■
H5-05: Communication Fault Detection Selection
Enables or disables the CE detection for communications.
Setting 0: Disabled
No communication error detection. The regenerative unit continues operation.
Setting 1: Enabled
If the regenerative unit does not receive data from the master for longer than the time set to H5-09, then a CE fault will be
triggered and the regenerative unit will operate as determined by parameter H5-04.
■
H5-06: Drive Transmit Wait Time
Sets the time the regenerative unit waits after receiving data from a master until responding data.

■
H5-07: RTS Control Selection
Enables or disables RTS control.
Setting 0: Disabled. RTS is always on.
Use this setting with point-to-point or multi-drop RS-422 communications.
Setting 1: Enabled. RTS switches while sending.
Use this setting when using RS-485 signals for communications or when using the RS-422 signals for point-to-point
communications.
■
H5-09: Communications Fault Detection Time
Sets the time the communications must be lost before the regenerative unit triggers a CE fault.
■
H5-11: Communications Enter Function Selection
Selects whether an Enter command is necessary to change parameter values via MEMOBUS/Modbus communications.
Refer to
.
Setting 0: Enter command necessary
Parameter changes become effective after an Enter command. An Enter command must only be sent after the last
parameter change, not for each single parameter.
Setting 1: Enter command not necessary
Parameter value changes become effective immediately without the need to send an Enter command.
