ROCKWELL Automation has introduced a new addition to the Reliance range of ac variable speed drives -- the MD60 ac variable speed drive, available through Motion Industries.
The MD60 is available with ratings from 0.18kW to 4kW in single phase 240 volt input, and three phase 415 volt input.

* Zero side clearance for mounting in cabinets and an IP30 kit also available to allow for conduit entry for installation in the field.
With the MD60 start up is simple. The keypad is active out-of-the-box for immediate operation. Only ten basic parameters to configure with an easy to use instruction manual.
Performance features include good low speed torque generation, constant torque generation and constant torque over a 40:1 speed range. Adjustable features include selectable V/Hz settings, dc braking, auto restart control and preset speed settings.
The MD60 provides overload protection at 150% current for one minute and 200% current for three seconds. Carrier frequency ranges from 2 to 16kHz.
