HAZARD

HEAT

KEE

It is possible for a drive to run at full speed as a result of

a component failure. Minarik strongly recommends the

installation of a master switch in the main power input to stop

the drive in an emergency.

Circuit potentials are at 115 VAC or 230 VAC above earth

ground. Avoid direct contact with the printed circuit board or

with circuit elements to prevent the risk of serious injury or

fatality. Use a non-metallic screwdriver for adjusting the

calibration trimpots. Use approved personal protective

equipment and insulated tools if working on this drive with

power applied.

Most non-regenerative, variable speed, DC drives control current

flow to a motor in one direction. The direction of current flow is the

same direction as the motor rotation. Non-regenerative drives

operate in Quadrant 1, and also in Quadrant 3 if the drive is

reversible (see Figure 1). Motors must stop before reversing

direction. Unless dynamic braking is used, non-regenerative drives

cannot oppose an overhauling load, and cannot decelerate a load

faster than coasting to a lower speed.

Regenerative drives operate in two additional quadrants: Quadrant

2 and Quadrant 4. In these quadrants, motor torque is in the

opposite direction of motor rotation.

This allows regenerative drives to reverse a motor without

contactors or switches, to control an overhauling load, and to

decelerate a load faster than it would take to coast to a lower

speed.
