５．３ Analog Input （２）Usage Instructions
Before using the Analog Input (2) function, perform gain and offset adjustment as described in thepreceding section.
Through the Analog Input (2), the input analog signal can be set to be the rotation speed command value(or frequency command value), torque command value or built-in PLC input value. The following explanation
is for when it is set as the rotation speed command value or the torque command value. For instructions
when using it as the input value to the built-in PLC, please refer to the VF66 PCTool manual.

（１）When using the input as a rotation speed command value
When using the analog input as a rotation speed command value, the inverter configuration parameters
shown in the following table must be set.

(*) This is set as a percentage with respect to the maximum rotation speed (configuration parameter A-00). For
information about configuration parameter A-00, please refer to the VF66B inverter manual.

- Set b-10 to “4”.
- Set G-03 (described in section 5.1) to a set value that matches the input signal characteristics.
・In the case of voltage input of 0 to ±10V
The rotational direction can be reversed by setting the command input voltage to a negative value. The
rotation speed command value is set as the Analog Input (2) rotation speed upper limit (G-04) when the input
is +10V. When the input is -10V, it is set as the negative value of the Analog Input (2) rotation speed upper
limit (G-04). However, it is possible to set a lower limit by setting the Analog Input (2) rotation speed lower
limit (G-05). (Figure 5.2, left)If the minimum rotation speed (A-01) is other than “0”, the rotation speedcommand absolute value is controlled to prevent falling below the minimum speed. In this case, when thecommand input voltage is around the 0V range, its behavior shows hysteresis characteristics (It will run
forward if started in the forward direction and will run in the minimum reverse speed if started in the reverse
direction) as shown in the right side of Figure 5.2.

・In the case of voltage input of 0 to 10V
The rotation speed command value is set as the Analog Input (2) rotation speed lower limit (G-05) when the
input is 0V. When the input is 10V, it is set as the Analog Input (2) rotation speed upper limit (G-04). However,this will be set to “0” if the Analog Input (2) rotation speed lower limit (G-05) has a negative value. (Figure 5.3)
If the minimum rotation speed (A-01) is other than “0”, the rotation speed command absolute value iscontrolled to prevent falling below the minimum speed. As a speed command, this only allows forward
operation. For reverse operation, a reverse operation command should be used.

・In the case of current input of 4 to 20mA:
The rotation speed command value is set as the Analog Input (2) rotation speed lower limit (G-05) when the
input is 4mA. When the input is 20mA, it is set as the Analog Input (2) rotation speed upper limit (G-04).
However, this will be set to “0” if the Analog Input (2) rotation speed lower limit (G-05) has a negative value.
(Figure 5.4) If the minimum rotation speed (A-01) is other than “0”, the rotation speed command absolutevalue is controlled to prevent falling below the minimum speed. As a speed command, this only allows
forward operation. For reverse operation, a reverse operation command should be used.

Chapter ７ DeviceNet Communication function
This section explains electric wiring and termination attention of trunk line and drop line in connection of
DeviceNet.

７．１ Connection of DeviceNet
In connection of DeviceNet, terminating resistors are required on each end of the trunk line. Drop lines
as long as 6 m (20 feet) each are permitted, allowing one or more nodes to be attached. DeviceNetallows branching structures only on the drop line.

Figure 7.1

The total amount of trunk line allowable on the network depends upon the data rate and the type ofcable (thick or thin) used. The cable distance between any two points in the cable system must notexceed the Maximum Cable Distance allowed for the baud rate. For trunk lines constructed of only one
type of cable, refer to Table 7.1-a to determine the Maximum Cable Distance based on the data rate andthe type of cable used.
Cable distance between two points includes both trunk line cable length and drop line cable lengththat exists between the two points.

