4 Trial Operation4.3.1 Inspecting Connection and Status of Input Signals4-44.3.1 Inspecting Connection and Status of Input SignalsCheck the items in step 1 before trial operation of the servomotor under speed control and position control ref-erences from the host controller.Check the connection and status of input signals using the following procedure.CAUTIONBefore performing trial operation of the servomotor alone under references from the host controller, be surethat the servomotor has no load (i.e., the coupling and belt are removed from the servomotor) to preventunexpected accidents.CN1To host controllerTo main circuitpower supplyTo controlpower supplySecure the motor flange tothe machine, but do notconnect the motor shaft tothe load shaft.Step Operation Reference1Connect the necessary input signals to the I/O signal connector (CN1) under the following con-ditions.• It must be possible to input servo ON signal (/S-ON).• The forward run prohibited (P-OT) and reverse run prohibited (N-OT) input signals must beON (L level) (i.e., the servomotor must be able to run in forward and reverse).Settings: CN1-42 and CN1-43 must be ON (low) or Pn50A.3 and Pn50B.0 must be set to 8 todisable the forward and reverse run prohibited function.Note: Return the settings to the previous ones after completing trial operation.• Make sure that no reference is being input.• If Pn002.2 is set to 1, the absolute encoder can temporarily be used as an incremental encoder,which makes it possible to perform trial operation of the servomotor without Fn008 and SENsignal settings.Connect a safety function device to CN8 when using the safety function.For the connecting method, refer to (1) Connecting a Safety Function Device.Refer to the following connec-tion diagrams.3.3.3 Example of I/O SignalConnections in Speed Control3.3.4 Example of I/O SignalConnections in Position Con-trol3.3.5 Example of I/O SignalConnections in Torque Control5.9 Absolute Encoders5.11 Safety Function3.3.2 SERVOPACK SafetyFunction Signal (CN8) Namesand Functions2 Connect the connector of the host controller to the I/O signal connector (CN1) on the multi-winding drive unit. –
