Run/Stop/Pulse |
I |
Run/Stop signal for 0-5V analogue, Lo/Hi Speed and External POT mode. In Pulse/Direction mode, it accepts pulse input. |
|
3 |
Direction / +Limit |
I |
Direction input for 0-5V analogue, Lo/Hi Speed and Pulse/Direction mode. It is the +limit switch input in External POT mode. When +Limit is activated, the motor speed decelerates to zero in the acceleration set by Ramp potentiometer. The +Limit is only activated when the voltage applied to 0-5V input is 2.5-5V. |
|
4 |
Speed / (-)Limit |
I |
Speed selection input in Lo/Hi speed mode. It is the -limit switch input in External POT and 0-5V Speed mode. When +Limit is activated, the motor speed decelerates to zero in the acceleration set by Ramp potentiometer. In External POT mode, the –Limit is activated only when the voltage applied to 0-5V input is 0-2.5V. In 0-5V speed mode, the –Limit is activated only when Direction input is connected to Signal GND. |
|
5 |
Enable / Disable |
I |
This signal is used to enable or disable the power stage. Usually left it unconnected to enable the power stage. |

Signal GND |
GND |
Signal ground. It is common with the power ground. |
