Function: STN (factory default) Function: STN (factory default) Affected parameters: C0 - C7 Affected parameters: C0 - C7
If the frequency inverter should be set back to its factory default setting, the following procedure must be done:
1.) Programm one of the inputs 1-8 with the parameters C0 - C7 to STN (setting: 07).
2.) Interconnect the programmed input with P24 (either with a switch or with a wire bridge).
3.) Switch off the power supply.
4.) Wait until the charge control goes out and switch on the power supply afterwards.
5.) Wait for app. 6 s after switching on the power supply and then open the interconnection between STN and P24.
Remarks: Remarks:
Instead of mains OFF/ON it is possible to release a reset to do the factory default setting.
Therefore a second input must be programmed to the function RS (setting: 18).
In both cases (mains OFF/ON or reset) you have to wait for at least 6 s. Elsewhere the inverter will not be initialised cor-
rectly.
If the software lock function is activated it is not possible to release a factory default setting.
Function: SET (2nd set of parameters) Function: SET (2nd set of parameters) Affected parameter: C0 - C7, A0 - A3, A23, A24, A62, Affected parameter: C0 - C7, A0 - A3, A23, A24, A62,
A63, A98, F2, F6 - F8 A63, A98, F2, F6 - F8
With this function it is possible to program a 2nd independent set of parameters which includes the following:
F2 frequency reference value A0 control method
F6 1st acceleration time A1 Motor nominal power
F7 1st deceleration time A2 Number of motor poles
F8 voltage boost A3 ASR constant
A23 Electronic motor protection
A24 Motor protection characteristik
A62 Motor voltage frequency
A63 Maximum frequency
A98 Motor data selection
Programming the 2nd value
1.) Programm one of the inputs 1-8 to the function SET (setting: 08).
2.) Interconnect the programmed input with P24.
3.) Select one of the above listed parameters. It will show its factory default value.
4.) Adjust a new (second) value and store it by pressing the FUNC key.
5.) Repeat the steps 3 and 4 for all other parameters you want to adjust.
Procedure
By interconnecting the programmed input with P24 the 2nd set of parameters can be activated, opening the interconnec-
tion the 1st set is activated.
Remark Remark
The frequency inverter has the possibility of a 2nd set of ramps (CH1) independent of the 2nd set of parameters (SET). In
other words, the unit has 3 acceleration times and 3 deceleration times!!
If you change from the 1st to the 2nd set of parameters before the new value is stored by pressing the FUNC key, it might
be possible that the new value is stored for both 1st and 2nd set. Therefore never change the set of parameters if you
adjust a value!!
Switching from one to another step can be only performed during STOP (pulse inhibit).
Switch the SET input before the start command (FW or REV). If both contacts are closed simultaneously, it might be possi-
ble that the 2nd set of parameters cannot be activated.
