8 Connecting I/O
8.1 I/O Functional Description
I/O Pin Name Type Functional Description
Frame
- Shield Connection.
Analog Input
Positive
Analog Input -10V to +10V input signal for speed or current command. The scaling of input
voltage to motor output is configured in the setup software.
Analog Input
Negative
Analog Input
-10V to +10V input signal for speed or current command. The scaling of input
voltage to motor output is configured in the setup software. For a single ended
analog signal connection, this pin should be connected to ground.
Analog Output
Analog Output -10V to +10V output signal which represents the motor speed or current. The
scaling of motor output to output voltage is configured in the setup software.
Step Digital Input The rising edge of each input pulse is accepted as one step pulse by the drive.
Direction Digital Input
When the input signal is active low, it reverses the speed or current command.
This in turn changes the direction of motor rotation.
Out 0
Digital Output Unused, do not connect.
In 0
Digital Input Unused, do not connect.
Fault
Digital Output Open collector output that pulls to ground when the drive is in a faulted state.
Ready
Digital Output Open collector output that pulls to ground when the drive is ready.
Enable
Digital Input
Input which enables the drive when an active low signal is applied and
disables the drive when a high signal is applied. The signal needs to be kept
low for the drive to remain enabled. In case of any drive interruptions or faults,
this input should be toggled from high to active low to re-enable the drive.
Brake Digital Input
Input pin which dynamically brakes the motor when it’s active low.
Limit Switch
Positive
Digital Input
Input pin which controls the positive current delivered to the motor. When the
Limit switch positive is active low, the drive stops delivering positive current to
the motor.
Limit Switch
Negative
Digital Input
Input pin which controls the negative current delivered to the motor. When the
Limit switch negative is active low, the drive stops delivering negative current
to the motor.
+5 Vout Output Internally gen5 volts for customer use. Refer to section 3.3.2.
Ground - Referenced to supply ground.
