Special Instruction
1. Host computer cannot restore to factory setting. It can read but not write these parameters: F08
(Asyn motor parameter) and F17 (SCI parameter).
2. Host computer cannot modify F01.00 (user password). But it can write F01.00 to verify user
password. When verified, host computer access modifying function parameter of inverter. After
modifying, write invalid password into F01.00 to disable this access.
3. If many multi-function input terminals setting are the same, it may cause dysfunction. Therefore, the
user should avoid this case when modify the multi-function terminal function via the MODBUS.
