Product Description:

The P60660-SDN-000 drive is produced by Kollmorgen as part of the P6000 Stepper Drives series. It is a panel-mounted electronic amplifier that supplies regulated phase current to two-phase stepper motors used in indexing tables, pick-and-place actuators, and similar automation axes. By shaping current through a bipolar chopper circuit, the unit converts incoming AC power into precise, variable step sequences for open-loop positioning tasks in industrial machinery.

The internal chopper operates at 20 kHz, keeping audible noise low while limiting current ripple in the motor windings. For the mains side, the drive draws up to 6.0 A RMS and can consume a maximum of 660 W when running high-torque applications. Command inputs can be pulsed at rates to 2 MHz, so the controller can follow very fine resolution motion profiles. Motor current is regulated to a maximum of 5.7 Arms per phase through the two-phase bipolar chopper circuit. Protection signaling is provided by an open-collector fault output rated to 100 mA at 30 VDC, while three mating connectors are supplied for logic, power, and motor terminations. Continuous service is supported in environments up to 90 % relative humidity and ambient temperatures not exceeding 40 °C.

Additional safeguards address transient and supply anomalies. The peak phase current limit of 8.0 A supports brief acceleration bursts without overstressing the power stage. Overvoltage shutdown activates at 430 VDC on the internal bus, and separate mains alarms warn at 295 VAC on the high side or 80 VAC on the low side to prevent uncontrolled operation. At 1.26 kg, the aluminum housing installs easily on DIN rail or bulkhead and imposes minimal load on cabinet structures. These alarms help prevent operation under unstable supply conditions.
