Function codes 16, 17, 18
In order to avoid machine resonances during acceleration and
deceleratlon, due to the output freguency, 3 trequency notches
ot 1 Hz each can be programxned in. The parameter variables are
in Hz.

Furiction code 19
The control mode and the motor voltage control can be set uslng
fu.nction code 19, vla keyboard or terminals. (Factory setting 00).
- Data code 00
The tunctions are controlled via the terminal block connectians;
the „P.UN“ and „Stop“ keys an the keyboard are not ettective.
The motor voltage depends on the rotational tield frequency as
set via function codes 09 and 10.
- Data code 01
The furictions are also controlled via the terminal block
connections; the „RUN“ and „Stap“ keys are not etfective.
The motor voltage is set depending on the rotational
field trequency and the necessary torque.
