Product Description:

The 8EI2X2HWD10.0700-1 is a Servo drive from B & R Automation is a dual-axis control unit. It is designed for precise motion applications. The DC bus capacitance of the servo drive is approximately 1880 ?F to support energy stability during operation. At 24 VDC, it draws 0.9 A current plus motor brake consumption and has an input capacitance of 4310 uF.

The 8EI2X2HWD10.0700-1 servo drive runs with a three-phase input voltage range of 200 to 480 VAC. The axis of drive normally supplies a current of 2.2 Aeff. At its peak, it can provide up to 6 Aeff. The input frequency supported by the drive is between 50 - 60 Hz. The drive's nominal switching frequency is 5 kHz, with optional switching settings of 10 kHz and 20 kHz. It can handle 598 Hz of peak output frequency. Power dissipation remains efficient, with around 20 to 30 W per axis under typical load. The 8EI2X2HWD10.0700-1 servo drive uses natural convection for fanless cooling. This makes it suitable for quiet environments and closed control cabinets in industrial automation use. Its design supports wall mounting. It also includes a built-in internal braking resistor capable of handling 100 W continuous and 1.5 kW peak loads. An external braking resistor can also be added if needed.

The 8EI2X2HWD10.0700-1 servo drive weighs 2.4 kg. It features dimensions of approximately 276 mm in height, 63 mm in width, and 218 mm in depth. Safety features include hardwired STO functionality with encoder support. This enhances protection without compromising performance. The unit is supplied without plug-in modules and is delivered with accessory code 7. This includes a two-row connector set, a front cover, and an integrated braking resistor.

Frequently Asked Questions about 8EI2X2HWD10.0700-1:

Q: How does the STO feature in 8EI2X2HWD10.0700-1 enhance machine safety?

A: The STO (Safe Torque Off) ensures motor torque is disabled during faults, enhancing operator safety. It supports encoder feedback for precise monitoring in 8EI2X2HWD10.0700-1.

Q: Why is natural convection cooling used in 8EI2X2HWD10.0700-1 instead of forced air cooling?

A: Natural convection allows silent, maintenance-free operation. This suits enclosed automation cabinets and avoids the need for active cooling systems in 8EI2X2HWD10.0700-1.

Q: What advantage does the 5 kHz nominal switching frequency offer in 8EI2X2HWD10.0700-1?

A: A 5 kHz switching frequency offers better output waveform quality. This reduces motor noise and increases drive efficiency in 8EI2X2HWD10.0700-1.

Q: Why is dual-axis control important in the B & R Automation 8EI2X2HWD10.0700-1?

A: Dual-axis control reduces system footprint and cabling. It optimizes synchronized motion control in industrial applications using 8EI2X2HWD10.0700-1.

Q: How does a 1.5 kW peak braking resistor help during motor deceleration in 8EI2X2HWD10.0700-1?

A: It helps quickly absorb regenerative energy during deceleration. This prevents damage to internal components of 8EI2X2HWD10.0700-1 under high braking loads.
