Digital output 2 channel, Optocoupler isolation / open collector output / rated current 20mA (DO,DHO)
Digital pulse output 2 channels / optocoupler isolation / open collector pulse (frequency or PWM) output (O, DHO), including 1 high-speed 
pulse output, and the maximum output pulse frequency can reach 100kHz
Relay output 2 channel,Normally open and normally closed contact, 250VAC-3A
Communication mode Standard MODBUS-485 communication protocol
Control characteristics control mode V / F control: no PG vector control (SVC); with PG vector control (SVC)
Frequency setting mode Keyboard setting, analog setting, pulse setting, communication setting and others
Frequency control range 0.01~500Hz
Frequency control accuracy Digital setting: 0.01Hz; Analog setting: maximum frequency x0.025%
Speed regulation ratio 1:200 ( SVC ) ;   1:1000(FVC)
Steady speed accuracy ±0.5% ( SVC ) ;  ±0.02% ( FVC ) ;
Acceleration and deceleration time 1.0 ~ 3600.0s (acceleration and deceleration time can be set separately and S characteristic can be switched)
Inching control Inching frequency range: 0.00hz ~ 100Hz; Jog acceleration and deceleration time: 0.0s ~ 3600.0s
Starting torque 0.5Hz 150% (SVC) is adjustable, and the capacity of frequency converter shall be considered; 3.0Hz 100%(V/F)
Torque boost Automatic torque lifting; Manual torque increase 0.1% ~ 30.0% adjustable
Braking torque Braking resistance braking (125%), DC braking (20%)
DC braking Braking time: 0.0s ~ 36.0s; Braking current: 0.0% ~ 100.0%
Timing control Timing range: 0.0min ~ 6500min
PID control With built-in PID function, it is convenient to realize process closed-loop control
V / F curve Linear, multi-point user-defined curve, 1.1 ~ 2.0 arbitrary power-down curve
Multistage speed control Built in simple PLC can control the maximum 16 speed frequency logic
Carrier adjustable 1.0~16kHz ,adjusted according to the module temperature
Frequency setting signal -10 ~ + 10, 0 ~ + 10, 4 ~ 20mA, high frequency pulse, PWM pulse
Protection function Overload capacity G:60s-rated current x 150%;  3s-rated current x 200%; P:60s-rated current x 120%;  1s-rated current x 150%
Instantaneous overcurrent / short circuit protection More than 200% of the rated output current, automatically cut off the output
Overvoltage / undervoltage protection When the bus DC voltage is too low (360V) or too high (800V), the motor stops freely (except braking)
Open phase protection In case of phase loss at the input or output end, the motor stops freely
Overheat protection When the radiator temperature is ≥ 85 ºC , the motor will stop automatically; The temperature protection threshold 
can be set freely according to the ambient temperature
Motor protection Analog input can be connected with temperature sensor input (PT100, PT1000) to realize motor overheating protection
Stall protection Prevent stall during acceleration or deceleration or operation (working current can be set)
Grounding protection by current sensor
Instant stop The load feedback energy compensates for the voltage reduction and maintains the continuous operation of the frequency 
converter in a short time
