Product Description

The S7720C-NAF2-PA digital servo amplifier from Kollmorgen has a controlled fan in the second expansion card slot. This servo amplifier related connecting cables have to be bought as separate subitems. The product has an optimized resolver interface. This device can be installed in a small switchgear cabinet because of its integrated power supply and brake resistor as well as onboard EMC filters. The unit is compatible with SD and MMC type memory cards. It portrays a fast setup process because of autotuning, connectors for all connections, and a memory card for firmware and parameter updates. This amplifier uses a single cable for the Hiperface DSL and SFD3 feedback options.

The product comprises a Safe Torque Off function with two channels. This device has a PLC compatible enable input with a DGND reference ground. The unit has a software update rate of 250 µs for its digital inputs. Its failsafe braking can be achieved by using an additional mechanical brake. This amplifier has a ready-to-operate BTB/RTO contact. The product also features two STO enable inputs. This device associated position-control, operating, and motion-block parameters can be set up by using the DRIVEGUI.EXE software on a commercial PC.

The servo amplifier has an Ethernet interface with two RJ-45 connectors. This unit should be switched off before its memory card is inserted or removed. It is required to set up each servo amplifier individually in the case of multi-axis systems. The product encompasses inbuilt protection measures such as shielding or insulation that must not be removed. It should not be touched during its operation.
