LEDs
When powered and operated properly, the status LED will be green. When an error occurs, the LED will
change to RED and an error code will be generated in the error code register. To read and clear the error
with the software, click on the “Verify Parameters” button. To read and clear the error while in “Direct
Mode” use the “!” command. Once the error has been read and cleared, the LED will return to green and
the error code register will be cleared. Refer to the table page 20 for a list of the error codes. When the
pulse generator is running the yellow LED will be on. Refer to the dimension drawing for location of the
LEDs. For more detail on “Direct Mode” refer to the Direct Talk Mode section of user’s guide.
Baud Rates
A term used frequently in serial data communications. A “baud” is defined as the reciprocal of the shortest
pulse duration in a data word signal, including start, stop, and parity bits. This is often taken to mean the
same as “bits per second”, a term that expresses only the number of “data” bits per second. Very often,
the parity bit is included as an information or data bit. The MBC10P31 only accepts a baud rate of 115.2k.
Inputs and Outputs
Inputs:
All inputs are pulled up to 5VDC. A logic "0" activates inputs that are pulled up. An unconnected
input will always remain inactive.
Direction:
When this input is not active, the motor will be moving in the clockwise or “+” direction. When
this input is active, the motor will move in the counterclockwise or “-“ direction. This input is not read when
a software index command is given. To change direction while using the software, change the direction
option there. When two motors are used, the second motor will move in the opposite direction by default.
On/Off:
When this input is not active, the motor will be enabled or energized. When this input is active, the
motor will be disabled or de-energized.
Run:
When this input is not active, the pulse generator is stopped and will not output any pulses. When this
input is active the pulse generator will output pulses starting at the base speed rate and will ramp up and
output pulses at the max speed rate. When this input is released, the pulse generator will ramp down to
base speed and stop or hard stop depending on the deceleration option.
Max1/Max2:
This input is used to select which profile runs when the run input is activated. To use profile 1,
then this input needs to be inactive (open). To use profile 2, then this input needs to be active.
Soft Limits:
These two inputs are controlled by the direction of the pulse generator. When the pulse
generator is running in the positive direction only soft+ will work. When the pulse generator is running in the
negative direction then only soft- will work. When pulled low the motor will ramp down to base speed and
continue running until the run input is released or a hard limit is reached.
Hard Limits:
These two inputs are controlled by the direction of the pulse generator. When the pulse
generator is running in the positive direction only hard+ will work. When the pulse generator is running in
the negative direction then only hard- will work. When pulled low the pulse generator will stop all pulses to
the motor. To reverse off of a Hard Limit, change directions, and activate the run input again to move in the
opposite direction.
Busy Output:
This is an open drain output that is capable of sinking 75mA. It is current sinking when the
indexer is running and open when the indexer is not running.
Clock Output:
This is an open drain output that is capable of sinking 75mA. This output will pulse at the
same frequency as the internal clock to the motor driver. It is pulled low during the active pulse of the pulse
generator. When the pulse generator is not running this output is open.
