The DIFOLD command enables (1) or disables (Ø) the drive’s current
foldback protection feature. The current foldback feature reduces the drive’s
continuous current output by 20% when sustained current has the potential
to overheat the drive. For the AR-20xE and AR-30xE drives, this feature is
always enabled.
Each drive has the specifications shown in Table 43. Note that current
ratings are for the drive, not for the motor.

Table 43 Current Foldback Ratings
If your drive is operating above its continuous rating, see Figure 42 to predict
the number of seconds until foldback occurs. For example, the graph shows
that at the drive’s peak current rating (300% of continuous), foldback occurs
after 3.375 seconds.
Note: For model AR-13xx, foldback occurs after 8.64 seconds at its peak
rating (225% of continuous).
