Product Description:
Kollmorgen’s S700 Servo Drives series includes part S71202-NANANA-NA-022, a compact digital drive controller engineered to regulate synchronous or induction servomotors in automated machinery. Mounted in an IP20-rated housing, the device is intended for installation inside control enclosures where ambient cooling air is available. It integrates EtherCAT and CANopen communication layers, allowing machine PLCs to issue motion commands and read status without auxiliary gateways. By modulating its output according to velocity, torque, or position demand, the drive maintains precise axis performance for packaging equipment, pick-and-place robots, and material-handling systems.
The drive connects to three-phase mains in the 208–480 V range, allowing a single product to support low- and medium-voltage plant supplies. During continuous operation, it delivers 12 A RMS of output current, while brief accelerations can draw 24 A RMS for up to 2 seconds before the output returns to its nominal limit. This temporary current increase supports rapid indexing and sudden load changes. An internal switching stage operating at 8 kHz shapes the PWM waveform so the attached motor receives fine voltage resolution with low audible noise. The DC link can rise to 900 VDC during regeneration, and excess energy is dissipated through a built-in 33 Ω brake resistor. The associated brake circuit can absorb 100 W, helping control the bus voltage during deceleration.
A dual-processor architecture provides dual-channel STO, allowing the controller to remove torque-producing power without external contactors during Category 0 or Category 1 stops. During continuous operation, the electronics dissipate 160 W of heat, so cabinet airflow or a suitable heat sink must accommodate the thermal load. The housing measures 70 mm wide, 345 mm high, and 243 mm deep, providing a narrow installation footprint inside the control enclosure. Its aluminum chassis weighs 4.4 kg, permitting direct mounting on a suitable backplate without additional bracing. The IP20 enclosure protects against accidental contact with internal components while allowing the airflow needed for cooling. Adequate clearance around the housing helps prevent trapped heat from affecting nearby control equipment.
