Timechart at SEARCH Command Input
The deceleration time for speed search operation can be set in n101.
If the setting is 0, however, an initial value of 2.0 s will be used.
The speed search starts when the Inverter’s output current is greater
than or equal to the speed search operation level (n102).
DC Injection Braking at Startup (n089, n091)
Restarts a coasting motor after stopping it. Set the DC injection braking
time at startup in n091 in units of 0.1 s. Set the DC Injection Braking
Current in n089 in units of 1% (Inverter rated current =100%). When
the setting of n091 is 0, DC injection braking is not performed and
acceleration starts from the minimum output frequency.
When n089 is set to 0, acceleration starts
from the minimum output frequency after
baseblocking for the time set in n091.
Holding Acceleration/Deceleration Temporarily
To hold acceleration or deceleration, input an ACCELERATION/
DECELERATION HOLD command. The output frequency is main-
tained when an ACCELERATION/DECELERATION HOLD command
is input during acceleration or deceleration.
When the STOP command is input while an ACCELERATION/
DECELERATION HOLD command is being input, the acceleration/
deceleration hold is released and operation ramps to a stop.
Set a Multi-function Input Selection (n050 to n056) to 16 (acceleration/
deceleration hold).
