5 Trial Operation (Checking Servomotor Operation)5-25.1 OutlineThe trial operation described here is a JOG operation for servomotors not connectedto machinery (without a load). The purpose of this trial operation is to check whetherthe SERVOPACK and servomotor are properly connected and whether the servomo-tor is operating normally.To conduct trial operation executed from the host controller for the servomotor with-out load, or for the servomotor connected to the machine, refer to the following man-uals.• Σ-V Series User's Manual Design and Maintenance Rotational Motor/AnalogVoltage and Pulse Train Reference (SIEP S800000 45)• Σ-V Series User's Manual Design and Maintenance Rotational Motor/MECHA-TROLINK-II Communications Reference (SIEP S800000 46)• Σ-V Series User's Manual Design and Maintenance Rotational Motor/CommandOption Attachable Type (SIEP S800000 60)• Σ-V Series User's Manual Design and Maintenance Rotational Motor/MECHA-TROLINK-III Communications Reference (SIEP S800000 64)5.2 Inspection and Checking before Trial OperationTo ensure safe and correct trial operation, inspect and check the following itemsbefore starting trial operation. ServomotorsInspect and check the following items, and take appropriate measures before per-forming trial operation if any problem exists.• Are all wiring and connections correct?• Are all nuts and bolts securely tightened?• If the servomotor has an oil seal, is the seal undamaged and is the motor oiled?• If the servomotor has a brake, is the brake released beforehand? To release thebrake, apply the specified voltage (24 VDC or 90 VDC). The following diagramshows an example of the circuit wiring needed to release the holding brake before atrial operation.CAUTION• Conduct trial operation on the servomotor alone with the motor shaft discon-nected from the machine to avoid any unexpected accidents. If it is unavoidableto perform trial operation while connected to a machine, then always make surethat an emergency stop can be immediately executed.
