Pin Label Direction Description
3 IN1/ENC_A Input General purpose digital input
Incremental encoder input channel A
+24V tolerant, programmable pull-up (for IN1/IN2 together) to +5V
3 IN2/ENC_B Input General purpose digital input
Incremental encoder input channel B
+24V tolerant, programmable pull-up (for IN1/IN2 together) to +5V
5 STOP_L/STEP Input STOP left switch input
STEP pulse input
input optically isolated, +24V compatible
6 STOP_R/DIR Input STOP right switch input
DIR input
input optically isolated, +24V compatible
7 ISO_COM Power Common positive (+24V_ISO) or negative (GND_ISO) isolated
supply input for optically isolated inputs
8 OUT0 Output (OD) Open-Drain output. Output will be pulled low when activated.
Voltages up-to logic supply input level (or main supply input in
case separate logic supply is not used) are supported here. Max.
continuous pull-down current: 100mA
Table 9: I/O Connector Pin Assignment
All pins marked light green offer functional isolation towards main supply input. In case this is not required
ISO_COM may be connected to main ground or supply input, of course. The opto-couppler used are AC
types. This way, either high side switches or low side switches for both inputs are supported.
5 On-Board LEDs
The board offers two LEDs in order to indicate board status. The function of both LEDs is dependent on the
firmware version. With standard TMCL firmware the green LED should be flashing slowly during operation
and the red LED should be off. When there is no valid firmware programmed into the board or during
firmware update the red and green LEDs are permanently switched on. During reset to factory default
values the green LED will be flashing fast. With CANopen firmware both LEDs are switched on/off/flashing
according to standard defintion.
