The steps are specified on the condition thatinput signal wiring for the position control has been completed according to 4.3.1 Inspecting Connection and Sta-tus of Input Signals.Step Operation Reference1 Recheck the power supply and the input signal circuits, and turn ON the SERVO-PACK control power supply.3.2.4 Example of I/O Sig-nal Connections in Posi-tion Control2 Set the reference pulse form with Pn200.0 according to the output pulse form of thehost pulse reference form.5.4.1 Basic Settings forPosition Control3 Set the reference unit, and then set the electronic gear ratio according to the host con-troller. The electronic gear ratio is set in Pn20E and Pn210. 5.4.4 Electronic Gear4 Turn ON the main circuit power supply of the SERVOPACK. 5 Turn ON the servo ON (/S-ON) input signal. 6Output a low-speed pulse reference for an easy-to-check number of movements fromthe host controller. 7Check the number of reference pulses input to the SERVOPACK from the changes inthe input reference pulse monitor before and after the reference.The input reference pulse can be checked with Un00C.8Check the actual number of motor movements from the changes in the feedbackpulse monitor before and after the reference.The feedback pulse can be checked with Un00D.9 Check that step 7 and step 8 satisfy the following formula.Un00D = Un00C (Pn20E/Pn210) 10Check that the servomotor is moving in the direction specified by the reference.Note: To switch the motor movement direction without changing the polarity of theinput pulse, refer to 5.2.3 Servomotor Movement Direction.5.2.3 Servomotor Move-ment Direction11 Input a pulse reference for a comparatively large number of motor movements fromthe host controller so that the servomotor will move at a constant speed. 12Check the reference pulse speed input to the SERVOPACK from the input reference pulse speed monitor (mm/s).The input reference pulse speed can be checked with Un007.Note: Obtain Un007 from the following formula.13 Check the motor moving speed (mm/s). The motor moving speed can be checkedwith Un000. 14 Check that the values in step 12 and step 13 (Un007 and Un000) are equal to eachother. 15 Stop the pulse reference and turn OFF the servo ON signal (/S-ON). Note: To ensure safety, set the reference pulse speed so that the motor speed will bearound 100 mm/s.Un007 input reference pulse speed㨇pulses/s㨉 Pn210Pn20E10001Scale pitch [μm]Number of divisions× ×Electronicgear ratioLinear scale resolution47
