1. Product designation
Brushless controllers BLSD-20 and BLSD-50 are electronic devices to operate and control brushless
synchronous 3-phase dc motors with
Hall encoder. Motor operation parameters are set either by commands via communication interface RS-485
or via controller’s inputs.
2. Technical characteristic
Controllers are designed to control speed, direction, smooth start and stop of brushless motors by
commands via communication interface RS-485 or by input signals “START/STOP”, “REVERSE”, .analog
“SPEED” and “ACCELERATION”.
