C41 Local /Remote control select description
(Selected by pressing Reset & Enter keys Simultaneously).
Every time these two keys are pressed the control mode toggles
From one to the other. This is a useful function for commissioning (quick, mode change over).
For example if the Start/stop and Frequency setting is set to communication method.
(F04=2 & F05=4), then the inverter can be put to local mode by this method.
This function is useful for quick change over between local and remote modes
For setting frequency and run functions of the inverter, in local mode there is no need to change the
setting of parameters F04 & F05.
In local mode.
Run/stop and frequency can be set from the keypad.
Set C41=000 for frequency to be set by up/down keys.
Set C41=001 for frequency to be set by VR (Potentiometer) on keypad.
F04&F05 setting are ineffective.
In Remote mode.
Run/stop & frequency functions will be according to the setting of parameters
F04 (run modes) & F05 (Frequency modes).
Refer to F11~F14
1.)
If the C44 scan time is set to 80 ms as an example (i.e N=10) then digital input signals on for less
than 80 msec will be ignored.
2.)
If the scan signal is seen for N times (scan times), the inverter takes it as signal change. If it is seen
for less than N times, it is seed as noise. One scan time: 8ms.
3.) User can set scan interval time according to noise in the operation environment. Extend C44/C45 if
noise is a problem, however this will reduce the scan response time.
