3-W-Ctrl.Start-Right
(Closing button)
3-Wire-Control, 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. Control of the FI
can therefore be performed entirely with buttons.
A pulse on the function "Reverse direction of rotation" (see Function 65) inverts
the present direction of rotation. This function is reset with a "Stop signal" or by
activating a button for the functions 45, 46, 49.

Motorpot.Freq.+
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 0.5 s. This value then applies as the next starting value for the same
direction of rotation (Enable R/L) otherwise start at f
MIN
. Values from other
setpoint sources (e.g. fixed frequencies) are not taken into account.

Evacuation run
above SW 1.7
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 under-
voltage and phase error
detection are deactivated.
NOTICE! There is no overload monitoring! (e.g. lifting gear)

71
Motor pot.F+ and Save ³
SW 1.6 and above
Motor potentiometer function frequency +/- with automatic saving. With this
motor potentiometer function (SW 1.6 and above) a setpoint value (sum) is set
via the digital inputs, which is simultaneously saved. 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 can also be set in the operating value display (P001=30,
'Actual. setpoint MP-S') or displayed or set in P718 and pre-set to the operating
status "Ready for switch-on".
Any minimum frequency set (P104) is still effective. Other setpoint values, e.g.
analogue or fixed frequencies can be added or subtracted.
Adjustment of the frequency setpoint value is performed with the ramps from
P102/103.

1 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.
2 Also effective for Bus control (e.g. RS232, RS485, CANbus, CANopen, …)
3 With SK 5x5 E devices the frequency inverter control unit must be supplied with power for a further 5 minutes after the last change of the motor
potentiometer in order to permanently save the data.
4 Function cannot be selected via BUS IO In Bits
