Direction controls - This optically isolated input controls the
direction of motor rotation when all on-board direction controls
jumpers are removed. Motor rotation is CCW if the opto is driven
and CW otherwise. The direction of the motor can also be
controlled by the analog input or on-board plug on jumpers (E6,
E7, and E8).
Using on-board
Acceleration and deceleration controls -Acceleration rate is
potentiometer
non-linear resulting in an exponential velocity ramp. Constant
deceleration rate resulting in a linear velocity ramp. Accel Ramp
Pot (R14) and Decel Ramp Pot (R17) adjust the initial acceleration
and deceleration rate of the motor from 0.4 msec to 0.4 sec (accel.
single time constant) and 6.0 msec to 1.4 sec (decel. time).
Run speed and low speed controls - Run Speed Potentiometer
(R7) and Low Speed Potentiometer (R43), both independent speed
potentiometers, set the steady state run speed of the motor when
the optically isolated input RUN/STOP or LOW_SPD opto is
driven. The motor speed ramps up from the selectable MIN_SPD
threshold (enable or disable with E5 jumper) until it reaches the
final speed. Run Speed Potentiometer adjusts the final motor speed
from 8 KHz to 500 KHz and 4 KHz to 250 KHz for high and low
frequency range operation. Unlike the Low Speed Potentiometer
which is adjustable from 8 KHz to 370 KHz and 4 KHz to 180
KHz for high and low frequency ranges.
