Product Description:

The 8EI8X8HWD10.0700-1 is an ACOPOS P3 servo drive designed by B&R Automation that accommodates up to a maximum installed load of 10 kVA and incorporates an EnDat 2.2 encoder interface. The drive is constructed to withstand 5 to 85% humidity without condensation and has an IP20 protection class in line with EN 60529 standards.

The 8EI8X8HWD10.0700-1 servo drive delivers 10 kW of peak power output and continuous power per motor connection of 4 kW on two motor connections. The maximum output frequency is 598 Hz. It accepts a 24 VDC power supply with ±25% tolerance. The braking resistor must have a minimum external resistance of 25 Ω and must be able to withstand 7 kW internal peak power as well as 25 kW external peak power. The encoder cable can be a maximum of 100 m, and the motor line has a maximum length of 75 m when the switching frequency is 5 kHz. The product has a weight of 4 kg and is for installation at elevations of 0 to 500 m. The enable input current at nominal voltage is about 9 mA. The DC bus capacitance rating is 470 µF. The modulation with respect to ground on trigger inputs is a maximum of ±38 V. UL and CSA wire size approvals are from 24 to 8 AWG. The switch-on time period is normally 60 seconds.

The 8EI8X8HWD10.0700-1 servo drive has an encoder power output voltage commonly at 11.4 V. It is applicable to industrial automation systems where high control accuracy and dependable power output are needed. Long cable runs for encoder signals and motor cables are supported in the product's design without signal attenuation. The operating humidity range and protection class of the device provide adequate environmental protection.
