Speed Controls for Dancer Pot Applications
These controls are designed for applications that call for dancer
pot control. They feature electronic adjustment of offset and
span, to replace the cumbersome linkage adjustment common
to installations of this type.

- Page 4 The control is factory calibrated with OFFSET at 0° and SPAN at 300°. The MAX SPD trimpot is adjusted to 85V DC (MM21036A) and 170V DC (MM22036A), at no load. Calibrate the drive using the following procedure: Set the MIN SPD and OFFSET trimpots to zero (full CCW).

Page 5: Minimum Speed (Min Spd)
MM21036A/MM22036A INSTALLATION GUIDE OFFSET OFFSET sets the dancer pot wiper position at which the motor begins to run. This is expressed as the angle of the wiper relative to its fully CCW position. With these controls, the of- fset of the wiper may be set as high as 290° before the motor will run. -
Page 6: Maximum Speed (Max Spd)
MM21036A/MM22036A INSTALLATION GUIDE SPAN SPAN is the angle through which the dancer pot wiper must rotate to cover the full speed range that the application requires. The motor will not increase speed at any setting past this angle. The minimum span of the wiper to obtain rated output from these controls is 10°. - Page 7 MM21036A/MM22036A INSTALLATION GUIDE To calibrate IR COMP (exact calibration): Turn the IR COMP trimpot full CCW. Set the dancer potentiometer until the motor runs at midspeed without load (for example, 900 RPM for an 1800 RPM motor) A hand held tachometer may be used to measure motor speed.

Page 8: Torque Limit (Torque)
Although TORQUE is set to 120% of maximum drive current rating, continuous operation beyond that rating may damage the motor. If you intend to operate beyond the rating, contact your Minarik representative for assistance. The TORQUE setting determines the maximum torque for accelerating and driving the motor. - Page 9 MM21036A/MM22036A INSTALLATION GUIDE Set the dancer potentiometer to the OFFSET position. Remove power from the drive. Remove the lock from the motor shaft. 10. Remove the ammeter in series with the motor armature. The control is now calibrated.
