Product Description

The Kollmorgen S7720A-EIF2-PM is a digital servo amplifier that features a three-character LED display for indicating its status. The setup software of the device can be used to adapt the brake circuit according to the electrical supply voltage. It must be noted that excessively high external fusing can endanger devices and cables. The behavior of the product always depends on the settings of the different parameters. The unit must be properly grounded on a conductive surface; otherwise, there is a high risk of electrical shock. An isolating transformer is needed for 400V to 480V networks, which are grounded asymmetrically or not grounded.

The rated input power of the S700 digital servo amplifier for continuous operation is 50 kVA. The device has a permitted switch on/off frequency of 30 1/h. Correct wiring is the foundation for the proper functioning of the servo system. The power and control cables should be routed separately. A distance of at least 200 mm is recommended. The recommended tightening torque for the X0 connector with up to 25 mm² of wire is 2.5 Nm. The equipment should be installed and wired only when it is not live. There is a nameplate attached to the side of the servo amplifier for identification.

The ventilation of the S700 digital servo amplifier should be unimpeded, and the permitted ambient temperature must be maintained within the control cabinet. There should be sufficient space above and below the device. The product offers a two-channel STO (Safe Torque Off) function. The function works by blocking the trigger pulses of the power transistors. The rated current of the unit is 72 Arms. The device has fast setup and autotuning features.
