(2) Acceleration constants (Tace) (Cn-08 )
Sets the acceleration time during which the inverter output frequency reaches
from 0% to 100% .
(3) Deceleration constants (Tdec) (Cn=09)
Sets the deceleration time during which the inverter output frequency changes
from 100% to 0% .
(4) DC injection braking voltage (DBVOL) (Cn-10)
Sets the DC voltage that the inverter outputs at DC injection braking time in units
of 0 .1 V .
(5)
DC injection braking time at stopping (DBTIM) (Cn-11)
Sets the braking time in units of 0 .1 second during which DC injection braking is
applied at stopping . When the DC injection braking time is 0, the operation stops
after coasting, with the minimum output frequency (constant 6) .
(6)
DC injection time at starting (DBTWM) (Cn-12)
Sers the braking time in units of 0 .1 second during which DC injection braking is
applied at starting (by inputting a forward run command or reverse run command) .
When the DC injection braking time is 0, acceleration begins with the minimum out-
put frequency .
(7) Frequency command gain (FGAIN) (Cn-13)
Sets the main-speed frequency command gain in units of 0 .01 . (See Fig . 17) .
(8) Frequency command bias (FBIAS) (Cn-14)
Sets the main-speed frequency command bias in units of 0 .1%, (See Fig . 17) .
(9) Frequency command upper limit (FOUL) (Cn-15)
Sets the upper limit of the frequency command in ratio to the maximum fre-
quency in units of 1%, (See Fig . 17) .
(10) Frequency command lower limit (FOLL) (Cn-16 )
Sets the lower limit of the frequency command in ratio to the maximum fre-
quency in units of 1% . (See Fig . 17) .
(11) Troublesome frequencies can be blocked by setting in Cn-17 to Cn-19 in
units of 0 .1 Hz .
All frequencies t 1 Hz of the blocked setting are not available
for frequency commands .
