4. RA
Sets RA speed and other variables.

RA sub-menu

Max Speed : Setting the maximum RA slewing speed.
 Acc. Rate : RA speed Acceleration / deceleration.
The lower the value, the slower the acceleration / deceleration.
Slowing the acceleration lessens the load on the mount and the motor.
Excessively high Acc. Rate requires a large current instantaneously at the
moment of acceleration, and the drive system also requires a relatively high
torque, which may cause of stall of the stepper motor.

Reverse : Specify the direction of rotation of the stepper motor.
Specify in this menu when the direction of the telescope's direction does not
match the command.
 Fast Microstep : Microstep selection for high speed mode.
TCS automatically calculates the optimum value.
Always select “Auto”.
 Slow Current (Tracking Speed Current)
Specifies the current required for low speed drive.
