The LTS350D/LTE350D servo amplifiers are system components designed to supply and control EC motors, with speed and current regulation managed within the amplifier itself. These devices are intended for integration into machines or systems, or for assembly with other components to form a complete machine or system. They are specifically designed for installation in a BT356 card rack or an SB35x system box, facilitating connection to a tightening spindle or an ErgoSpin hand-held nutrunner. The products are not ready-for-use machines and may only be commissioned once integrated into a compliant machine/system that adheres to the EC Machinery Directive.

Function Description:

The core function of the LTS350D/LTE350D servo amplifiers is to provide power and control to EC motors. This includes regulating both the speed and current of the motor. The device features a graphic LC display that shows result values such as torque, angle, gradient, and time, as well as error codes. The display is permanently backlit (LED) and shows texts in 4 lines, each with 8 characters. The contrast of the display can be adjusted via the BS350 operating system.

The servo amplifiers include several interfaces for connectivity and control:

XDS1 interface (for LTE350D): This 11-pin connection socket is used for the ErgoSpin hand-held nutrunner. It provides power supply for the motor, logic supply, and transmits interface signals. Key signal assignments include CAN-L, CAN-H, 24V, GND, HS, SAMI-B, SAMI-A, and motor phases U, V, W, along with protective earth/shield.
XDS2 interface (for LTS350D): This 14-pin socket connects to a tightening spindle via a spindle connecting cable. It supplies power for the motor and transmits interface signals. Signal assignments include PE conductor, motor phases U, V, W (230 VAC/12 Aeff), driver power supply (12 VDC), serial spindle data CAN low/high (ISO 11898), incremental encoder channels 1 and 2 (12 VDC), reference potential logic, index impulse (12 VDC), 24V spindle power supply (24 VDC), motor identifier and motor temperature error (12 VDC), and auxiliary start switch for motor contactor (24 VDC).
XDN3 interface: This interface allows the motor release to be interrupted via an isolated normally closed contact. PIN 1 (Motor stop OUT) and PIN 2 (Motor stop IN) are equipped with a jumper at the factory to ensure the motor is ready for operation.
Switch S2: Located on the board at the top front, this switch determines the function of the motor stop VM350. For LTS350D, S2 must be in position 1 for operation readiness. For LTE350D, S2 determines the VM350 motor stop function according to a specific table, and its setting must comply with the "Motor stop VM350" selection in the LTE350D channel configuration for operational readiness.

The device also features three LEDs on the front panel to indicate operating status:

BTB LED: Off indicates no power supply or that the device is in download mode. Green indicates ready for operation. Flashing green indicates not ready for operation but no system error, or that a motor stop has been triggered.
FG LED: Off indicates no servo amplifier release. Green indicates servo amplifier release.
Error LED: Red indicates a system error.
Reset button: When pressed, a reset is performed to reinitialize the tightening channel.
