Product Description:
The S7720C-PBF2-NA is a servo drive manufactured by Kollmorgen for the S700 Servo Drives series. Positioned between a motion controller and a synchronous motor, the unit supplies modulated three-phase power and feedback processing that support high-precision positioning tasks in industrial automation cells, palletizers, and robotic stations. It also hosts network interfaces for PROFIBUS and PROFIdrive communication, allowing deterministic exchanges with PLCs while the drive’s integrated safe torque off channels help prevent unintended energization during maintenance or emergency stops.
The power section accepts a mains span of 208–480 V and delivers a continuous phase current of 72 Arms with a short-term ceiling of 140 Arms for acceleration peaks. Upstream infrastructure must supply up to 50 kVA, and excess energy that is not returned to the DC bus becomes heat, with dissipation reaching 1005 W at 400 V. The drive requires a minimum motor inductance of 0.51 mH to keep current ripple within the controller bandwidth. During steady operation, the internal logic incurs only a 6 V residual drop across the power stage, and each digital output can source 100 mA to external relays or sensors. The drive also includes a fan-controller expansion card that modulates cabinet airflow, and its PROFIBUS port supports 12 MBaud with PPO type 2 telegrams for cyclic data. Protective coordination calls for a 100 A fuse on the brake resistor circuit, allows thirty switch-on cycles per hour, and permits operation at up to 85% relative humidity.
The switching devices exhibit a dv/dt of 4.0 kV/µs, so shielded cabling and proper grounding are recommended to limit common-mode noise. Mains protection relies on an 80 A AC supply fuse, while the embedded safety logic provides dual-channel STO that meets current functional safety requirements without external relays. For installations where panel convection is inadequate, a factory option equips the drive with a cold-plate base to transfer losses to a liquid-cooled manifold under high ambient heat.
