PSDrive WARNING Do not install the device in environments with risk of explosion, flooding, or the presence of flammable fluids or solids. Ensure sufficient ventilation in the room. Refer to local regulations when selecting the appropriate installation location. WARNING The degree of protection of the device is only ensured if, at the end of the installation, the cover screws and the cable glands have been properly tightened. -
Page 16: Mechanical Assembly Of Size 2 Devices
PSDrive WARNING Do not place any heat-generating elements (outlet filters) on the suction side of the de- vice. Otherwise, dangerous overheating may occur. 6.3. Mechanical assembly of size 2 devices The size 2 devices are equipped with a quick connection system that allows to make both power and signal electrical connections on the fixed part, called "base", while the mobile part, called "power", is applied later. -
Page 17: Motor On-Board Mounting
PSDrive DANGER Be careful not to damage or remove the four metal pins, as this will not only compromise the mechanical coupling between the base and the power, but also the ground connec- tion. 6.4. Motor on-board mounting The device may be installed in place of the motor terminal cover in both horizontal and vertical posi- tions. - Page 18 PSDrive The seal on the base of the device provides protection against the access of water and dust. It is rec- ommended to drill the gasket only at the level of the four fixing holes to the motor case. It is possible to use the same screws and washers with which the terminal cover was fastened to the motor case.

Page 24: Control Cables
PSDrive WARNING Use unshielded cable for input cables and shielded cable for output cables. WARNING Always use cables with appropriate cable lugs, which may be supplied with the product. WARNING For motor cable lengths greater than 5 meters, the use of special output filters, available on request, is recommended. -
Page 25: Electrical Connections
PSDrive WARNING The connection of the Cy filter capacitors to ground may be removed by removing the screws marked with the EMC symbol. In this manner the leakage currents to ground due to the filter are reduced, but the intrinsic EMC compatibility of the device is not guaran- teed and must therefore, be guaranteed externally in another way. -

Page 35: Adjustment Of The Foc Control
PSDrive WARNING During calibration the motor coils are heated by the test current. If the motor is self-venti- lated the absence of motor rotation does not allow the heat to be dispersed by force. It is therefore recommended to allow the motor to cool between one calibration and the next. DANGER During the calibration process the motor remains stationary but is powered for the entire calibration period. -
Page 36: Menu
PSDrive WARNING The incorrect setting of the FOC dynamic may cause: • Speed oscillations if the FOC dynamic is too slow. • Overcurrent or igbt trip alarms if the FOC dynamic is too fast. It is recommended to intervene promptly by appropriately adjusting the "FOC Dynamic" parameter if the conditions listed above are present. -
