Other functions
The analog signal output on terminal FM (representing frequency set
value or output current) can be adjusted using this function. However,
Y
adjustment of the pulse signal (digital frequency set value) is not
possible here. (Setting range: 0–255).
A higher start frequency results in shorter acceleration and deceleration
times (e.g. for overcoming increased static friction). When a too high
N
frequency is configured here this may result in the trip E 02 .
(Setting range: 0.5Hz–9,9Hz).
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.
N For this reasons the carrier frequency should be configured as small as
possible. Acceptable maximum settings are printed on the back of the
terminal cover. Initial value is always 5 kHz, therefore be sure, to set
correct carrier frequency when finished the procedure of initialization.
(REFER TO APPENDIX "C")
(Note: During DC braking the carrier frequency will automatically be
reduced to 1kHz).
(Setting range: 0.5kHz–16kHz).
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 .
N
- 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.
- Set the correct carrier frequency (see back of the terminal cover!).
Note: This function can not be configured while the remote operator is
being connected.
The national parameter set that will be loaded during initialization (also
refer to b 84 ) can be selected. The L100-...NFE/HFE inverter series
N
models need the parameter 01 to be configured here.

The product of the value displayed under d 01 and the factor con-
Y
figured here will be displayed using d 07 . (Setting range: 0.1–99.9).
Using this function the STOP key on the digital operator or the remote
operator can be locked.
N
00: STOP key always active
01: STOP key not active when terminals FW/RV are used
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:
N
00: 0Hz restart after FRS has been deactivated
01: Motor synchronization to the current motor speed following the
waiting time configured under b 03 .
When using a remote operator OPE-J one of the following values can
be displayed externally:
01: Current frequency
Y
04: PID actual value
06: State of digital outputs
07: Scaled actual frequency
With the exception of the STOP key, all keys of the OPE-J are inactive.
