AKD PDMM User Guide | 7.4.4 Motor Peak Current Time
7.5 Arms. This configuration effectively increases the time that foldback will be applied to the drive before
faulting.
7.4.4 Motor Peak Current Time
Peak current (MOTOR.IPEAK) along with coil thermal constant (MOTOR.CTFO) are used to determine
the maximum time the motor can sustain peak current. The maximum time (IL.MFOLDD) is displayed in
the
Foldback
screen as shown below:
7.4.5 Motor Foldback Ramp
Once the maximum time for motor peak current has elapsed, if the move profile still demands peak current
from AKD PDMM, the drive will exponentially lower the current applied to the motor. The Time Constant
(IL.MFOLDT) dictates the profile. A smaller time constant represents a steeper decline in current applied
to the motor.
