NOTE: 

If no TMS7 starter is configured to the specific 
slave address, no response will be received by the 

host. The host software timeout should be set to a 
minimum of 250 ms. 

 

NOTE: 
Slave address must be two digit, addresses less 

than 10 must have a leading zero (0).

Each command, status or data request is a 3 byte string as 
detailed below. Invalid command/request strings cause the 

TMS7 to respond with a NAK (15h). 
 

Start 

B10 

Initiates a start. 

Stop 

B12 

Initiates a stop 

Reset 

B14 

Resets a trip state 

Coast to 
stop 

B16 

Initiates an immediate removal of 
voltage from the motor. Any soft 

settings are ignored. 

 
 

Status 

C10 

Requests the configuration status of the 

TMS7. 

Status_1 

C12 

Requests the operational status of the 

TMS7. 

Trip 

C14 

Requests the trip status of the TMS7.

8 =

9 = 

Undercurrent trip 

10 =

overtemperature 

11 = 

Invalid motor connection 

 

Current 

D10 

Requests motor current. The data is 4 
byte decimal ASCII. Minimum value 

0000, Maximum value 9999 Amps. 

Temp 

D12 

Requests the calculated value of the 
motor thermal model as a % of Motor 

Thermal Capacity. The data is 4 byte 
decimal ASCII. Minimum value 0000%. 
Trip point 0105%. 

 
Each command string sent to and from the TMS7 includes a 

check sum. The form used is the Longitudinal Redundancy 
Check (LRC) in ASCII hex. This is an 8-bit binary number 
represented and transmitted as two ASCII hexadecimal 

characters. 
To calculate LRC: 

1. 

Sum all ASCII bytes 

2. 

Mod 256 

3. 

2's complement 

4. 

ASCII convert

To verify a received message containing an LRC; 

1. 

Convert the last two bytes of message from ASCII to 
binary. 

2. 

Left shift 2

nd

 to last byte 4 bits. 

3. 

Add this result to the last byte to get the binary LRC. 

4. 

Add up all the bytes of the message, except the last two. 

5. 

Add the binary LRC. 

6. 

The least significant byte should be zero.
