Product Description

The Kollmorgen S7720C-EIF2-PA digital servo amplifier must be used with a motor that has a rated voltage that is at least as high as the DC bus link voltage of the amplifier. The servo amplifier comprises integrated EMC filters that will not work with a DC input. This product needs a mains choke fitting if the mains voltage asymmetry is higher than 3%. The device must be checked at regular intervals for the safe switching of its pulse inhibitor to achieve PLe or SIL CL3. This unit must not be commissioned if the installation machine fails to comply with the low voltage directives. It controls the holding brake of the associated motor. This amplifier has a transportation class of 2K3 according to EN 61800-2 and EN 60721-3-1 specifications.

The product has a nameplate on the side of its housing. This device must be operated with the cabinet door closed. The unit produces a high voltage of up to 900 V during the operation phase. It may cause personnel injury due to electrical arcing or electrical shock. This amplifier must be matched with the motor in terms of current and voltage ratings. The product has a three-character LED display that highlights its current rating after the power has been turned on.

This device and its cables tend to get damaged because of excessively high fusing. The unit should be touched only ten minutes after the power is turned off. Its status is monitored by a PLC to acknowledge critical situations. This servo amplifier has a BTB/RTO contact that is wired in series into the emergency off circuit. The product needs to be wired correctly for its proper functioning in the servo system.
