Speed Controls, M-Drive

The M-drive is a cost effective way to control DC motors up to 2 HP. This digital motor speed control has built-in drive. It connects directly to DC motors, eliminating the expense of buying and installing a separate drive. The easy-to-operate M-Drive provides stand-alone control of a single motor or accurate coordination of more complex multi-motor drive systems. It provides closed-loop speed regulation with zero cumulative error (follower mode). Other features: preset speeds – the M-Drive has four preset speeds or ratios to allow quick change of conditions; direct, follower and computer supervised operating modes and four alarms for limit and deviation set-points are available; readouts are displayed in engineering units with command and display easily scalable from the front panel; a lock-out and set-point limit are provided for security; programmable keypad – a sealed keypad for very simple, flexible programming; dedicated keys are provided for Set Speed and Tach; set-points can be entered numerically or
