Description

1

+5V

5V analog reference as used by

the internal DAC.

Max. load 0.5mA

2

Velocity

Used for velocity control in

stand alone operation by

supplying external 0 – 10V

signal

3

Torque

Used for max. motor current /

torque control in stand alone

operation by supplying external

0-10V signal

4

GND

Module ground (power supply

and signal ground)

5

Dir_IN

5V TTL input. Tie to GND to

inverse motor direction, leave

open or tie to 5V otherwise.

6

Tacho

This pin outputs a tacho

impulse, i.e. toggles on each

hall sensor change

7

Stop_IN

Emergency stop. Tie this pin to

GND to stop the motor (same as

the Motor Off switch on PCB).

The motor can be restarted via

the interface, or by cycling the

power supply

8

LED-Temp

5V TTL output: Toggling with

3Hz when temperature pre-

warning threshold is exceeded,

high when module shut down

due to overtemperature

9

LED-Curlim

High, when module goes into

current limiting mode

10

+5V

5V output as reference for

external purpose

11

GND

GND reference

GND reference

13

Enc_A+

Encoder A+ channel

14

Enc_A-

Encoder A- channel

15

Enc_B+

Encoder B+ channel

16

Enc_B-

Encoder B- channel

17

Enc_N+

Encoder N+ channel

18

Enc_N-

Encoder N- channel

19

CANL/USBD-

CAN low /

USB D- bus line

20

RXD/

485-

RXD signal for RS232 /

inverting signal for RS485

21

CANH/USBD+

CAN high /

USB D+ bus line

22

TXD/

485+

TXD signal for RS232 /

non inverting signal for RS485

23

USB_+VB

Use to detect availability of

attached host system (e.g. PC)

24

n.c.

25

GND

GND reference

26

GND

GND reference

Interface

Description

RS232

Short RxD and TxD for resetting the module.

USB

Use your USB interface for resetting the module

with the functions of TMCL-IDE. Please refer to the

TMCL™ Firmware Manual.
