When the feedback signal is less than the detection value set by P14.26 and its time exceeds the time set
by P14.27, then PID feedback is considered as “loss”.
When the feedback signal is greater than the detection value set by P14.28 and its time exceeds the time
set by P14.29, then PID feedback is considered as “exceeding limit”.

Fig. 6-70 Setting of communication configuration
This function is used for selecting parameters for serial communication port and setting according to LED
bits.
If the hundreds place of the function code is in MODEM mode, whenever the drive powers up, the
initialization operation will be performed once for MODEM via RS485 port on the control board, so that
the MODEM can automatically response after receiving 3 times of ringing signal of telephone line to
realize the remote control line made up from dial-up line.
Note: MV300 control board provides RS485 port only. If the communication port of the external
equipment is RS232, the RS232/RS485 conversion equipment shall be added separately.
