BMS42-61 and BMS42-504 - planetary DC gear drives with RS-485
BMS42 is a DC complete brush motor drive with planetary gearhead, with RS-485 communication interface. It is reversible, maintenance-free. We offer two standard reduction ratios - 1/61 - BMS42-61 and 1/504 - BMS42-504. The drives consist of planetary gearmotor SM42P and controller BMSD.
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.
