Pin
Name
Function
1
5V_AREF
5V analog reference as used by the internal DAC. Max. load 0.5mA
2
AIN0 / VIN
Analog input: Used for velocity control in stand alone operation by
supplying external 0 - 10V signal
3
AIN1
Additional analog input. Currently unused – leave open
5
DIRIN
5V TTL input. Tie to GND to inverse motor direction, leave open or
tie to 5V otherwise.
6
GPIO1
Starting from Version 1.02: This pin outputs a tacho impulse, i.e.
toggles on each hall sensor change
7
/MOTOR_OFF
Emergency stop. Tie this pin to GND to stop the motor (same as
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, 14
+5V
5V supply as reference for external purpose
11, 12, 26
GND
GND reference
20
RXD /
RS485INV
RXD signal of module for RS232 communication (RS232 version)
Inverting RS485 signal (RS485 version)
22
TXD /
RS485NI
TXD signal of module for RS232 communication (RS232 version)
Non-inverting RS485 signal (RS485 version)
All other pins
Leave all other pins unconnected!
