At the moment of reversal (hysteresis =

P505), the drive stands still when the minimum
frequency (P104) is smaller than the absolute minimum frequency (P505). A brake which
is controlled by the FI has not been 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 FI supplies the minimum frequency (P104), the brake controlled by the FI is not
applied.
NOTE: The function -10V – 10V is a description of the method of function and not a
reference to a bipolar signal (see example above).
4 = 0 – 10V with error 1, “0 – 10 V with switch-off on error 1“: If the 0% adjustment value in
(P402) is undershot, the error message 12.8 "Analog In Min. undershot" is activated.
Overshooting of the 100% adjustment value in (P403) activates the error message 12.9
"Analog In Max. overshot".
Even if the analog value is within the limits defined in (P402) and (P403), the setpoint
value is limited to 0 - 100%.
The monitoring function only becomes active if there is an enable signal and the analog
value has reached the valid range (≥(P402) or ≤(P403)) for the first time (E.g. Build-up of
pressure after switching on a pump).
5 = 0 – 10V with error 2, “0 – 10 V with switch-off on error 2“:
See setting 4 ("0 – 10 V with error switch off 1“), however:
In this setting the monitoring function only becomes active if an enable signal is present
and the time during which the error monitoring is suppressed has elapsed. This
suppression time is set in parameter (P216).
