The Difference Between A6 and T6 Series Servo Motors

The A6 series servo motor is a new high-performance servo product launched by STPPERONLINE. It can easily and efficiently meet the various requirements of automated production applications. It is easy to use and achieves an excellent balance between performance and cost. The A6 series supports Pulse, Modbus 485, EtherCAT and
PROFINET control.

This series is divided into three types:

● A6-RS (supports pulse and Modbus 485)
● A6-EC (supports EtherCAT)
● A6-PN (supports PROFINET)

The A6-RS series and T6-RS series servo motor kits are very similar in function. Below we will introduce their differences in detail based on a number of parameters:


Control Method

A6-RS supports pulse signal control (maximum input frequency 4MHz), RS485 communication control, and analog voltage control. A6-EC series supports EtherCAT communication control, and A6-PN supports PROFINET communication control; while the T6 series only supports pulse signal control ( Maximum input frequency 500kHz), RS485 communication control.

A6 series servo products have diverse control methods and strong flexibility, and their pulse input frequency is superior to T6.

Encoder

The A6 series uses a 17-bit single-turn absolute encoder, which can also be used as a multi-turn absolute encoder by using the AS7-C-ENC075-BAT-3.0 cable with a battery box.
The T6-RS series is divided into two types of encoders, one is a 17-bit incremental magnetic encoder and the other is a 23-bit absolute magnetic encoder (please note: only by using the CEAST1M5-2 line with battery box cable, it can be used as an absolute encoder).

Debug Cable and Software

First of all, in terms of debugging cables, A6 uses standard TYPE-C data cables. This kind of cable harness is very easy to obtain, so STEPPERONLINE does not provide it, but we recommend that you refer to the article about how to choose Type-C cable when purchasing.

T6 uses a special cable with RS232 network cable terminal. Because it is a customized model, STEPPERONLINE is provided with the product for free.
Secondly, from the comparison of the debugging software used, the A6 series servo supports one-click auto-tuning, while the T6 does not currently support it. Moreover, A6’s debugging software is more convenient to operate, the interface layout is clearer, and the user experience is better.

Digital Input and Output Signals

A6 has 8 DI input signal points and 5 double-ended DO output signal points, allowing you to freely set the various functions you need (such as status display, JOG trial operation, etc.); the input signal of T6 also supports these functions, but T6 has only 4 input signal points, 2 single-ended outputs, and 1 double-ended output point, so A6 has high flexibility in the allocation of different functions.

Storage and Usage Environment

A6: Storage at -40℃~+70℃, operating environment temperature is 0~+55℃ (performance will be derated by approximately 10% for every 5℃ increase above 45℃);
T6: -20℃~+80℃ storage, use ambient temperature is 0~+55℃;

In some extreme temperatures, both A6 and T6 have their advantages.

To sum up, the A6 series, as our newly launched AC servo product, has many highlights. I hope this article will be helpful to your choice. If you have any other technical questions, please feel free to contact us.
