；
DC braking current:
constant torque 0.0~120.0%
；
variable torque 0. 0~90.0%
Direct current brake time: 0.0~30.0s
；
realize quick brake without direct
current brake initial waiting time
Inching control
Inching frequency range:0.00Hz~50.00Hz
Inching acceleration and deceleration time range:0.0s~3600.0s
Process closed
loop PID
The process closed loop control system can be conveniently realized
Simple PLC,
multi-stage
instruction
At most 16 speed stages can be easily realized through built-in simple
PLC or X terminal.
Automatic voltage
regulation
When the power grid voltage fluctuates, the output voltage can be
automatically kept stable.
Overflow,
over-voltage and
stall control
The current and voltage during operation are automatically limited to
prevent frequent over-current and over-voltage tripping.
Automatic fast
current limiting
Minimize over-current faults and protect the normal operation of the
drive.
Torque limit and
control
"Excavator" feature automatically limits torque during operation to
prevent frequent over-current tripping; in vector control, torque control
