b 81
Y
The analog signal output on terminal FM (representing frequency
set value or output current) can be adjusted using this function.
However, adjustment of the pulse signal (digital frequency set
value) is not possible here. (Setting range: 0–255).
80
Start frequency
adjustment
b 82
N
A higher start frequency results in shorter acceleration and
deceleration times (e.g. for overcoming increased static friction).
When a too high frequency is configured here this may result in
the trip
E 02
. (Setting range: 0.5Hz–9,9Hz).
0.5
Carrier frequency
b 83
N
High carrier frequencies result in less motor noise and less motor
power dissipation but on the other hand cause higher dissipation
within the power amplifier and more noise in the motor and mains
supply cables. For this reasons the carrier frequency should be
configured as small as possible. (Note: During DC braking the
carrier frequency will automatically be reduced to 1kHz).
(Setting range: 0.5kHz–16kHz).

Initializing mode
b 84
N
Two different methods for initializing the inverter can be chosen
from:
00: Clearing the trip history register
01: Reinstalling the factory standard settings
For clearing the trip history register or reinstalling the factory
standard settings do the following:
- Make sure that the parameter 01 has been entered under
function
b 85
(European version).
- Enter 00 or 01 under
b 84
.
- On the digital operator, press the two arrow keys and the
FUNC key simultaneously.
- While holding down the keys mentioned above press the
STOP key shortly and wait about 3 seconds for the LED
display to show the message
d 00
in a blinking manner.
- Now release the keys again. The initialization has now been
completed.
Note: This function can not be configured while the remote
operator is being connected.

National version
b 85
N
The national parameter set that will be loaded during initialization
(also refer to
b 84
) can be selected. The L2000-...NFE/HFE
inverter series models need the parameter 01 to be configured
here.

The product of the value displayed under
d 01
and the factor
configured here will be displayed using
d 07
. (Setting range: 0.1–
99.9).

STOP key
locking
b 87
N
Using this function the STOP key on the digital operator or the
remote operator can be locked.
00: STOP key always active
01: STOP key not active when terminals FW/RV are used
00
Operation method
when FRS signal is
cancelled
b 88
N
Activating a digital input configured as FRS causes the inverter to
be shutdown and the motor to run free. Two methods are
available for deactivating the FRS input:
00: 0Hz restart after FRS has been deactivated
01: Motor synchronization to the current motor speed following
the waiting time configured under
b 03
.

Remote display

b 89
Y
When using a remote operator OPE-J one of the following values
can be displayed externally:
01: Current frequency 02: Motor current 03: Running direction
04: PID actual value
05: State of digital inputs
06: State of digital outputs
07: Scaled actual frequency
With the exception of the STOP key, all keys of the OPE-J are
inactive.
