Product Description

The S7720A-PNF2-PA is a digital servo amplifier from Kollmorgen that should always be mounted in a closed control cabinet. The ventilation of the device should be unimpeded. The permitted ambient temperature should be maintained inside the control cabinet. The setup software of the unit, DRIVEGUI.EXE, can be used to alter the settings of the amplifier. However, any other alterations will void the warranty. The equipment must be installed and wired only when it is not live. The mounting position of the device is vertical. There is an LED display to show the status of the product.

The switching frequency of the output stage of the S700 digital servo amplifier is 8 kHz. The unit’s minimum motor inductance at 3x400V is 0.51 mH. The form factor of the output current of the device is 1.01. The bandwidth of the current controller of the product is greater than 1.2 (bis 5) kHz. The product dimensions are 390 x 600 x 400 mm. The current rating of the device is 72 Arms. The amplifier has a maximum stacking height of 3 cartons. It should be noted that if the permissible current or voltage values are exceeded, the device is prone to damage.

The S700 digital servo amplifier contains electrostatically sensitive components. These parts can be damaged if handled incorrectly. It is vital to always measure the voltage in the DC bus link and then wait until it has dropped below 60 V before handling the components. There is a card reader meant for memory cards on the top of the product. The device supports MMC and SD memory cards. The recommended tightening torque of the unit’s grounding bolt is 3.5 Nm.
