M-DRIVE

Digital Motor Speed Controller with Integrated 1/4 to 2 HP DC Drive

OVERVIEW

The M-DRIVE is a cost effective integrated controller plus DC drive. The built-in SCR drive can handle up to 2 HP Permanent Magnet DC motors and has an adjustable current limit of 4 to 16 Amps. The digital controller provides closed-loop speed regulation for applications that require the highest level of precision. With zero cumulative error, the M-DRIVE can accommodate demanding electronic gearing applications often found in web handling, and extrusion processes.

FEATURES

No complicated programming required
Speed controller with built-in DC drive for up to 2 HP motors
10 millisecond control loop with zero cumulative error for precision speed ratio control
Adjustable PID gains and Accel/Decel ramps for improved stability control
Built-in LED display can be scaled to engineering units such as feet-per-minute

OPTIONS

Analog Card: 1 Input - Zero to 10VDC or 4-20mA; 1 Output - Zero to +/- 10VDC or 4-20mA; 12 bit resolution
Inverse Set-point Programming: Set-point is a divisor rather than a multiplier. Typical uses include time-in-the-oven conveyors, wraps-per-inch winders, or inverse draw ratio infeed nip rolls.
