G-style machine: 150% rated current at 60s; 180% rated current at 3s
P -style machine: 120% rated current at 60s; 150% rated current at 3s
Automatic torque promotion; manual torque promotes by 0.1%~30.0%
Three ways: linear type; multipoint type; N
(1.2 power, 1.4 power, 1.6 power, 1.8 power, 2 power)
2 ways: full separation, semi-separation
Linear or S-curve acceleration/deceleration way.
Four kinds of acceleration/deceleration time
Acceleration/deceleration time range: 0.0~6500.0s
DC braking frequency: 0.00Hz~maximum frequency; Braking time:
0.0s~36.0s braking action; Current value: 0.0%~100.0%
Inching frequency range: 0.00Hz~50.00Hz;
Inching acceleration/deceleration time 0.0s~6500.0s
Realize 16-stage velocity operation at most through built-in PLC or
control terminal
Easy to realize process control, closed-loop control system
voltage
Limit current/voltage automatically during operation, prevent frequent
tripping caused by over-current and over-voltage
" Nawy " character limit torque during operation,
prevent frequent overcurrent tripping, closed-loop
vector mode can realize torque control
