Value Function Description Signal
09 Hold frequency During the acceleration or deceleration phase, a Low level will cause the actual
output frequency to be "held". A high level allows the ramp to proceed. Low
10 Block voltage
2
The FI output voltage is switched off; the motor runs down freely. Low
11 Quick stop
2
The FI reduces the frequency according to the programmed fast stop time from
P426. Low
12 Error acknowledgement
2
Error acknowledgement with an external signal. If this function is not
programmed, an fault can also be acknowledged by a low enable setting
(P506). 0

NOTE: Function 13 can only be used via DIN 5 up to SK 535E, sizes 1 - 4!
For SK 54xE and sizes above Size 5, there is a separate connection which
cannot be deactivated. If the motor is equipped with a thermistor, for these
devices both terminals must be bridged in order to deactivate the function
(status as delivered).

19 Setpoint 1 on/off
Analog input switch-on and switch-off 1/2 (high = ON) The low signal sets the
analog input to 0 % which does not lead to shut-down when the minimum
frequency (P104) > than the absolute minimum frequency (P505).

45 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.

47 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

. Values from other
setpoint sources (e.g. fixed frequencies) are not taken into account.
