Product Description:

The 502-03840-04R0 is an interface card engineered by Kollmorgen for the PIC900 Drives series. Installed alongside the main power section, it adds dedicated analog outputs and time-critical digital capture so the drive can command actuators and read position feedback in tightly synchronized motion loops. By concentrating these signal-conditioning functions on one board, the controller frees PLC bandwidth and shortens response time in automated assembly cells, packaging lines, and other multi-axis installations.

This board provides 4 analog output channels that can swing to a nominal range of ±11 VDC, allowing direct connection to torque-controlled or velocity-controlled amplifiers. Each channel is generated with 16-bit resolution, so the drive can trim motor current in 65,536 discrete steps. The converter refreshes every 32 µs, keeping analog error minimal even during rapid profile changes, and it can source or sink up to ±10 mA to satisfy typical servo input requirements. Total thermal impact on the cabinet is modest, with field power dissipation specified at 7.4 W. Command data passes to the plant wiring through a shielded harness, while the on-card position counter and latch buffers track motion when the host CPU is busy.

For feedback, the module accepts 3 encoder input channels and supports quadrature rates to 250 kHz as well as single-ended pulse streams to 500 kHz. The fast-input front end presents a resistance of 2.7 kΩ, drawing limited current from source devices at its 24 VDC nominal level and still tolerating surges to 30 VDC. A minimum pulse width of 0.6 µs ensures clean edge recognition, while the 24-bit position counter and matching 24-bit latch capture absolute shaft location without overflow during high-speed moves. All signals reach the PCB through a 40-pin card edge that mates with the backplane, keeping installation compact.
