Inverter behaviour for set values < external frequency start point:
00: The frequency configured under
A 11 is sent to the motor

A value between 1 and 8 can be entered to configure the inverter’s
reaction speed to changes in analog set value at the O or OI terminal
and thus determine the amount of filtering for harmonics that may be
present with the analog signal:
1: Little filtering / fast reaction to changes in set value
8: Extensive filtering / slow reaction to changes in set value

Multistage frequency settings and jogging mode
Up to 15 multistage frequency settings can be selected using the digital inputs configured as CF1 through CF4.
Alternatively to setting the multistage frequencies under functions
A 21 through A 35 they can be set using function
F 01.
Jogging mode can be used to set up a machine manually and is activated using a digital input configured as JG.
Since the acceleration ramp is not active during jogging mode, there might be an overcurrent trip (especially when a
too high jogging frequency is chosen). Jogging mode can not be used when the jogging frequency is smaller than the
start frequency configured under
b 82 .
Multistage frequency settings have a higher priority than other frequency set values. Only the jogging frequency’s
priority is even higher.

Jogging frequency

The frequency that is sent to the motor when jogging mode is activated
can be chosen from 0.5Hz to 9.99Hz.

Jogging stop mode A 39 N
When a stop command is issued during activated jogging mode, the
motor stops by:
00: running free
01: decelerating using configured deceleration time
02: decelerating using DC brake

The external frequency set value can be individually adjusted
using functions
A 11 to A 16 . A configurable voltage or
current set value range can be assigned to a configurable
frequency range.
Furthermore, the analog input signal filtering can be adjusted
using function
A 16 .
