6. 03- 00~03- 05=【11】Disable Acc/Dec function
When an input terminal is set to function【11】and is turned on, acceleration and deceleration function will
be disabled and the frequency at the time is maintained. ( constant speed mode)
If the input is turned off , acceleration and deceleration function is enabled again.
For an example see the following diagram.

7. 03- 00~03- 05=【12】Main/ / Alternative Run Source Select
When an input terminal is set to function【12】and is turned on, the run command source is according to
parameter 00-03(Alternative Run source).If the Input is off it will be according to 00-02 ( Main run source).
8. 03- 00~03- 05=【13】Main/ Alternative Frequency Source Select
When an input terminal is set to function【13】and is turned on, the frequency source is according to
parameter 00-06(Alternative Frequency source).If the Input is off it will be according to 00-05 ( Main
Frequency Source).
9. 03- 00~03- 05=【14】Rapid Stop (controlled deceleration stop)
When an input terminal is set to function【14】and is turned on , inverter decelerates to stop according to
deceleration time 2.
10. 03- 00~03- 05=【15】Base Block (Coast to stop)
When an input terminal is set to function【15】and is turned on, inverter output is turned off.
