8.1 Trial Operation(3) Operating Procedure in Position Control Mode (Pn000 = n.1)The following circuit is required: External input signal circuit or equivalent.Reference pulseaccording toparameterPn200.0 setting+24V/S-ONP-OTN-OTCLRPULSPulse reference/PULSSIGN/SIGNSERVOPACKCN14740424315781112Step Description Check Method and Remarks1 Match the reference pulse form with the pulse outputform from the host controller.2 Set the reference unit and electronic gear ration sothat it coincides with the host controller setting.3 Turn ON the power and the servo ON (/S-ON) inputsignal.4 Send the pulse reference for the number of motorrotation easy to check (for example, one motor revolution)and with slow speed from the host controllerin advance.5 Check the number of reference pulses input to theSERVOPACK by the changed amount before andafter the Un00C (input reference pulse counter)[pulse] was executed.6 Check the actual number of motor rotation [pulse]by the changed amount before and after the Un003(rotation angle 1) [pulse] was executed.7 Check that steps 5 and 6 satisfy the following equation:Un003=Un00C × (Pn202/Pn203)8 Check that the motor rotation direction is the sameas the reference.9 Input the pulse reference with the large number ofmotor rotation from the host controller to obtain theconstant speed.10 Check the reference pulse speed input to the SER-VOPACK using the Un007 (input reference pulsespeed) [min -1 ].Set the reference pulse with Pn200=n.×. Referto 8.6.1 (2) Setting a Reference Pulse Form.Set the electronic gear ratio with Pn202/Pn203. Referto 8.6.2 Setting the Electronic Gear.−Set the motor speed of several 100 min -1 for the referencepulse speed because such speed is safe.Refer to 7.1.3 Basic Mode Selection and Operation forhow it is displayed.Un00C (input reference pulse counter) [pulse]Refer to 7.1.3 Basic Mode Selection and Operation forhow it is displayed.Un003 (rotation angle 1) [pulse]−Check the input pulse polarity and input referencepulse form. Refer to 8.6.1 (2) Setting a ReferencePulse Form.Set the motor speed of several 100 min -1 for the referencepulse speed because such speed is safe.Refer to 7.1.3 Basic Mode Selection and Operation forhow it is displayed.Un007 (input reference pulse speed) [min -1 ]The number of input reference pulses (Un00C) can be obtained from the following equation.8Un007(input reference pulse speed) input reference pulse pulses/S × 60 ×Pn202 1×13Pn203 2 (8192)Reference input ppmElectronicgear ratio* The encoder pulse differs depending on the model of the servomotor used.Encoderpulse ∗8-13
