Product Description:

The B8962 NP-LMTR is a dual-axis brushless servo drive produced by Kollmorgen within the B8000 Brushless Servo Smart Drives series. Designed as the power stage for linear motion platforms, the unit is factory configured for IDC linear motor operation so it can supply controlled current directly to ironless coils without mechanical transmission. In an automation cell, it connects between the motion controller and the motor feedback devices, generating precise force commands that move gantries, pick-and-place heads, or metrology carriages along a programmed path.

The drive handles 2 axes through independent current loops and operates from single-phase mains. Its apparent power demand is 2300 VA at 115 VAC and 4600 VA at 230 VAC, which helps determine the required transformer and breaker sizes. Continuous phase current is rated at 5 A continuous and 10 A peak, providing headroom for rapid acceleration. Thermal supervision forces a shutdown once the heat sink reaches 55 °C to protect the power stage. Position feedback enters through a differential quadrature TTL encoder input, and configuration data is exchanged over a serial link fixed at 9600 baud. Because the front panel is absent, all setup is completed through the host PC.

The communication layer uses an RS-232C interface that is separated from the power section through optically isolated receivers, which helps prevent ground loops when the drive is connected to external controllers. For incremental encoders, the unit supplies 5 VDC at 200 mA, so sensor power and differential signals can share the same connector. Eight logic terminals are available as 8 programmable inputs, and a matching set of programmable outputs can send status or handshake signals to a PLC. This arrangement supports device enable signals, limit switches, and user-defined events without additional interface modules.
