Schematic and Interface Definition Standard product: RJ45 type × 2 Pin position from the insertion angle When multiple units are connected in series, when pins 3 and 8 of the last OUT port are short-circuited, and pins 6 and 7 are shortcircuited, it is the access terminal resistance. The IN port does not include a terminating resistor. Setting switch 4. mailing address Users can control up to 30 HSD286pro drives at the same time using RS-485 bus. The drivers communication address is set by a 5-digit DIP switch. The address setting range is 1-32, where address 32 is reserved for the system....

Schematic and Interface Definition 6. Trial run The test run function is used to verify the performance of the drive. Turn OFF the 8th gear switch in the power-off state. Then when the power is turned on without pulse input, turn the SW8 gear dial switch from ON to OFF, and then set OFF to ON from 1 second, then start the trial operation function (the motor rotates at 1 revolution / second Speed cycle forward and backward). 7. Idle current The driver will automatically enter idle current after 500 milliseconds without pulse input to reduce motor heating. The current is restored to the set...

Power Supply The chopper driver continuously changes the size and direction of the motor winding voltage and detects the current to obtain accurate phase current. If both high efficiency and low noise are to be ensured, the driver supply voltage shall be at least 5 times the motor rated phase voltage (that is, the motor rated phase current × phase resistance). If you need the motor to get better high speed performance, you need to increase the driver supply voltage. If power is supplied from a regulated power supply, the supply voltage shall not exceed 72V. If non-stabilized power supply is...

Power Supply / Motor Connection When your application has a large load running at high speed, please contact the company in advance, shield anti - reverse connection function, and external regenerative discharge device. Please note that the positive and negative terminals of the power supply should not be inversely connected when there is no anti-inversely connected function. The driver damage caused by inversely connected power supply cannot be guaranteed. 5. Motor Connection Warning When connecting the motor to the drive, first make sure that the power of the drive is turned off. Make...
