Transistorized inverter.

Note: 1. When more accurate control is required for your application, set the other parameters as
2. Because of the learning system, this control is not valid at the first time in the optimum
acceleration/deceleration mode. Also, this mode is only valid for frequency setting of 30.01Hz or
3. When the advanced magnetic flux vector control has been selected using Pr. 80 and Pr. 81, the
settings of the energy-saving mode and elevator mode are ignored. (Advanced magnetic flux
vector control has higher priority.)
4. If an overvoltage (OV3) trip has occurred during operation in the optimum acceleration/
deceleration mode (setting "3"), re-set Pr. 8 "deceleration time" to a larger value and restart
operation in this mode.
5. When the "energy-saving mode" (setting "4") is used to decelerate the motor to a stop, the
deceleration time may be longer than the preset value. Also, overvoltage is more likely to occur in
this mode as compared to the constant-torque load characteristics, therefore set the deceleration
time to a larger value.
