Description
Thank you for purchasing RMCS-2301 50V 20A servo drive/controller. The position of the DC servo motor
can be controlled by a STEP/PULSE and DIRECTION digital interface similar to stepper motors.
The PULSE/STEP, DIRECTION inputs are optically isolated. Both inputs work with 2.5V, 3.3V or 5V logic
drive signals. The input drive current is 5mA at 2.5V so almost all logic family (74LS, 74HC, etc.) can be
used to drive these inputs. Each input provides individual anode and cathode connections to the opto-
isolator allowing for multiple input drive interfaces.
