Mode 4
Digital frequency reference value (1), one
operating direction (FWD).
The frequency reference value can be set as a fixed
frequency (FF1 = 20 Hz) or as a digital reference
value. This digital frequency reference value can
be increased with the UP control command and
lowered with the DOWN control command. If UP
and DOWN are activated at the same time, DOWN
will register.
Mode 5
digital frequency reference value (2)
One operating direction (FWD); digital frequency
reference value set with the UP (increase) and
DOWN (lower) control commands. If UP and
DOWN are activated at the same time, the
frequency reference value will be set to zero. An
external fault message (EXTFLT) can be connected
to input DI3 (see mode 1).
Mode 6
digital frequency reference value (3)
Two operating directions (FWD, REV); digital
frequency reference value set with the UP
(increase) and DOWN (lower) control commands
If UP and DOWN are activated at the same time,
DOWN will register.
Mode 7
Fixed frequencies (2)
One operating direction (FWD); fixed frequency
reference value via binary-coded inputs:
An external fault message (EXT FLT) can be
connected to input DI3.
Mode 8
Machine control (1)
ENA enable signal
The operating direction will be determined based
on the DIR (Low = FWD / High = REV) control
command. The frequency reference value is set via
the potentiometer (0 - +10 V) or via the fixed
frequency (FF1 = 20 Hz).
Note:
If there is a wire breakage at DI2 (DIR = REV), the
operating direction will be reversed automatically
(FWD)!
