LED Indicators 4.4
Controller Features 4-7
In the Mode word of the geared axis, Gearing mode is selected with axis 0 as the master and will
use Acceleration/Deceleration Mode 1. The Gear Type bit is cleared indicating that the axis will
gear to the master's Target Position. It will move at half the speed of the master because the gear
ratio is 5000 divided by 10,000. Assuming that the gear ratio is 0 when the slave is issued this
command, it will take 100 milliseconds to ramp the gear ratio from 0/10,000 to 5000/10,000 at
50/10,000 per millisecond.

In this example, the master is given the exact command as the previous example.
The slave axis's Mode word is the same, except that Acceleration/Deceleration Mode 2 is used,
which ramps the axis based on the master's distance. The final ratio is 1:1 (10,000/10,000). The
ramp up to this ratio will occur while the master moves from 1000 to 2000 position units (as given
by the starting position in the Deceleration field, the master move length given in the Acceleration
field, and the master move direction given by the sign on the Speed field).
As the master moves the 1000 position units, the slave will move 500 position units since its
average speed is one half of the master speed while ramping. This means that if the master is at
a position of 1000 and moving toward 2000 and the slave is at a position of 1500 when the slave
receives the command, both axes will reach 2000 at the same time. This is useful for flying cutoff
saw applications.
4.4 LED Indicators
Understanding the CPU LED Indicators
The CPU module, labeled RMC100, has five LEDs. Each is labeled as follows:
CPU
Status
This LED can be in the following states:
Red
On power up, this LED will be red until the firmware is
started.
Solid
Green
This indicates that the module is running correctly.
Flashing
Green
This indicates that the Flash is being written to or
erased. Do not power down the RMC while the LED is
