Standby Current
In order to reduce the overall temperature of the motor, the user can specify a reduced motor current to be
applied while the motor is idle. Standby Current Percentage parameter is the percent of the user selected
maximum motor current that current should drop to after the standby period has elapsed.
Standby Current Delay is time in milliseconds after the end of all motion profiles before the current drops to the
standby level. Note that in some cases such as Cam and Gear profiles there may be no steps generated, but the
axis is still considered to be in motion if the cam or gear is still engaged. If the axis is at standby current and a new
motion profile is started, the current will automatically and immediately be restored to user selected maximum
motor current.

Drive Resolution
The default resolution of drives is 256 micro-steps per full step. With typical 200 step per revolution motor, this
results in an overall resolution of 51200 micro-steps per revolution. The user can select the number micro-steps
per full step, with the constraint that the value must be a power of 2 between 1 and 256. Any other number will
be considered invalid and result in a failed configuration request.
