2.4 Conducting a Test Run472.4.5 Minimum User Constants Required and Input Signals1) This section describes the minimum user constants that must be set to conduct a test run.For details on how to set each user constant, refer to 4.1.5 Operation in User ConstantSetting Mode.a) Servopack in speed/torque control modeCn-03 Speed reference gainCn-0A Dividing ratio settingb) Servopack in torque control modeCn-13 Torque reference adjustment gainCn-0A Dividing ratio settingc) Servopack in position control modeCn-02 bits 3, 4 and 5 Reference pulse form selectionCn-24 Electronic gear ratio (numerator)Cn-25 Electronic gear ratio (denominator)After changing the Cn-02 setting, always turn the power OFF, then ON. This makesthe new setting valid.2) If the specified direction of rotation differs from the actual direction of rotation, the wiringmay be incorrect. In this case, recheck the wiring and correct it accordingly. Then, if thedirection of rotation is to be reversed, set the following user constant:Cn-02 (bit 0) Reverse rotation modeAfter changing the Cn-02 setting, always turn the power OFF, then ON. This makes thenew setting valid.3) The following table lists the minimum input signals required to conduct a test run. For de-tails of each input signal, refer to the relevant page.Signal Name PinNumber FunctionS-ON (servo ON) 1CN-40Switching between motor ON and OFF status.Thememory switch can be used to eliminate the need forexternal short-circuit wiring (see page 132).P-OT(forwardrotationprohibited)1CN-42 Overtravel limit switchThe memory switch can be used to eliminate theN-OT(revererotationprohibited)1CN-43The memory switch can be used to eliminate theneed for external short-circuit wiring (see page 54).2
