cause a change in rotation direction. This allows rotation direction reversal using a simple
voltage source and potentiometer.
E.g. internal setpoint with rotation direction change: P402 = 5 V, P104 = 0 Hz, Potentiometer
0-10 V  Rotation direction change at 5 V in mid-range setting of the potentiometer.
At the moment of reversal (hysteresis = ± P505), the drive stands still when the minimum
frequency (P104) is less than the absolute minimum frequency (P505). A brake controlled by
the VFD is applied in the hysteresis range.
If the minimum frequency (P104) is greater than the absolute minimum frequency (P505),
the drive reverses when the minimum frequency is reached. In the hysteresis range ± P104,
the VFD supplies the minimum frequency (P104), the brake controlled by the VFD is not
applied.
