Product Description:
Bosch Rexroth Indramat's KDA 2.1-150-3-A0I-U1 is an alternating current main spindle drive for controlling main spindle motors with current and speed regulation needs. Forced air cooling allows the drive to run continuously while efficiently dissipating heat.
The KDA 2.1-150-3-A0I-U1 drive is capable of supporting continuous spindle performance, due to its 150A current rating. Nominal data reduction is necessary due to a maximum ambient temperature of 55°C. Stable functioning within its design range is enabled by the voltage rating of 300V. The precise control of speed is made possible via the drive's analogue speed setpoint input, which has a range of ±10V. The ability to operate in a closed loop is made possible by the incremental encoder's output, which provides motor feedback. The drive does not support additional encoder input. With its 115V AC power source running at 50 to 60 Hz, the heat sink fan ensures a constant airflow. For nominal data, the ambient temperature can be anything from 5 to 45 degrees Celsius. The IP10 rating, in accordance with DIN 40 050, offers KDA 2.1 drive some basic protection. The maximum allowable installation elevation, derating-free.
A heat sink fan is incorporated into KDA 2.1-150-3-A0I-U1 AC main spindle drive to ensure that the operational temperature is maintained through forced cooling. This main spindle drive is designed to work with industrial automation systems that require regulated and controlled spindle operation. The drive meets operational standards without the need for derating up to 1000 meters. At temperatures exceeding 45°C, the drive's performance must be lowered, with a maximum restriction of 55°C. Performance under specified air moisture is guaranteed by the allowable humidity specification given in DIN 40 040.
Frequently Asked Questions about KDA 2.1-150-3-A0I-U1:
Q: Why does KDA 2.1-150-3-A0I-U1 use IP10 protection?
A: The IP10 protection ensures basic intrusion resistance against large solid objects. It helps safeguard internal components during general industrial usage.
Q: Does KDA 2.1-150-3-A0I-U1 support additional encoder input?
A: No, the drive does not support any additional encoder input. It only operates using its built-in incremental encoder output for feedback control.
Q: Why does KDA 2.1-150-3-A0I-U1 require 115V AC for fan?
A: The 115V AC supply powers the heat sink fan that provides continuous forced cooling. It helps maintain safe internal temperature during prolonged usage.
Q: How does KDA 2.1-150-3-A0I-U1 operate at high altitudes?
A: The drive operates without derating up to 1000 meters. Beyond that elevation, power output may need adjustment due to reduced air density.
Q: Why is the ambient temperature limit 55°C for KDA 2.1-150-3-A0I-U1?
A: The maximum ambient temperature of 55°C is permissible with reduced nominal data. This prevents overheating and ensures stable performance under heat stress.
