3-Wire-Control Stop
(Opening button)
This control function provides an alternative to enable R/L (01,
02), in which a permanently applied level is required.
Here, only a control impulse is required to trigger the function.
The control of the FI can therefore be performed entirely with
buttons. (software version 1.5 and above)

In combination with enable R/L the output frequency can be
continuously varied. To save a current value in P113, both
inputs must be at a High voltage for 0.5s. This value then
applies as the next starting value for the same direction of
rotation (Enable R/L) otherwise start at f

Only for devices with external 24V control voltage SK 5x5E.
There is therefore also the possibility of operation with a very
low link circuit voltage. With this function the charging relay is
activated and the undervoltage and phase error detection are
deactivated.

with automatic saving
SW1.6 and above
With this motor pot. function (SW 1.6 and above) a setpoint
value (sum) is set via the digital inputs, which is
simultaneously stored. With control enabling R/L this is then
started up in the correspondingly enabled direction. On
change of direction the frequency is retained.
Simultaneous activation of the +/- function causes the
frequency setpoint value to be set to zero.
The frequency setpoint value can also be displayed or set in
the operating value display (P001=30, current setpoint MP-S’)
or in P718.
Any minimum frequency set (P104) is still effective. Other
setpoint values, e.g. analog or fixed frequencies can be added
or subtracted.
The adjustment of the frequency setpoint value is performed
with the ramps from P102/103.

If neither of the digital inputs is programmed for left or right enable, then the actuation of a fixed frequency or jog frequency will
enable the frequency inverter. The rotation field direction depends on the sign of the setpoint.

Also effective for Bus control (RS232, RS485, CANbus, CANopen, DeviceNet, Profibus, InterBus, AS-Interface)
