BM71-91 - DC planetary gear drive

BMS71-91 is a complete DC gear drive with planetary gearmotor SM71P and DC motor controller BMSD with RS-485 communication interface. The drive is 24VDC voltage.

The BMSD controller, included to the complete drive, adjust motion speed, direction, acceleration and deceleration. The motion control provided by input signals or by commands via RS-485 interface.

Motor speed is adjusted by analog voltage signal 0-5VDC, by potentiometer - internal (there is a built-in potentiometer on the case of the BMSD controller) or external (can be connected to the controller) or by a command via RS-485. Start/stop and direction are digital signals, also can be controlled via RS-485. The inputs are duplicated by buttons on the controller's case. Inputs (and buttons) handle a signals as per the front edge or signal level. The version depends on a controller firmware - please, ask when order.
