1. Motor Drives supply motor armature voltage from A1 and A2 terminals It is assumed throughout this manual that when A1 is positive with respect to A2 the motor will rotate clockwise CW while looking at the output shaft protruding from the front of the motor If the motor does not spin in the desired direction remove power and reverse the A1 and A2 connections Connect a DC motor to terminals A1 and A2 as shown in Figure 4 on page 12 Ensure that the motor voltage rating is consistent with the drive s output voltage LGP Series Speed Adjust Potentiometer Use a 10K ohm 1 4 W potentiometer for speed control Connect the counter clockwise end of the potentiometer to S1 the wiper to S2 and the clockwise end to S3 If the potentiometer works inversely of the desired functionality e g to increase motor speed you must turn the potentiometer counterclockwise power off the drive and swap the S1 and S3 connections Refer to Figure 4 on page 12 Analog Input Signal Instead of using a speed adjust potentiometer the drive may be wired to follow an analog input voltage signal that is either isolated or non isolated from earth ground Figure 4 on page 12 Connect the signal common to NEG Connect the signal reference 4 to POS A potentiometer can be used to scale the analog input voltage An interface device such as American Control Electronics model ISO202 1 may be used to scale an analog input voltage An analog input2. Remove line power Remove the stall from the motor Remove the ammeter in series with the motor armature if it is no longer needed LGP Series IR Compensation IR COMP The IR COMP setting determines the degree to which motor speed is held constant as the motor load changes Use the following procedure to recalibrate the IR COMP setting 1 Set the IR COMP trim pot to minimum full CCW 2 Increase the speed adjust potentiometer or input voltage signal until the motor runs at midspeed without load for example 900 RPM for an 1800 RPM motor A handheld tachometer may be used to measure motor speed Load the motor armature to its full load armature current rating The motor should slow down While keeping the load on the motor rotate the IR COMP trim pot until the motor runs at the speed measured in step 2 If the motor oscillates overcompensation the IR COMP trim pot may be set too high CW Turn the IR COMP trim pot CCW to stabilize the motor 5 Unload the motor See Figure 8 on page 25 for recommended IR COMP settings LGP101 10 TORQUE IR COMP TORQUE IR COMP TORQUE IR COMP 1HP 90 VDC 10 0 AMPS 1 2 HP 90 VDC 5 00 AMPS 1 4 HP 90 VDC 2 50 AMPS LGP101 2 TORQUE TORQUE IR COMP TORQUE IR COMP IR COMP LGP Series LGP301 10 TORQUE IR COMP TORQUE IR COMP TORQUE IR COMP 2HP 180 VDC 10 0 AMPS 1HP 180 VDC 5 00 AMPS 1 2 HP 180 VDC 2 50 AMPS 1 6 HP 90 VDC