Data RateDeviceNet allows the use of either thick or thin cable to be used to construct trunk lines.
DeviceNet also allows a combination of both types of cable to be used on the same network. To
determine the maximum cable distance with a mix of both thick and thin cable, use Table 7.1-b.
Table 7.1-b
Data Rate

Computation expression
L thick + 5×L thin = 500m

250k bps

L thick + 2.5×L thin = 250m

500k bps

L thick + L thin = 100m

L thick is length of thick cable. L thin is length of thin cable.

Drop line length is the longest cable distance of those measured from the tap on the trunk line to eachof the transceivers of the nodes on the drop line. This distance includes any dropline

cable whichmight be permanently attached to the device. The total amount of drop line allowable on the network
depends upon the data rate. Refer to the following Table 7.1-c when determining the number andlength of drop lines.

７．２ Cable
Thick Cable：This cable consists of two shielded pairs twisted on a common axis with a drain wire in
the center covered with an overall braid shield and is commonly used as trunk line whenlength is important.
Thin Cable ：Thin Cable is smaller and more flexible than Thick Cable. It is commonly used for droplines, but can also be used, for shorter distances, as trunk line.
Listed below are general requirements for the DeviceNet Thick/Thin Cable. Other types of external
insulation and/or jacketing are allowable provided that internal construction and electricalcharacteristics adhere to the cable specifications.
・ One twisted signal pair {#18*(Thick Cable)/#24*(Thin Cable)} ; blue/white・ One twisted power pair {#15*(Thick Cable)/#22*(Thin Cable)} ; black/red
・ Separate aluminized mylar shields around power pair and signal pair・ Overall foil/braid shield with drain wire {#18*(Thick Cable)/ #22*(Thin Cable)} ; bare**・ High speed (Vp = 75% min), low loss, low distortion, data pair (to keep propagation delays
to a minimum)・ 8 amp (Thick Cable)/ 3 amp (Thin Cable) maximum current capacity

・ PVC insulation on power pair・ Industrial temperature range
・ High flexibility* #** means AWG indication of a power size. #15 = 1.652mm2, #18 = 0.8233mm2, #22 =0.3243mm2, #24 = 0.2047mm2** The drain wire connects the shields within the cable and serves as a means to terminate theshield into the connector.

７．３ Terminating Resistors
DeviceNet requires a terminating resistor to be installed at each end of the trunk. The resistor
requirements are:・ 121 ohm
・ 1 % Metal Film・ 1/4 Watt
Important: Terminating resistors should never be included in nodes. Inclusion of thiscapability could easily lead to a network with improper termination (too high or
too low an impedance) potentially causing failure. For example, removal of anode, which includes a terminating resistor, could result in network failure.
Important: Terminating resistors should not be installed at the end of a drop line, only at
the two ends of the trunk line.

７．４ Connectors
All connectors must support five conductors, which accommodate a signal pair, power pair, and adrain wire. DeviceNet supports the following types of connectors allowing both sealed and open media
solutions:
Open Connectors
・ Pluggable
・ Hard wired
Sealed Connectors
・ Mini-style connector
・ Micro-style connector
Important: All nodes attaching to DeviceNet with a connector must have male pins. Thisapplies to sealed and unsealed connectors and all nodes whether they are
consuming or providing power.
Important: Whatever connector solution is chosen it is mandatory that devices can beremoved without severing or disturbing the network.

７．５ Device Taps
Device taps provide points of attachment onto the trunk line. Devices can be connected to the network
either directly to the tap or with a drop line. Taps also provide easy removal of a device without
disrupting network operation.
Taps are defined for:・ sealed (with and without drop lines)
・ open (with and without drop lines)

７．６ DeviceNet Communication function Setting
The Analog input (2) to the terminals on DNET66-Z can be used as the input value to the rotation speedcommand value (or frequency command value), torque command value, and built –in PLC function by analog
input (2) function.
For usage of DeviceNet communication function correctly, the correct VF66 Inverter parameter setting as
mentioned below is required. Please see the VF66 Inverter instruction manual together. Furthermore, for thebuilt-in PLC function, please see VF66 PC Tool manual.
