ACCELERATION
Default: 1000
Range: 0 to 65535
This parameter defines the acceleration ramp rate used by the axis for a move. It has four
meanings depending on the Acceleration and Deceleration Mode bits in the MODE
word.
In Mode 0, this parameter is interpreted as acceleration rate and is expressed in Position
Units/sec/sec. If SCALE is set so one Position Unit equaled 0.001", then a value of 200
would represent an acceleration rate of 0.200 inches/sec/sec. In Mode 0, the relationship
between the ramp distance, ACCELERATION and SPEED is:
Ramp Distance = SPEED x SPEED
ACCELERATION x 2
ACCELERATION = SPEED x SPEED
Ramp Distance x 2
In Mode 1, this field is an acceleration rate and is expressed in 1000 position
units/sec/sec. If the SCALE is set so one position unit equal 0.001”, then a value of 200
would represent an acceleration rate of 200 inches/second/second. In Mode 1, the
relationship between the ramp distance, acceleration and speed is:
Ramp Distance = SPEED x SPEED
ACCELERATION x 2000
ACCELERATION = SPEED x SPEED
Ramp Distance x 2000
In Mode 1, if one Position Unit equals 0.001", an ACCELERATION of 200 would
represent an acceleration rate of 200 inches/sec/sec.
In Mode 2, this parameter defines the distance in position units to the specified
SPEED .
In Mode 3, it defines the time in milliseconds to the specified SPEED .
