“3-Wire-Control Start-Right”
(Closing 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.

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)

"Motor potentiometer function
Frequency + with automatic
saving“
With this "motor potentiometer function" a setpoint value (sum) is
set via the digital inputs, and 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.
