Frequency Inverter ST600 Series High-Performance Multifunction VFD Function parameter list
-139-
invalid.
The larger the DC brake current, the stronger the brake
force. The DC brake current before startup refers to the
percentage relative to rated VFD output current.
Setting range of P01.03: 0.0–100.0%
Setting range of P01.04: 0.00–50.00s
Acceleration/dec
eleration mode
This function code is used to select the frequency variation
mode during starting and running.
0: Straight line; the output frequency increases or
decreases in straight line;
fmax
Output frequency f
t1 t2
Time t
1: S curve; the output frequency increases or decreases in
S curve;
S curve is generally used in cases where smooth start/stop
is required, eg, elevator, conveyer belt, etc.
Output frequency f
Time t
fmax
t1 t2
Note: When set to 1, it is required to set P01.06, P01.07,
P01.27 and P01.28 accordingly.
Time of starting

acceleration S
curve
The curvature of S curve is determined by acceleration
range and acceleration and deceleration time.

t1=P01.06
t2=P01.07
t3=P01.27
t4=P01.28

curve
0: Decelerate to stop; after stop command is valid, the VFD
lowers output frequency based on the deceleration mode
and the defined deceleration time, after the frequency drops
