Modbus TCP/IP Specication
Section 1. Overview
The DYN5 servo drive optioned with Modbus TCP/IP communication allows the servo drive to
be fully operated on a Modbus TCP/IP network. The DYN5 servo drive acts as Server (Slave)
device and exchanges data with a Client (Master) device. Through this network, the Client has
full access and control of the servo drive including:
• Reading and Writing servo drive parameters
• Reading servo motor Position/Speed/Current/Torque
• Reading servo drive Status
• Sending Position/Speed/Torque command
♦ Compatible Model Numbers
The DYN5 servo drive with the below model numbers are optioned with Modbus TCP/IP com-
munication. Note that the servo drive optioned with Modbus TCP/IP still has base Pulse/Analog/
RS232 capability it the user wishes to use these control methods.
For additional infomration regarding Modbus TCP/IP network and protocol specication, please
refer to Modbus Organization at www.modbus.org.

Section 2. Network Connection
For general DYN5 servo drive operation and wiring instructions, refer to DYN5 servo drive in-
struction manual Manual# DYN5MS-ZM1.
Connector JP5A and JP5B are used for the Modbus TCP/IP interface. Both connectors are stan-
dard RJ45.
The DYN5 servo drive supports daisy-chain topology, JP5A is used for input, JP5B is used for
output. The last servo drive on the chain should have JP5B terminated with the JP5 Terminator
(Part# CN5-JP5-TMD1). If only 1 servo drive is on the network, the terminator still needs to be
connected to JP5B, with JP5A connected to the Client (Master).

(1) Download and install DMMDRV5 software.
(2) Download and install Modbus Poll software (www.modbustools.com). Modbus Poll is a Mod-
bus TCP/IP master (Client) simulator software for PC computer.
(3) Check PC ethernet port TCP/IPv4 settings. This is needed to set and match with the servo
drive IP address. For this example, the PC IP address is set to 192.168.0.10 and subnet mask
255.255.255.0
(4) Connect all components to servo drive as above diagram (A) Wiring and Connections. Apply
power to servo drive.
(5) Establish connection between DMMDRV5 program and DYN5 servo drive. See Appendix A
for connection setup instructions.
(6) Open the Servo Setting module. Select Position Servo Mode 1 . Select Ethernet Com-
mand Input Mode (Modbus TCP/IP) 2 . Note no matter the operation command from Modbus
TCP/IP, the servo drive should be set into Position Sero Mode here. The servo drive will internal-
ly switch between Position/Speed/Torque servo modes according to the command received from
Modbus TCP/IP. Set the servo drive IP address within the network of the PC IP address 3 . In
this example, the servo drive IP address is set to 192.168.0.20. Set GEAR_NUM to 16384 4 .
(7) Click Save All to save new settings into servo drive 5 . Power cycle servo drive - remove
power from both L1/L2 and R/S/T. Wait 30 seconds, then apply power again.
The DYN5 servo drive is now correctly setup for Modbus TCP/IP.

Modbus TCP/IP Specication
Check servo drive ethernet connectivity using Ping test on PC.
(1) Open the PC Command Prompt.
(2) Type “ping AAA.AAA.AAA.AAA” where AAA.AAA.AAA.AAA is the servo drive IP address set
in Section 3.1 Step. 6.
(3) Check that a reply is received back from the servo drive. This conrms the servo drive is in
Ethernet mode and IP address is set correctly.
(4) If reply is not received from servo drive, check all connections and settings in Section 3.1.
3.2 Ping (ICMP) Test

Modbus TCP/IP Specication
Check Modbus TCP/IP connectivity using Modbus Poll software. Modbus Poll software turns the
PC into Modbus Client (master) used to test servo drive communication.
(1) Open the Modbus Poll software.
(2) Click Connection->Connect. Select Modbus TCP/IP connection. Input servo drive IP ad-
dress. Make sure server port is set to 502 for standard Modbus TCP port. Make sure IP protocol
is set to IPV4. Click OK. Check that connection is established and registers are read from servo
drive.
3.3 Modbus Poll Test
192.168.0.20
(4) See Section 4. for servo drive Modbus Register specication. The default Modbus Poll pro-
gram reads 10 registers from address 0x00 to 0x09. The registers are read once a second and
the “Tx” counter on top increments each time a read is successful.

(6) Select both 0x1D and 0x1E register displays and right click, select Format->32-bit signed-
>big endian. This will automatically combine the two 16-bit Modbus registers into one 32-bit
signed data showing full motor position on 0x1D display location. The position displayed should
be 0 or close to 0 as the motor position drifts slightly at steady state 1 . If the servo drive is set
to Absolute mode, the readout position will be single-turn or multi-turn absolute position.
(7) Recall in Section 3.1, Step 6, GEAR_NUM parameter was set to to 16384. This sets the
position command ratio so that a prole position command of 65536 will move the motor 1 revo-
lution (for motors equipped with 16-bit resolution encoders). See Appendix B for Prole Position
Command trajectory details.
(8) Send a command to move the motor 1 revolution. Select Functions->16 Write Registers.
Relative Prole position command is register 0x17 and 0x18.
(9) Set to settings as below and Click Send to send a position command of 65536 and check that
the motor moves exactly 1 revolution Clockwise. The position readout from 0x0D (Step 6) should
now read 65536 to indicate the motor has rotated exactly 1 revolution.
(5) (Relative Prole Position command example) Set Modbus Poll so it reads from register
containing servo motor position. Click Setup->Read/Write Denition. 32-bit servo motor position
is contained in registers 0x1D and 0x1E. Set to below setting and click OK. Note Slave ID
number does not matter.
