Motor controller with RS-485 interface BLSD-20Modbus

three-phaseBLDCclosed-loop

BLSD‑20Modbus is a brushless dc motor controller for three-phase motors with Hall sensors. This intellegent controller can be pre-programmed according to the system demands and work as a standalone drive, can operate as a slave in RS-485 network or operate as a simple DC brushless motor controller for speed control. BLSD-20Modbus provides position control based on Hall sensors information, speed regulation, current limiting function. Thanks to the current limiting function, BLSD-20Modbus protects the motor from overloads. Maximum rated current can be limited according to the brushess motor model (up to 20A). This controller is used for DC brushless motors 24V, 36V, 48V with rated power up to 1000W. BLSD-20Modbus can be used as a standalone unit or can be controlled by a master device in RS-485 network. The controller is programmable, the programming software is easy to use and free of charge. BLSD-20Modbus features and capabilities the unit can be controlled via the RS-485 interface using the Modbus RTU or ASCII protocol or by external signals supplied to the controller inputs; motor rotation speed can be set via Modbus or external analog signal; motor position can be set via Modbus; setting the values ​​of acceleration and deceleration; setting the maximum value of the motor current (motor overload protection); drawing up a user control program, starting the program by command via Modbus or automatically when the drive is powered up; programming inputs IN1 and IN2, which can also be used as START / STOP and REVERSE / DIRECTION signals;
