Product Features
● Automatic restart after instantaneous power failure function with frequency search
Detection of coasting speed (frequency search function) prevents the motor speed from decreasing at a restart, starting the motor smoothly with less output current.
● Power-failure deceleration stop function/operation continuation at instantaneous power failure function
The motor can be decelerated to a stop when a power failure or undervoltage occurs to prevent the motor from coasting.
This function is useful to stop a motor at power failure as a fail safe of machine tool, etc.
With the new operation continuation function at instantaneous power failure, the motor continues running without coasting even if an instantaneous power failure occurs during *1
● Brake sequence mode ...... is useful for mechanical brake control of a lift.
● Regeneration avoidance function ...... prevents regenerative overvoltage in a pressing machine.
● Optimum excitation control ...... can save more energy with the maximum motor efficiency control.
● Main circuit power supply DC input ...... can be connected to DC power supply.
● Enhanced I/O terminal function ...... supports switchover of analog input (voltage / current).
● Password function ...... is effective for parameter setting protection.
and so on
- *1 : The inverter may trip and the motor may coast depending on the load condition.
Energy saving for fans and pumps
● Load pattern selection (Pr. 14)
Optimal output characteristics (V/F characteristics) for application or load characteristics can be selected.
● Optimum excitation control (Pr. 60)
With Optimum excitation control to achieve the highest motor efficiency, further energy saving can be achieved.
