Product Description:
S74802-NAF2-PA is a digital servo amplifier. It is designed and produced by Kollmorgen. The amplifier belongs to the S700 series. Its rated output is 48 Amps and the peak output is 96 Amps for 5 seconds. The input voltage range is 208 to 480 Volts AC. Three-phase input is required for normal operation. Single-phase AC input can be used for amplifier set up. The rated line power for continuous operation is 35 kVA. The S74802-NAF2-PA comes in an IP20 rated housing. Kollmorgen recommends installing the unit inside a switchgear cabinet. The optimal temperature for operation is 0 to 40 degrees Celsius. An integrated cooling fan is available on the unit. The recommended temperature for storage is -20 to 55 degrees Celsius. Unrestricted storage is possible for up to one year. For longer duration, capacitors on the unit require re-forming. Weight of the S74802-NAF2-PA amplifier is 13 kilograms. Its dimensions with connectors are 385 x 190 x 243 millimeters. Safe Torque Off (STO) safety feature is available as a standard option. Other standard features include RS-232, EtherCAT and CANopen communication interfaces, resolver and encoder based feedback, internal cooling fan and three slots for expansion cards. Slot 1 on the unit is unoccupied. Slot 2 is occupied by a fan control board used to reduce noise emission of the fan by reducing its speed and switching it on and off as required. Slot 3 on the unit is occupied by a position I/O monitor card. A card reader for memory cards is also available on the unit. The firmware and a full set of parameters can be stored on the memory card and reloaded onto the servo amplifier.
