PTO Accel / Decel Pulses (ADP) (ADI=0) or File:Elem (ADI=1)
The PTO ADP (Accel/Decel Pulses) defines how many of the total pulses
(TOP variable) will be applied to each of the ACCEL and DECEL
components. The ADP will determine the acceleration and deceleration
rate from 0 to the PTO Output Frequency (OF). The PTO Output
Frequency (OF) defines the operating frequency in pulses/second during
the run portion of the profile.
In the example below (when ADI=0),
• TOP (total output pulses) = 12,000
• ADP (accelerate/decelerate pulses)= 6,000 (This is the maximum
ADP value that may be entered without causing a fault. The run
portion will equal 0.)

TIP
When entering the ADP parameters, the PTO will
generate an Accel/Decel Error if one of the following
conditions occur:
• The PTO ADP for accel and/or decel is negative.
• The total pulses for the acceleration and deceleration
phases is greater than the total output pulses to be
generated (TOP).
Acceleration and deceleration values can either be
identical (ADI = 0), or a unique value for each (ADI = 1).
