Drive Control & Communication

Quick Start Instructions

Follow these Quick Start instructions to use ModBus Communications for basic network control of an 
Tmd drive. These instructions are for basic start, stop, direction and speed control of the Tmd drive. To 
download the 

Tmd product manual visit the AC Tech Technical Library at http://www.lenze-actech.com.

7.1  Initial Settings

These instructions are for basic start, stop, direction and speed control of the 

Tmd drive using modbus 

communications.

1.  For this application set Parameter C01 of the drive to 11.

2.  Set C09 to the desired network address that the Modbus master will poll. Valid Modbus addresses are 

1-247.

Tip

 - Avoid using address 1. Most Modbus devices ship with a default address of 1. As duplicate 

addressing on a Modbus network is not allowed, this can lead to conflicts when replacing and 
commissioning nodes. To avoid this, it is recommended not to set the slave address to 1.

3.  The Modbus master needs to be set to use 9600 baud. No other baud rates are supported by the TMD 

drive.

4.  The TMD series drive has the provision for a watchdog timer to monitor network communications to 

the drive. The drive’s timeout behavior is set using Parameter n22 and the timeout period is set using 
Parameter n23 as shown in Table 19.

Set n22 and n23 as appropriate for the application

5.  The drive needs to have its network data formatting set the same as the Modbus master.

a.  If the Modbus master is set to use 8 data bits, no parity and two stop bits, set c25 to 0.

b.  If the Modbus master is set to use 8 data bits, no parity and one stop bit, set c25 to 1.

c.  If the Modbus master is set to use 8 data bits, even parity and one stop bit, set c25 to 2.

d.  If the Modbus master is set to use 8 data bits, odd parity and one stop bit, set c25 to 3.
