D to minimize oscillations is system dependent. 4. If dancer arm oscillations cannot be eliminated, turn the P pot counter-clockwise and repeat step 3. Calibration is complete, and the DFC-90 is ready for operation. www.maxcessintl.com MAGPOWR DFC-90 MI 850A265 1 G... - Page 14 (terminals 17 and 18). The length of time the increased torque is applied is adjusted by the STOP TIME pot. Using the stop multiplier feature in dancer mode could cause the dancer to oscillate while the machine is stopping. www.maxcessintl.com MAGPOWR DFC-90 MI 850A265 1 G...
