Figure F0-2 Accelerating and Decelerating time
Accelerating time is the time for VFD to
accelerate from zero frequency to the
maximum output frequency, as t1 showed
in figure F0-2. Decelerating time is the time
for VFD to decelerate from maximum output
frequency to zero frequency, as t2 showed in
figure F0-2.
There are 4 groups of acc./dec. time
parameters for CR600 series VFD, the other
3 groups are defined in function code
F1.13 ～ F1.18. The factory default of acc./
dec. time is determined by VFD type. For other
time groups, please choose by multi-function
terminal (refer to F7.00 ～ F7.07 function
code). Acc./Dec. time of jogging run is defined
in F1.22 and F1.23.
This function code is used to set carrier
frequency of PWM wave from VFD output.
Carrier frequency will affect the noise when
motor running, raise the carrier frequency
properly when there is demand for quiet
running. Meanwhile, raising the carrier
frequency will increase heat production and
electromagnetic interference from the VFD.
When carrier frequency exceeds factory
default value, the VFD needs to be used with
derating. Normally 5% derating of VFD current
for every 1kHz increasing of carrier frequency.

F0.21
Running direction
0 ～ 2
0
0: forward run
In this mode, the actual output phase
sequence is the same with system default.
Key and FWD terminal are both for
forward control.
1: reverse run
In this mode, the actual output phase
sequence is opposite to the system default.
Key and FWD terminal are both for
reverse control.

2: reverse run forbidden
In any condition, motor can only run
forward. This function is for situation where
reverse running can bring hazard and
property loss.
