Introduction of Shihlin Inverter
Introduction of Inverter
2.2 Common specification (Inverter characteristics)
Control method
SVPWM control, V/F control, facility vector control, Sensorless vector
control.
Output frequency range
0.2~1000Hz (The starting frequency setting range is 0~600Hz). Please
refer to P.187 in Chapter 4.
Resolution for
setting frequency
Digital
setting
When P.187=0, if the frequency set value is below 100Hz, the resolution
will be 0.01Hz. If the frequency set value is above 100Hz, the resolution
will be 0.1Hz. When P.187=1, the resolution of frequency will be 0.1Hz.
Analog
setting
When setting DC 0~5V signals, the resolution will be 1/500;
When setting DC 0~10V or 4~20mA signals, the resolution will be
1/1000.
Output frequency accuracy 0.01Hz
Voltage / frequency output
characteristics
Base frequency voltage
(P.19), base frequency (P.3) can be arbitrarily set
in
available range.
Constant torque model,
applicable load model
can be selected (P.14).
Start torque
150% (1Hz): When the sensorless vector control is started.
Torque boost
The torque boost setting range is 0~30% (P.0), auto boost, slip
compensation.
Acceleration/deceleration
curve characteristics
The resolution (0.01s/0.1s) of acceleration/deceleration time (P.7, P.8) is
switched by P.21
. The setting range has
0~360s or 0~3600s
for selection.
And different acceleration/deceleration curve model can be selected
by
P.29
.
DC braking
The DC braking action frequency is
0~120Hz
(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 to 0~400% (P.22).
Target frequency setting
Operation panel setting;
DC 0~5V signal setting, DC 0~10V signal setting and DC 4~20mA
signal setting, 2 voltage input or one voltage and one current input can
be selected;
Multi-speed stage levels setting; Communication setting.
PID control
Please refer to P.170~P.183 in Chapter 4.
Multi-function control
terminals
Motor starting (STF, STR), the second function (RT), the 16-speed
operation (RL, RM, RH, REX), external thermal relay (OH), reset
(RES)
, etc. (they can be set by the user with P.80~P.84, P.86)
Multi-
