The direction of rotation can be defined with the preadjusted setpoint signal. In the
case of analog signals through adjustment of positive or negative voltages. In the
case of digital signals through adjustment of positive frequencies (without sign) or
negative frequencies (negative sign in the display). Following settings are possible:
In this case a direction of rotation must be adjusted via a digital input, digitally via
oP.2 or via control word SY.50 in order for the inverter to modulate. It is unimportant
which direction of rotation is adjusted, as the direction of rotation is dependent on
the setpoint.
no rotation direction set
oP.1 = 6 set direction of rot.;pos. value (also 0) -> rotation direction forward
set direction of rot.;negative value
In this case the inverter always modulates. No direction of rotation needs to be
adjusted.
oP.1 = 7 positive value (also 0)
negative value
The control word is used for the state control of the inverter via bus. In order for the
inverter to react to the control word, the respective control process must be enabled
(oP.1=8 or 9). When adjusting the direction of rotation via the control word, the
setpoint can be evaluated 0-limited (oP.1 = 8) or absolute (oP.1 = 9).
Bit Function
0 Control release 0 = control release not enabled; 1= control release
1 Reset
2 Run / Stop
3 For / Rev
4-6 Current set
7 Free
8 Fast stop
9-15 Free
If Run/Stop is to be adjusted over the control word, oP.2 must be set to
„0". The terminals F/R may not be wired (OR-operation of terminal, oP.2
and Sy.50).

enabled This bit takes effect only if di.1 Bit 0 is set.
Then the AND-operation with di.2 Bit 0 and the terminal
ST is effective); control release ST (hardware) must be
set additionally.
Triggers reset when changing from 0 => 1
0 = setpoint rotation Stop; 1 = setpoint rotation Run
(source of setpoint direction op.1 = 8 or 9)
0 = setpoint rotation forward; 1 = setpoint rotation reverse
(source of setpoint rotation op.1 = 8 or 9)
Source of set selection fr.2 = 5
0 = fast stop not activated; 1 = fast stop activated
( OR-operation with further sources for fast stop)
