TNi21 WARNING HOT SURFACES The metal surface of the product can reach more than 70°C during use. Avoid all contact with the metal surface. • Do not position inflammable or heat-sensitive components in immediate proximity. • Try to achieve an assembly that allows heat to dissipate efficiently. If these precautions are not taken, the result could be injury or damage to equipment.
TNi21 4.1. Snapshot of the installation procedure The installation procedure is described in the follow sections: Electromagnetic compatibility, EMC Before fitting Fitting the motor Electrical installation Check that these sections have been read and understood and that, subsequently, the motor has been installed correctly.
TNi21 4.3. Before fitting Look for damage Damaged drive systems should not be fitted or used. Check the drive system before fitting and look for visible signs of damage. Cleaning the shaft On leaving the factory, the ends of the motor shafts are coated with film of oil. Where transmission devices are to be fitted by bonding, it may be necessary to remove that oil film and clean the shaft.
TNi21 4.4. Fitting the motor DANGER HOT SURFACES The surface of the motor can reach more than 70°C during use. • Avoid contact with hot surfaces. • Do not position inflammable or heat-sensitive components in immediate proximity. • Try to achieve an assembly that allows heat to dissipate efficiently. •...
TNi21 Installation position The motor can be installed in any position. Installation When fitting the motor on the flange, it must be aligned precisely, both axially and radially. All securing screws must be tightened to the torque prescribed by the application, taking care not to cause any warping. Fitting transmission devices Fitting transmission devices incorrectly could damage the motor.

TNi21 WARNING OVER-VOLTAGES During braking phases, the motor generates over-voltages. • Check that these over-voltages are acceptable to other equipment connected to the same power supply. • Preferably use an external circuit, to limit over-volting In cases where braking is used intensively. If these precautions are not taken, the result could be death, serious injury or damage to equipment.
TNi21 4.5.1. Connecting the holding brake (option) WARNING LOSS OF BRAKING FORCE DUE TO WEAR OR HIGH TEMPERATURE Application of the holding brake while the motor is rotating can cause rapid wear and loss of braking force. • Do not use the brake as a service brake. •...
TNi21 4.6. Production connector The motor is fitted with a silicone plug, as shown in the image below. It protects the connector used during the motor's manufacture. This connector is not intended to be accessed by users of the product. If the plug is removed, the motor will no longer be sealed, allowing fluids and particles to enter the motor, potentially destroying it or causing it to malfunction.
TNi21 5. SWITCHING ON 5.1. Preparations for switching on Before switching on: Check that the mechanical installation is correct. Check that the electrical installation has been done professionally: in particular, check the connections on protective conductors and earth connections. Ensure that all connections are correct and sound and that screws are properly tight.

TNi21 8.1.1.1. Proposed ballast circuit diagram. The arrangement below dissipates braking energy into a resistor, thus limiting the over-voltage at the motor terminals. Figure 8 8.1.1.2. Sizing resistor R12 (R Ballast The lower the resistor value, the higher the braking current. Typical values are in the region of several Ohms. Where V is the speed of rotation in rpm and J the inertia in kg.m².
TNi21 8.1.1.3. Selecting the cut-off voltage The cut-off voltage should be selected: According to the power supply According to other devices connected to the same power supply. If your power supply does not tolerate current feedback, fit a diode in series upstream of the ballast circuit to protect it.
TNi21 8.2. Protective devices DANGER PROTECTIVE DEVICES The product includes internal protection devices which cut the power supply to the motor, when activated. Since the motor is no longer being controlled, driving forces may drop. • The manufacturer of the system is responsible for complying with all the safety rules applicable in the event of product failure.
TNi21 8.2.3. Current limiting The product has an internal current limiter. This limiter operates directly on the motor through hardware. The limiter automatically clips the current to the peak current value in the motor phases. If the limit is reached, the motor's performance is reduced. This product is not designed to operate continuously at this limit (see the "Electrical data"...

CAUTION EARTHING THE OUTPUTS The accidental earthing of the outputs or connecting them to a capacitive load will result in them being destroyed. Before powering up the motor, check that the outputs are wired correctly.
TNi21 9. OPERATING MODE 9.1. Preliminaries DCmind motors with TNI21 integrated electronics are designed to operate by regulating the speed with an adjustable torque limiter. These electronics operate in trapezoidal switching mode. There are two types of board available in the catalogue: Version with proportional 0-10V inputs Version with proportional PWM inputs The speed is controlled by a factory-set PID to allow a wider operating range.
TNi21 9.2.4. Function E4 - Torque limiter set-point The torque limiter proportional input is linear throughout its range. The corresponding scale varies according to the type of motor: Drive basis Min terminal (0V or 0%) Max terminal (10V or 100%) 80140_TNI21 360 mN.m 35 mN.m...

Addresses of after-sales service points Contact your distributor The list of distributors can be accessed via the Crouzet Automatismes web site www.crouzet.com 11.2. Storage Motors should only be transported and stored in a dry environment, free from dust and protected from vibration.
TNi21 The holding brake is bedded in before it leaves the factory. If the holding brake is not called upon to do any mechanical work for a long period, some of its parts could corrode. If the holding brake does not provide the holding torque specified in its technical characteristics, it might be necessary to bed it in again.
TNi21 11.6. Terms and abbreviations Level of protection The level of protection is a standardised rating used for electrical equipment ans intended to describe the protection against the ingress of solids and liquids into the motor enclosure, e.g. IP54M. The M indicates that testing was done with the motor running.
