HD2 Series Inverter Function Parameter List
-140-
DC brake current
before start
During starting, the inverter will first perform DC
brake based on the set DC brake current before
startup, and then it will accelerate after the set DC
brake time before startup elapses. If the set DC
brake time is 0, DC brake will be 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 inverter
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, such as elevator, conveyer
belt, and so on.

Note: When set to 1, it is required to set P01.06,
P01.07, P01.27 and P01.28 accordingly.

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