frequency setting
0.1~120.00Hz
Resolution
of frequency
setting
․
Digital Keypad: 0.01Hz
․
Analog signal: 0.06Hz / 60Hz
Resolution
of output
frequency
0.01Hz
Frequency setting
signal
DC 0~10V, 4~20mA.
Overload
protection
120% of drive rated output current for 1 minute.
DC braking
․
Time of DC braking after start / before stop: 0~20.0sec
․
DC braking frequency at stop: 0.1~60Hz
․
DC baking level: 0~150% of rated current
Braking torque
Approximately 20%(with the external braking resistor
connected, braking torque is approximately 100%).
Acceleration/
deceleration time
․
0sec(coast to stop), 0.0~3200.0sec(independent setting of
the acceleration / deceleration).
․
The setting of accel/decel time from 0 to 60Hz is 0.015sec ~
19,200,000sec(222 days).
V/F pattern
․
Linear, Square curve, 1.7
th
power curve, 1.5
th
power curve.
․
V/F pattern (2 V/F points).
․
V/F pattern can be adjusted by analog input (Variable
voltage (V) adjustment of V/F pattern for acceleration /
deceleration).
Other functions
slip compensation, auto-torque compensation,
auto-adjustment for output voltage stability, auto-operation for
energy-saving, auto-adjustment of switching frequency, restart
after instantaneous power failure, speed tracing, overload
detection, PID control, acceleration/deceleration switch, fan
control, parameters copy, sequential control, communication
control, over pressure protection, pump protection, ON/OFF
mode.
