Product Description:

The PE 100 servo amplifier belongs to the LTE Servo Amplifiers series engineered by Bosch Rexroth Indramat. This compact card sits between a motion controller and a power stage, shaping analog command signals so presses, stamping machines, or forming axes receive accurate current and voltage references. In an industrial automation cell, the module translates setpoints from the PLC into stable drive signals, allowing consistent tonnage, stroke length, and cycle timing without the drift that can occur with purely mechanical regulation.

It operates from a single-phase input of 110/220 VAC, eliminating the need for a dedicated three-phase supply in small cabinets. During steady operation, it draws only 0.3 A, which minimizes heat and reduces the capacity required for upstream circuit protection. The internal rectifier and filters accommodate a 50/60 Hz grid frequency, so the same unit can operate on North American or European power systems without modification. Conducted emissions are suppressed on the board, so no external line filter is required, simplifying installation and reducing the number of external components. Control wiring is concentrated in a 37-pin Sub-D interface that carries analog references, feedback signals, and status bits directly to a host PLC without separate terminal strips.

The amplifier’s current loop is tuned for LTE12/LTE45 power stacks, helping prevent overshoot when a press engages hard tooling. Coil or contactor pull-in can be actuated through either the X1 or X8 outputs, allowing the relay location to suit the machine wiring layout without changes to the board’s programming. The dedicated analog press control routine linearizes force feedback so each press cycle remains within the required tolerances as material thickness varies. Diagnostic LEDs and parameter codes provide operating status and adjustment access while supporting integration with other LTE devices used throughout the automation system.
