■ In case of replacing inverter of software version V116 or earlier
Regarding all of the parameters on Table 1, copy all of the parameter setting values from V116 or earlier version inverter, and then set
them to V120 or later version inverter. Same motor control characteristics will be obtained.
f456 to f458 are manufacturer setting parameters. However, change these parameters according to Table 4 for achieving
same motor control characteristics.
(f456 and f457 do not exist on V110 or earlier version inverter.)
■ Impact of using traditional IE1 motor with default setting
When traditional IE1 motor is driven by V120 or later version inverter with their default setting values described on Table 3,
following operation can be impacted.
- Torque boost is set to low. Therefore, motor torque can be insufficient at low speed.
Countermeasure: Set the parameter on Table 4.
- Motor rated speed is set to high. Therefore, motor slip can become larger than expected one at vector control.
Countermeasure: Set the parameter values on Table 4, and apply auto tuning.
■ Search changed parameters（ （ （ （ g g g g r r r r u u u u ） ） ） ）
In case of copying parameters from V116 or earlier version inverter to V120 or later version inverter, the parameters described on
Table 1 are searched on the Searching Changed Parameters (gru: Automatic edit function).
Copying on opposite direction is led to the similar result.
(f456 and f457 do not exist on V110 or earlier version inverter.)
■ Communication tool（ （ （ （ PCM002Z） ） ） ）
In case of reading the parameters of V116 or earlier version inverter by the parameter list of V120 or later version (for IE3 motor) in
maintenance communication tool (PCM002Z), PCM002Z displays as 'modified' for the parameters described on Table 1.
Reading with the opposite relation of their software version is led to the similar result.
(f456 and f457 do not exist on V110 or earlier version inverter.)
