Product Description:
The KDA 3.1-100-3-A00-U1 Main Spindle Drive features stable control, consistent reliability and compatibility with updated programming modules. The drive supports precise input adjustments through keypad operation. The forced cooling technology maintains proper function under continuous operational load.
This KDA 3.1-100-3-A00-U1 spindle drive delivers strong performance with rated current of 100 A. Inputting and changing parameters is handled through the user terminal keypad that allows convenient configuration. The main spindle drive receives its speed command inputs through differential analog voltage signals in the range of ± 10 V. These command signals are typically generated by the CNC controller or motion control unit and represent a proportional reference. The unit operates without auxiliary encoder input or auxiliary interface. This compatibility guarantees reliable drive operation across different applications. The programming module update system keeps the drive technically current that allows fault clearance through software updates. Improved parameter values for the motor and drive combination are included in the update.
The KDA 3.1-100-3-A00-U1 spindle drive requires a + 24 V load voltage at 1.6 A and a ± 15 V measuring voltage at 160 mA. For thermal management, the drive uses forced cooling supported by an AC supply source of 115 V at 50 – 60 Hz for the heatsink blower. The blower unit has a weight of 4.2 kg that ensures adequate cooling efficiency. The mechanical mounting kit M1-KD is provided with the model that weighs 1.7 kg. This ensures secure installation and reliable positioning during setup. The permissible operating ambient temperature range for the model is + 5 °C to + 45 °C under nominal data. The permissible humidity rating for this spindle drive is class F that ensures durability in standard operating environments.
