Remark: a: baud rate and communication agreement must be set to the same level between PC, PLC
and inverters.
b: ASCII CODE is used for S3 / H3 communication.
c: Fn_10, Fn 11 will be ineffective for inverter operation and frequency control in
communication mode.
d: frequency signal will be controlled by Fn_06, Fn_07 in communication mode.
e: PC will request data from inverter automatically to obtain information
(STATUS_LED, Vac, Vpn, Iac, Freq., RPM)
f : Inverter will double confirm the validity of new parameter when set by PC.
g : Please refer to the manual of RS-232-S3 / H3 and RS-485-S3 / H3 for detail function
and protocol.
Fn_103 - Fn_122 : Reserved
Factory setting (Fn_123)
1. All parameters will be reset to factory setting value if Fn_123 set to 1111. Some of the parameters
will be reset to specific value: Fn-05=9, Fn_06=60, Fn_37=60, and Fn39=3. The value of Fn-123
will be back to 0000 automatically after reset.
2. All parameters will be reset to factory setting value if Fn_123 set to 1110. Some of the parameters
will be reset to specific value: Fn-05=0, Fn_06=50, Fn_37=50, and Fn39=2.5. The value of
Fn-123 will be back to 0000 automatically after reset.
CPU version (Fn_124)
Fault sequence reference (Fn_125)
In order to simply troubleshooting, Inverter memorizes the last three fault codes automatically in its
EEPROM memory. Press

keys on the digital operator to refer to the faults recorded. For instance:
1. LV-C : The first fault code (the latest one) is low voltage
2. OC-d : Over current during deceleration
3. - - - - : No fault condition (only two faults occurred)
