Rotation [219]
Overall limitation of motor rotation direction
This function limits the overall rotation to reverse or forward
direction, or to allow both directions. This limit is prior to all
other selections, e.g. if the rotation is limited to forward
direction, a REV command will be ignored. To be able to
allow reverse and forward rotation we assume that the motor
is connected according to section , page 16.
In this menu you set the allowed rotation for the motor.
8.2.2 Remote signal Level/Edge
[21A]
In this menu you select the type of control used for the input
signals for RunFWD, RunREV and RESET that are
operated via the digital inputs on the terminal strip. The
input signals are default set for edge-control, and the input
signals will be activated by the “low to high” or in some cases
“high to low” transition of the input. When level-control is
selected, the input signals will be active as long as the input is
kept high or low (see description of selections menu [21A]
below). See also section 7.5, page 61.
Default: FWD
FWD 1
Limited to forward (right) rotation.
REV key, JOG REV key, and reverse
commands are disabled.
REV 2
Limited to reverse (left) rotation.
FWD key, JOG FWD key, and forward
commands are disabled.
See note below.
FWD+REV 3
Both rotation directions allowed.
See note below.
NOTE: When reversed rotation is selected (“REV” or
“FWD+REV” in menu [219]), this requires phase reversal
contactors. See Fig. 25, page 29.
NOTE: Jog reverse does not require any phase reversal
contactor.

FWD
NOTE: In edge control mode, at least one digital input
must be programmed to “Stop”, because the “RunFWD”
and “RunREV” commands are only able to start the
softstarter.
Default: Edge
Level 0
The inputs are activated or deactivated
by a continuous high or low signal. Is
commonly used if, for example, a PLC is
used to operate the softstarter.
Edge 1
The inputs are activated by a transition;
for Run and Reset from “low” to “high”
and for Stop from "high" to "low".
CAUTION!
Level controlled inputs DO NOT comply with
the Machine Directive if the inputs are
directly used to start and stop the machine.
NOTE: Edge controlled inputs can comply with the
Machine Directive (see Chapter 1.5.1 page 6) if the
inputs are directly used to start and stop the machine.
