8.1 Trial Operation(2) Operating Procedure in Speed Control Mode (Pn000 = n.0)The following circuit is required: External input signal circuit or equivalent.+24V/S-ONP-OTSERVOPACKCN1474042N-OT43+0VV-REFV EV E : Max. voltage (12 V)56Step Description Check Method and Remarks1 Check the power and input signal circuits again, andcheck that the speed reference input (voltagebetween the V-REF and SG) is 0 V.Refer to the above figure for input signal circuit.2 Turn ON the servo ON (/S-ON) input signal. If the servomotor rotates at extremely slow speed,refer to 8.5.3 Adjusting Offset, and use the referencevoltage offset to keep the servomotor from moving.3 Generally increase the speed reference input voltagebetween V-REF and SG from 0 V.The factory setting is 6 V/rated rotation speed.4 Check the speed reference input to the SERVO-PACK (Un000 [min-1]).Refer to 7.1.3 Basic Mode Selection and Operation forhow it is displayed.5 Check the Un000 (motor speed [min-1]. Refer to 7.1.3 Basic Mode Selection and Operation forhow it is displayed.6 Check that the Un001 and Un000 values in steps 4and 5 are equal.7 Check the speed reference input gain and motorrotation direction.8 When the speed reference input is set to 0 V andservo OFF status enters, the trial operation for servomotorwithout load is completed.Change the speed reference input voltage and checkthat Un001 and Un000 values are equal for multiplespeed references.Refer to the following equation to change the Pn300(speed reference input gain).Un001=(voltage between V-REF) [V] × Pn300 [300min-1/6V]To change the motor rotation direction without changingpolarity for speed reference input gain, refer to8.3.2 Switching the Servomotor Rotation Direction.Perform the operation from step 2 again after themotor rotation direction is changed.−88-11
