Introduction of Shihlin Inverter
Introduction of Inverter
2.2 Common specification (Inverter characteristics)
Control method
SVPWM control, V/F control, facility vector control, Speed 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 voltage (P.19), base frequency (P.3) can be arbitrarily set.
Constant torque model, variable torque model can be selected (P.14).
Start torque
150% (1Hz): when use the facility vector control.
Torque boost
The torque boost setting range is 0~30% (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 is 0.01~360s or 0.1~3600s for
selection. Different ‘acceleration/deceleration curve’ model can be
selected (P.29).
DC braking
The DC braking action frequency is 0~1000Hz (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, DC 4~20mA signal setting, 2 voltage input or one voltage and
one current input to select. 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), ‘16-speed
operation’(RL, RM, RH, REX), external thermal relay (OH), reset
(RES), etc. (can be set by the user (P.80~P.84, P.86))
