Setting up & Commissioning 4-2514C Product ManualCurrent CalibrationCurrent Calibration is achieved using the BCD switches SW2, 3 and 4 where SW2 represents the'Tens'; SW3 represents the 'Units' and SW4 represents the 'Tenths'. Thus a 16.5 amp calibrationis achieved by setting switch SW2 to 1, SW3 to 6, and SW4 to 5.Please note that incorrect adjustment of these switches will cause excessive current to flowwhich may cause damage to the motor and the controller. The absolute maximum settingwhich can be set is 39.9 amps, this exceeds the Maximum Controller rating in all builds.POTENTIOMETERSP1 Ramp Up Rate Rotate Clockwise for Faster Acceleration toSet Speed.(Linear :- 1 to 40 seconds)DefaultSetting:Midway540/1 P1P2 Ramp DownRateRotate Clockwise for Faster Deceleration toSet Speed.(Linear :- 1 to 40 seconds)Midway 540/1 P2P3 Speed LoopProportionalOptimises Speed Loop Stability byincreasing gain.Midway 540/1 P5P4 Speed LoopIntegralOptimises Speed Loop Stability byincreasing integral time constant.Midway 540/1 P6P5 I Limit Rotate Clockwise to increase MaximumOutput Current.With no additional connection to Torque /Current Limit Terminal T7, the Upper Limitis 110%.
