USING THE MANUAL PRESET INDEXER
SELECTING MOTION PARAMETERS
The velocity profile (motion speed and acceleration) is determined by the four
green switches; the Base Speed, Max Speed, Acceleration/Deceleration, and
Factor. Figure 5 shows a typical velocity profile of a step motor.
BASE SPEED
This is the speed at which the motor starts to run. There are 256 choices of
Base Speeds as shown in the Table 3. They range from 2 steps/second to
3,611 steps/second.
MAX SPEED
As shown in Table 2, there are 256 choices available ranging from 163
steps/second to 14792 steps/second.
ACCELERATION/DECELERATION
The step motor starts to accelerate after taking 4 steps at the base speed and
continues until it reaches the selected maximum speed taking the number of
steps set by A/D at each speed in the internally generated ramp table. A/D=0
is no acceleration (run at BASE speed only), A/D=1 is the fastest (minimum
ramp time), and A/D=F is the slowest (maximum ramp time). The step motor
starts to decelerate at the calculated point and continues until it reaches the
selected base speed and stops.
FACTOR
The F switch should be set first because it directly affects the Base and Max
speed. Table 1 lists the maximum obtainable stepping rates for all F switch
settings with the maximum speed F.
