YASKAWA A1000 HHP Programming Manual page 123

Each slave drive must be assigned a unique slave address for serial communications to work. Setting H5-01 to any value
besides 0 assigns the drive its address in the network. Slave addresses do not need to be assigned in sequential order, but no
two drives may share the same address.
n
H5-02: Communication Speed Selection
Sets the MEMOBUS/Modbus communications speed.
Note: Cycle the power after changing this parameter to enable the new setting.
No.
H5-02
Setting 0: 1200 bps
Setting 1: 2400 bps
Setting 2: 4800 bps
Setting 3: 9600 bps
Setting 4: 19200 bps
Setting 5: 38400 bps
Setting 6: 57600 bps
Setting 7: 76800 bps
Setting 8: 115200 bps
n H5-03: Communication Parity Selection
Sets the parity used for communications.
Note: Cycle the power after changing this parameter to enable the new setting.
No.
H5-03
Setting 0: No parity
Setting 1: Even parity
Setting 2: Odd parity
n H5-04: Stopping Method after Communication Error
Selects the stopping method after a communications error (CE) has occurred.
No.
H5-04
Setting 0: Ramp to stop (uses the deceleration time currently enabled)
Setting 1: Coast to stop
Setting 2: Fast Stop
Setting 3: Alarm only (continue operation)
n H5-05: Communication Fault Detection Selection
Enables or disables the CE detection for communications.
No.
H5-05
Setting 0: Disabled
No communication error detection. The drive continues operation.
Setting 1: Enabled
If the drive 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 drive will operate as determined by parameter H5-04.
n H5-06: Drive Transmit Wait Time
Sets the time the drive waits after receiving data from a master until responding data.
Note: Cycle power for the setting to take effect.
