Stopping Methods
This section explains methods of stopping the Inverter.
‹
Selecting the Stopping Method when a Stop Command is Sent
There are two methods of stopping the Inverter when a Stop Command is sent:
•
Deceleration to stop
•
Coast to stop
Set constant b1-03 to select the Inverter stopping method.

b1-05
Operation selection for
setting E1-09 or less Used to set the method of
operation when the frequency
reference input is less than the
minimum output frequency
(E1-09).
0: Run at frequency reference
(E1-09 not effective).
1: STOP (Frequencies below
E1-09 in the coast to stop
state.)
2: Run at min. frequency.
(E1-09)
3: Run at zero-speed (Frequen-
cies below E1-09 are zero)

Zero-Speed Oper
b2-01
Zero-speed level (DC
injection braking
starting frequency) Used to set the frequency
which starts DC injection brak-
ing in 1% units when decelera-
tion to stop is selected.
When b2-01 is less than E1-09,
E1-09 becomes the DC injec-
tion braking starting frequency.
