13 DC injection braking command (set value = 60)
• When DC braking command is asserted while the AC drive stops, DC braking operation is
performed. When operation signal or jog operation command is asserted, the DC braking
operation is stopped and the run or jog operation is started. (Privileged operation)
14 Search command (set value = 61,62)
• To start the motor during a coast when conditioning commercial power supply to the AC drive
transfer operation is performed, the motor can be operated without tripping by using the
speed search function.
Set value = 61: Speed search starts with the maximum frequency.
Set value = 62: Speed search starts with the frequency reference value when search
command is asserted.
• Search commands with set values of 61 and 62 cannot be set at the same time.
• By inputting the run command with the search command “closed” during baseblock,
speed search starts after shutting down the AC drive output for the minimum baseblock
time (Cn-40)
• Speed search operation starts when AC drive output current is larger than the set value
of the speed search operation level (Cn-38). The frequency at which the AC drive output current
is lower is determined as the speed synchronous point: Re-acceleration/deceleration is performed
in the set accel/decel time up to the set frequency.
