Oriental motor BLH Series - Setting of RS-485 Communication

81
Modbus RTU control (RS-485 communication)
11.5 Setting of RS-485 communication
Set parameters required for RS-485 communication before performing communication. Use the
MEXE02
to set
parameters.
11.5.1 Parameters updated when turning on the power
These are parameters related to sending and receiving via RS-485 communication.
•
They are out of the range of Conguration.
•
They are not initialized even if "Batch data initialization" of the maintenance command is executed.
•
They are initialized if "All data batch initialization" of th maintenance command is executed.
Turning on the power again after "All data batch initialization" was executed may change the communication setting,
thereby causing communication to disable.
•
They are initialized if "Restored to the factory setting" of the
MEXE02
is executed.
Parameter name Description Initial value
Communication ID Sets the address number (slave address). −1: The switch setting is of the driver followed
Baudrate Sets the transmission rate. 4: 115,200 bps
Communication order Sets the byte order of 32-bit data. 0: Even Address-High Word & Big-Endian
Communication parity
Sets the communication parity for RS-485
communication.
1: Even parity
Communication stop bit
Sets the communication stop bit for RS-485
communication.
0: 1 bit
Transmission waiting time
Sets the transmission waiting time for RS-485
communication.
3.0 ms
Silent interval This is a parameter to set the silent interval. 0.0: Set automatically
11.5.2 Parameters updated immediately after rewriting
These are parameters related to communication alarms, information, and error detection.
They are updated immediately after the parameter is rewritten.
Parameter name Description Initial value
RS-485 communication timeout alarm
Sets the condition in which the
RS-485 communication timeout alarm is generated.
0: Not monitored
RS-485 communication error alarm
Sets the condition in which the RS-485 communication
error alarm is generated.
3
RS-485 communication error information
Sets the condition in which the RS-485 communication
error information is generated.
3
Slave error response mode Sets the response when the slave error occurred. 1: Exception response is returned
