FAQ
Q1:What does NANANA stand for in S77202-NANANA?
A1:
NANANA is Kollmorgen’s standard base configuration code. It means the servo drive is delivered as factory bare unit without optional expansion cards, hardware customization or special firmware, loaded with general standard program. It is the most basic and universal standard model, and hardware functions can be expanded later on demand.
Q2:What communication methods does this drive support? Can it connect to ordinary domestic controllers?
A2:
The unit is equipped with EtherCAT and CANopen buses, and also supports traditional pulse + direction control. It can connect to high-end bus motion controllers as well as conventional domestic pulse controllers. Both new and legacy control systems are compatible, matching most automation machine control schemes.
Q3:Can the built-in STO function meet machine safety certification requirements?
A3:
Yes. This model comes with dual-channel independent STO Safe Torque Off function up to SIL CL3 safety level, conforming to EU and domestic industrial machinery safety standards. It can be directly adopted in machine safety circuit design without additional safety relays and satisfy safety certification requirements for most industrial machines.
Q4:What power range of servo motors can this drive support? Can it work under heavy-load conditions?
A4:
Rated continuous output current is 72A with peak current 140A. It is designed for high-power heavy-load applications and can drive medium & large inertia high-power servo motors. It fully meets heavy-load, frequent start-stop and multi-axis synchronous high-intensity working conditions for machine tools, gantry equipment, material handling and other applications with excellent dynamic response and load stability.
Q5:Does the drive come with built-in cooling fan? How to use it under high ambient temperature?
A5:
The base version of S77202-NANANA has no built-in cooling fan and relies on natural heat dissipation. If the unit runs continuously under heavy load or the cabinet temperature is high, dedicated controlled fan option can be installed later to enhance heat dissipation and ensure long-term stable operation.
Q6:Can it drive third-party servo motors or only Kollmorgen motors?
A6:
This drive is not limited to original motors. It supports general feedback protocols including Resolver, SSI, AquadB, Hiperface DSL, compatible with most mainstream standard servo motors in the market. There is no binding requirement on original motors, lowering equipment matching cost.
Q7:How to back up and copy parameters in batch for mass equipment commissioning?
A7:
MMC memory card is supported. Commissioned parameters and firmware can be backed up to memory card with one click. Parameters can be imported in batch to multiple drives without tuning unit by unit, greatly improving efficiency for mass production, commissioning and maintenance.
Q8:What are the installation environment requirements for this drive?
A8:
IP20 protection class, for cabinet installation only. The installation environment shall be dry, free of corrosive gas and excessive dust with good ventilation. Direct use in open-air, humid, water-logged or heavily dusty harsh environments is forbidden, otherwise service life and operation stability will be affected.
