Maximum output frequency of the drive
Upper limit frequency of the drive
Rated frequency of the motor
Output frequency when a 10 V voltage
command is input
Output frequency when a 10 V voltage

Operation restarts according to the
motor speed automatically if F-CC is
ON when the power is recovered from
instantaneous power failure.
In case of an instantaneous power
failure, the motor speed is reduced
automatically to continue operation.
Control is performed so that the output
voltage does not lower when the
source voltage drops.
An S pattern is used to accelerate and
decelerate the motor speed.
Do not set the maximum frequency above 80 Hz if the motor is a general-
purpose motor not designed for high-speed operation.
