B—Buffer Status
❏
Command Type: Status
❏
Valid Software Version: A
❏
Syntax: aB
❏
Units: N/A
❏
Range: N/A

Default Value: N/A

Attributes: Immediate,

Response to aB is *B or *R
Never Saved

See Also: BS
The buffer status command will report the status of the command buffer. If the command
buffer is empty or less than 95% full, the controller will respond with a *R.
The command buffer is 512 bytes long. A *B response will be issued if less than 5% of the
command buffer is free.
*R = More than 5% of the buffer is free
*B = Less than 5% of the buffer is free
This command is commonly used when a long series of commands will be loaded remotely
via RS-232C interface. If the buffer size is exceeded, the extra commands will not be
received by the controller until more than 5% of the command buffer is free.

BCDG—Buffered Configure Derivative Gain
❏
Command Type: Set-up

This buffered command is used for system tuning. This term represents the gain applied to
the derivative of the position error—in other words, the rate at which the position error is
changing. This gain produces a damping effect similar to velocity feedback.

This buffered command is used for system tuning. This term represents the gain applied to
the integral of the position error—the net accumulation of the position error over time. Thus
integral gain will contribute when a position error is not being reduced over time, as may be
caused by the effects of friction or gravity. This gain will improve overall accuracy but may
increase settling time and, if excessive, may cause a low frequency oscillation around the
commanded position.
