09-05 COM2 Transmission Speed (Keypad) Unit: 0.1
Control
mode
VF VFPG SVC FOCPG TQRPG
Factory Setting: 9.6
Settings 4.8 to 115.2kbps
 This parameter is used to set the transmission speed between the RS485 master (PLC, PC,
etc.) and AC motor drive.
09-06 COM2 Transmission Fault Treatment (Keypad)
Control
mode
VF VFPG SVC FOCPG TQRPG
Factory Setting: 3
Settings 0 Warn and keep operating
1 Warn and RAMP to stop
2 Warn and COAST to stop
3 No warning and keep operating
 This parameter is set to how to react if transmission errors occur.
09-07 COM2 Time-out Detection (Keypad) Unit: 0.1
Control
mode
VF VFPG SVC FOCPG TQRPG
Factory Setting: 0.0
Settings 0.0 ~ 100.0 sec
 If Pr.09-03 is not equal to 0.0, Pr.09-02=0~2, and there is no communication on the bus during
the Time Out detection period (set by Pr.09-03), “cE10” will be shown on the keypad.
09-08 COM2 Communication Protocol (Keypad)
Control
mode
VF VFPG SVC FOCPG TQRPG
Factory Setting: 13
Settings 0 Modbus ASCII mode, protocol <7,N,1>
1 Modbus ASCII mode, protocol <7,N,2>
