Introduction of Shihlin Inverter
Introduction of Inverter
3.2 Common Specification (Inverter Characteristics)
Control Method
SVPWM control, V/F control, facility vector control.
Output Frequency Range
0. 1~650Hz (The starting frequency setting range betwee 0 and 60Hz).
Digital
setting
If the frequency value is set below 100Hz, the resolution will be 0.01Hz.
If the frequency value is set above 100Hz, the resolution will be 0.1Hz.
Frequency
Resolution
Analog
setting
When setting the signal DC 0~5V, the resolution will be 1/500;
When setting the signal DC 0~10V or 4~20mA, the resolution will be
1/1000.
Digital
setting
Maximum target frequency±0.01%.

Accuracy
Analog
setting
Maximum target frequency±0.5%.
Voltage / Frequency output
Characteristics
Base voltage (
P.19
), base frequency (
P.3
) can be arbitrarily set.
Constant torque model and variable torque model can be selected (
P.14
).
Start Torque
150% 3Hz, 200% 5Hz: when using the facility vector control.
Torque Boost
The torque boost setting range between 0 and 30% (
P.0
), auto boost, slip
compensation.
Acceleration / Deceleration
Curve Characteristics
The acceleration/deceleration time (
P.7, P.8
), resolution:0.01s/0.1s,
switch by P.21. The setting range between 0.01 and 360s or 0.1~3600s
for selection. Several acceleration/deceleration curve models are
available for selection (
P.29
).
DC Braking
The DC braking action frequency range between 0 and 120Hz (
P.10
);
the DC braking time is 0~60 Seconds (
P.11
); and the DC braking voltage
is 0~30% (
P.12
). Linear braking and idling braking selection (
P.71
).
Stalling Protection
The stalling protection level can be set between 0 and 250% (
P.22
).
Target Frequency Setting
Operation panel setting, DC 0~5V signal setting, DC 0~10V signal
setting, DC 4~20mA signal setting, two voltage input or one voltage and
one current input are available for selection. Multi-speed stage level
setting, communication setting.
PID Control
Please refer to
P.170~P.183
in Chapter 5.
Multifunction Control
Terminals
Motor starting (STF, STR), the second function (RT), ‘16-speed
operation’(RL, RM, RH, REX), external thermal relay (OH), reset
(RES), etc. (can be set by the user (
