1.2. Safety 1.2.1. Principle To operate safely, this equipment must be transported, stored, handled, installed and serviced correctly. Following the safety instructions described in each section of this document is mandatory. Servomotors usage must also comply with all applicable standards, national directives and factory instructions in force.
Page 32
Mechanical hazard Servomotors can accelerate in milliseconds. Running the motor can lead to other sections of the machine moving dangerously. Moving parts must be screened off to prevent operators coming into contact with them. The working procedure must allow the operator to keep well clear of the danger area.
1.2.3. Safe Torque Off function The safe torque off function in accordance with the standards EN ISO 13849-1 : 2006 and EN 61800-5-2 : 2006 is an electronic system set up on some drives certified by a notified body.

2.6. Product Code The EX servomotors are defined by its electrical and mechanical characteristics, by its accompanying accessories and by any customer specificity. This information is coded and entered in the “Type” column on the manufacturer’s plate for the basic codification; the specificities are entered in a separate column (Check option available for each certification).
EX servomotors are designed to operate with a maximum ambient temperature of 40°C. In case of using with an ambient temperature above 40°C and less or equal than 60°C, a derating of performances is applied according to data recommended by Parker. 3.1.4.

Furthermore, each Mi and speed associated Ωi of the duty cycle has to be located in the operational area of the torque vs speed curve. Torque rms. Ωi Ωk Ω Ωn Speed 3.1.5. Servo drive selection Selection of drive depends on its rated power, rated current and its mode selection which leads to the maximal current duration.
Page 44
AC890 PARKER drive example: The rated current provided by the AC890 drive depends on its rated power and its mode selection. “Vector mode” is used for induction motors while “Servo mode” is used for brushless AC motors. With EX motors the power is usually < 37 kW, the rated current corresponds to 100 %.
Page 45
Example n°1 : The application needs: - a rms torque of 7 Nm at the rms speed of 2000 rpm, - an acceleration torque of - a maximal speed of 2800 rpm. Selection of the motor: The selected motor is the type EX620EAO. The nominal speed is equals to 4300 rpm.
Page 46
Example n°2 : This times; the application needs : - a permanent torque of 5 Nm at low speed, - a rms torque of 5 Nm at the rms speed of 1890 rpm, - an acceleration torque of 7.6 Nm, - a maximal speed of 2800 rpm.
3.1.6. Current limitation at stall conditions (i.e. speed < 3 rpm) Recommended reduced current at speed < 3 rpm: reduced Warning: The current must be limited to the prescribed values. If the nominal torque has to be maintained at stop or low speed (< 3 rpm), imperatively limit the current to 70% of I (permanent current at low speed), in order to avoid an excessive overheating of the motor.

3.2.12. Voltage withstand characteristics of EX series The motors fed by converters are subject to higher stresses than in case of sinusoidal power supply. The combination of fast switching inverters with cables will cause overvoltage due to the transmission line effects. The peak voltage is determined by the voltage supply, the length of the cables and the voltage rise time.
3.2.13. Voltage and current during the operating The EX motors can carry ATEX, IECEx, CCC and UL certification and due to this certificate, they are subjected to strict rules regarding their use. One of such rules is the us of a servoamplifier that meets specific characteristics.

3.6. Cooling In compliance with the IEC 60034-1 standards: The ambient air temperature shall not be less than -20°C and more than 40°C. It is possible to use the motors in an higher ambient temperature between 40°C to 60°C but with an associated derating to the motor performances. Warning: To reach the motor performances calculated, the motor must be thermally well connected to a aluminium flange with a dimension of 400 mm x 400 mm and with a thickness of 12 mm.
3.7. Thermal Protection The drive guarantees a 1st level of safety but it is not sufficient. Safety is guaranteed by the independent relay system described in the connection diagram (§4.3.3) which constitutes an independent protection circuit meeting safety classification SIL2 in accordance with the standard IEC 61508.

4. COMMISSIONING, USE AND MAINTENANCE 4.1. Instructions for commissioning, use and maintenance 4.1.1. Equipment delivery All servomotors are strictly controlled during manufacturing, before shipping. While receiving it, it is necessary to verify motor condition and if it has not been damaged in transit.
4.1.3. Storage Before being mounted, the motor has to be stored in a dry place, without rapid or important temperature variations in order to avoid condensation. During storage, the ambient temperature must be kept between -20 and +60°C. If the torque motor has to be stored for a long time, verify that the shaft end, feet and the flange are coated with corrosion proof product.
4.2.3. Preparation Once the motor is installed, it must be possible to access the wiring, and read the manufacturer’s plate. Air must be able to circulate around the motor for cooling purposes. Clean the shaft using a cloth soaked in white spirit or alcohol. Pay attention that the cleaning solution does not get on to the bearings.
Warning : a misalignment of the coupling device makes stress and load on the motor shaft depending the rigidity of the installation. The variations of the temperature makes stress and load due to the dilatation. These loads (axials and radiale) do not exceed the load written (§...
