Product Description:
The S74802-NANA-PA is a servo drive manufactured by Kollmorgen for the S700 Servo Drives series. Designed to modulate motor torque and velocity in industrial automation, it interfaces with motion controllers through onboard EtherCAT and CANopen networks. The device supplies regulated three-phase power to connected servomotors, executing precise drive commands needed for conveyor indexing, packaging axes, and other closed-loop positioning duties.
The drive operates on a supply range of 208 to 480 V, drawing a continuous power of 35 kVA while delivering a rated phase current of 48 Arms to the motor. For dynamic events such as rapid acceleration, it can source up to 96 Arms for short periods. The transistor output stage is clocked at 8 kHz, a switching frequency that reduces current ripple and allows tight current loops. Dual-channel STO provides safe torque off without external contactors, and the unit is cleared for 30 switching cycles per hour, making it suitable for applications with frequent start and stop sequences. Airborne sound pressure does not exceed 62 dB(A) during operation, supporting installation near operators. The housing measures 190 mm wide, 386 mm high, and 244 mm deep, fitting standard control cabinets. All functional electronics are built on standard PCBs, and the absence of an expansion card keeps the footprint compact while the integrated network interfaces satisfy most fieldbus requirements.
The command interface provides fine-grained analog channels for process signals. The input side has a resistance of 20 kΩ and resolves signals down to 1.25 mV, while the output channel supports a resolution of 0.38 mV across a bipolar range of ±10 V for feedback to legacy controllers. These analog parameters supplement the digital fieldbus ports when high-speed analog loops are required. The unit has a mass of 13 kg. The enclosure carries an IP20 rating, so additional shielding or cabinet mounting is necessary in dusty or wet zones.
