverter unit and then connect.
CAUTION
1. Observe the cautions listed in Fig. 3-1 and Section 2-4 in the VAT2000 Instruction Manual
(PCST-3251) when wiring.

3-1. Connection and setting procedure
(1) Connection
The parallel data input connection is shown in Fig. 3-1.
The parallel data is input from CN1. CN1 is a DDK FRC2-C26L11-0L.
The flat cable (FRC2-AA26-10S) must be provided by the user.
CAUTION
1. The cable length must be 30m or less.
2. The external power can be supplied from the flat cable; but if the cable length is 2m or more,
supply the power from TB1.
The wires that can be used for TB1 are AWG26 to 16 (0.14 to 1.5mm2).
If the flat cable cannot be passed through the inverter unit's cable connection hole, remove the
plate of the cable connection hole.
In this case, the protective structure will be IP00.

(2)Setting procedure
1) Decide the circuit format and data format.
2) Decide the circuit format (open collector/open emitter) with W1. (Fig. 3-5).
3) Turn ON the power, Set the parameter C02-0 to 2 (parallel fixed). (Refer to Fig. 5-9 in the
VAT2000 Instruction Manual (PCST-3251).)
4) Set the data input mode, circuit format, and parallel data format in C32-0 to C32-2.
Note) Set the A05-2 setting value to 1 to cancel the hardware option display skip when setting
the C32-0 to C32-2 parameters.
(The default value is display skip.)
3. Parallel Data Input

3-2. Data input mode selection and signal specifications
The following three methods can be used for the parallel input data input method.
1) 16-bit with strobe
2) 8-bit multiplexed with strobe
3) 16-bit sample
These methods are selected with parameter No. C32-0.
(1) 16-bit with strobe (C32-0 = 1)
The 16-bit data (D0 to 15) is loaded with the rising edge of the strobe (STB).

(2) 8-bit multiplexed with strobe (C32-0 = 2)
The 16-bit data is divided into the low-order 8-bit and high-order 8-bit with the LSB signal, and
each is loaded with the rising edge of the strobe (STB).

3-3. Signal logic and circuit format selection
(1) Signal logic selection (D0 ~ D15)
Dn = 1 when the contact connected to D0 to D15 is ON (closed circuit), or Dn = 1 when the
contact is OFF (open circuit) can be selected with parameter No. C32-1. (Appendix Table 3)
(2)Signal common selection (W1)
Setting of all signal commons to EX0 or EX24 can be selected with the W1 setting.
The sequence output method open collector and open emitter can both be corresponded to with
this.
