Product Description:
The 0190-A2460 is a servo drive from Kollmorgen, a well-known industrial automation company. This is part of their S600 series of 3-phase frequency inverter drives. It’s designed for industrial use and has a 230V input voltage, which is a common standard in many industrial applications. This input voltage powers the internal electronics and, ultimately, the motor. The drive is rated for 2 HP, which means it can handle motors of this power rating. This is a key factor to consider when selecting a drive, as it must be matched to the motor being controlled to get optimal performance and prevent overloading. The 0190-A2460 has a rated output current of 6A (RMS), which is the continuous current the drive can supply to the motor. It can also handle a peak output current of 12A for short periods (up to 5 seconds). This peak current is needed for handling temporary overloads or high torque during motor startup or acceleration.
The Kollmorgen 0190-A2460 also has a rated installed load of 4 KVA for S1 operation. This is the apparent power the drive can handle continuously and is critical for proper installation and sizing of the electrical supply. The drive has a rated DC bus link voltage of 290V to 675V. This DC bus voltage is derived from the rectified input AC voltage and is the main power source for the inverter stage of the drive. The drive’s output stage clock frequency is 8 kHz, which is configurable up to 16 kHz when the DC bus voltage (VDCmax) is limited to 400V. This clock frequency determines the switching speed of the power transistors in the output stage and directly affects motor control. A higher frequency can give better control and reduce motor ripple but may also increase switching losses. The drive has overvoltage protection with a threshold between 450V and 900V.
This critical safety feature protects the drive’s internal components from damage due to voltage spikes, ensures reliable operation, and prevents costly downtime. Other technical specs include a maximum load inductance of 40 mH and a minimum load inductance of 12 mH. These inductance values are critical for motor operation. Load inductance is the inductance of the motor windings, and staying within these limits prevents current spikes and ensures smooth operation. The drive has a residual voltage drop of 5V at the rated current. This is the voltage loss within the power stage of the drive and is important for calculating the actual voltage to the motor. When the output stage is disabled, the drive’s quiescent dissipation is 15W. This low power consumption, when disabled, means energy efficiency and cost savings during idle periods.
Frequently Asked Questions about 0190-A2460:
Q: What are the key electrical specifications of the 0190-A2460?
A: This drive operates on a 230V input voltage and delivers a rated output current of 6A (RMS), with a peak output current of 12A for up to 5 seconds. It supports a rated installed load of 4 KVA for continuous S1 operation.
Q: How does the output stage clock frequency impact performance?
A: The drive features an 8 kHz clock frequency, which can be configured up to 16 kHz if the DC bus voltage is limited to 400V. A higher clock frequency improves control precision and reduces motor noise but may slightly affect efficiency.
Q: What type of overvoltage protection does this drive offer?
A: The overvoltage protection threshold for this servo drive ranges from 450V to 900V, safeguarding the unit against voltage spikes that could damage internal components or disrupt performance.
Q: What are the load inductance requirements for the 0190-A2460?
A: The maximum allowable load inductance is 40 mH, while the minimum required inductance is 12 mH. These values ensure stable motor operation and prevent excessive current spikes.
Q: What are the power dissipation and residual voltage drop characteristics?
A: The residual voltage drop at the rated current is approximately 5V. When the output stage is disabled, the quiescent power dissipation is about 15W, ensuring energy-efficient standby operation.
