Function Display
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.

Analog set value adjustment
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.

Here the frequency is set that corresponds to the external frequency
end point bias set under A 13 .
N
Setting range 0Hz–360Hz.
The value entered here is based on the maximum voltage set value or
current set value of 10V or 20mA, respectively.

Inverter behaviour for set values < external frequency start point:
N
00: The frequency configured under A 11 is sent to the motor
01: A frequency of 0Hz 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
N
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
A frequency set value between 0.5Hz and 360Hz can be entered here (a
Y
02 must have been configured under A 01 beforehand).
Any one of the 15 multistage frequency settings from A 21 through
Y
A 35 can be assigned a frequency in the range of 0.5Hz to 360Hz.
The frequency that is sent to the motor when jogging mode is activated
Y
can be chosen from 0.5Hz to 9.99Hz.
When a stop command is issued during activated jogging mode, the
motor stops by:
00: running free
N
01: decelerating using configured deceleration time
02: decelerating using DC brake
