Page 16: Motor Mounting
3.4. Motor mounting 3.4.1. Motor mounting By flange and feet By feet For vertical mounting, Please consult us. The load capacity and vibration resistance on shaft are different than for horizontal mounting. 3.4.2. Typical mounting. Warning : The load must be supported by bearings. No additional weight must be mounted on the shaft, even if this weight generates a force lower than the maximum force allowed on the shaft. -
Page 17: Frame Recommendation
3.4.3. Frame recommendation Warning : The user has the entire responsibility to design and prepare the support, the coupling device, shaft line alignment, and shaft line balancing. Foundation must be even, sufficiently rigid and shall be dimensioned in order to avoid vibrations due to resonances. -
Page 18: Coupling
Thermal expansion can also generate strain and load. These forces (axial and radial) must be below the maximum shaft allowed forces (§3.4). Warning : Parker will not be responsible for any motor shaft failure due to excessive strains on the shaft . -
Page 19: Vibration And Bearings Temperature Control
3.4.7. Vibration and bearings temperature control It is highly recommended to implement a vibratory control in accordance with the ISO 10816 standard to detect any sign of mechanical evolution before breakdown. Accelerometers must be located closed to the bearings Accelerometers (vibration sensor) Moreover, it is highly recommended to monitor the bearings temperature. -
Page 20: Bearings
3.5. Bearings The bearings are greased for life. The statistic bearings life is limited from 6000h up to 10000h depending on the way there are assembled and used, it is recommended to control the vibrations every 3000h or to change it once the predicted lifetime is reached. -
Page 21: Cooling
3.6. Cooling In compliance with the IEC 60034-1 standards: 3.6.1. General recommendations Danger: The cooling system has to be operational when the motor is running or energized. Danger: The Inlet temperature and the water flow have to be monitored to avoid any damage. -
Page 22: Additives For Water As Cooling Media
3.6.2. Additives for water as cooling media Please refer to motor technical data for coolant flow rates. The water inlet temperature must not exceed 25°C to get the full performances. The inner pressure of the cooling liquid must not exceed 5 bars. Caution: To avoid the corrosion of the motor cooling system (aluminum or steel), the water must have anti-corrosion additive. -

Page 27: Thermal Protection
3.7. Thermal Protection Protection against thermal overloading of the motor is provided by two PTC thermistors and one KTY temperature sensor (and one more in case of KTY failure) built into the stator winding as standard. The thermal sensors, due to their thermal inertia, are unable to follow very fast winding temperature variations. They achieve their thermal steady state after a few minutes. -
Page 28: Temperature Measurement With Kty Sensors
3.7.2. Temperature measurement with KTY sensors: Motor temperature can also be continuously measured by the drive using a KTY 84-130 thermal sensor built in to the stator winding. KTY sensors are semiconductor sensors that change their resistance according to an approximately linear characteristic. - Page 29 Not limiting example in France: NFC 15-100 or IEC 60364 as well in Europe. Cable selection depends on the cable construction, so refer to the cable technical documentation to choose wire sizes Some drives have cable limitations or recommendations; please refer to the drive technical documentation for any further information.

Please contact Parker for further information. Caution: It might be necessary to fit a filter at the servo-drive output if the length of the cable exceeds 25 m. -
Page 31: Motor Cable
3.8.5. Motor cable The electrical connection on MGV motor is realized by high performance cable. The motor cable section depends on the motor current level. Please refer to the outline drawing to know the cross section (depending of torque/speed characteristics letter code). Caution: The motor cables are designed for high current density, so cable surface can reach or exceed 100°C. -
