However as the motor is geared motor, the ratio of the gear box determines the rotation of the output shaft of the
motor for each rotation of the base motor.
output shaft(rpm) = base motor(rpm) / gear ratio
counts per rotation = counts per rotation X gear ratio
for output shaft of base motor
For example, A motor of 200 RPM with base motor of 18000 rpm, the gear ratio is 90. Hence for a full rotation of the
output shaft in this motor, the number of counts to be programmed would be 1336 x 90 = 120,240 steps.
This means output shaft will complete one rotation when Hex value of 120240 counts is set to register 16 and 18,
LSB and MSB respectively.
Position Control in Software
When drive is connected and put in Position Control mode, software will look like this.
In Position control mode there are two ways to control position:
Absolute Position control
and
Relative Position
control
.
ABSOLUTE POSITION
In this control mode motor will move precisely until entered count is not obtained. Position command can be given by
putting number in Absolute Position textbox and clicking 'Go to absolute position' button. The direction is
automatically managed by the drive. For example writing 4000 and clicking button moves the motor forward to 4000
