If JP7 is installed, set the maximum rate potentiometer (R28)
to full CW (clockwise) position and use the maximum speed
potentiometer (R38) to set desired maximum speed. To
cause the pulse generator (PG) to output pulses, the
RUN/STOP terminal is tied to 0Vdc. At that time the PG
will send pulses out of the clock output terminal and if
ramping is selected, will start to ramp up to the maximum
speed. Disconnecting the RUN/STOP from 0Vdc causes the
PG to decelerate to minimum speed and stop. If JP6 is
selected for no downslope, when the RUN/STOP line is
disconnected the unit will stop outputting pulses immediately
and the motor will stop as fast as possible (load and speed
dependent). Ramping is used to significantly increase the
operating speed of a step motor, especially when driving
large inertial loads, without stalling the motor. The motor
starts running at a speed below the start/stop limit (base
speed),accelerated (ramped) at a rate that avoids stalling,
thereby reaching speeds ten times the base speed or more. At
the end of a run the motor is decelerated (ramped) to the
base speed for accurate stopping.
